Considered views on the OTR market.

Why the OTR tyre market is structurally inefficient, and what that means for buyers

Manufacturer allocation, opaque pricing, fragmented distribution. The inefficiency isn't an accident. It's been the operating model for decades. Here's what it looks like from inside the trade.

Most markets get more efficient over time. Information improves, distribution consolidates, prices converge, lead times shorten. The OTR tyre market has done none of that. After fifty years in it, the most useful observation I can offer a new buyer is this: the inefficiency is the model. It's not getting fixed. It's not a temporary glitch in supply. Build your procurement around it.

There are three structural reasons.

One: manufacturers ration the product

Premium OTR tyre capacity is constrained by design. The tier-one manufacturers, Bridgestone, Michelin, Goodyear, Yokohama, Continental, run their factories at high utilisation. They allocate output across contracted customers (tier-one mining contracts) and channel partners (regional distributors) using opaque, relationship-driven processes. Allocation isn't published. It isn't visible to the buyer. It often isn't even visible to the channel partner two levels down the distribution chain.

The practical effect: when you want a specific tyre on a specific date, the answer depends on where you sit in the allocation hierarchy. A tier-one mining contract gets answered first. A civil contractor with no contract gets answered last. The difference can be eight to fourteen weeks of lead time on exactly the same product.

This isn't a complaint about the manufacturers, they're managing scarce capacity through the channels they trust, which is rational. It's an observation about the market structure that buyers need to understand. You are not pulling product through an open market. You are being allocated, by people whose names you mostly don't know, against criteria that aren't published.

Two: pricing is opaque and relationship-driven

The price of an OTR tyre delivered to your gate is not a published number. It's a negotiated number, and the negotiation is between the manufacturer (or the channel partner) and you (or the trader you've engaged). The same tyre, same brand, same pattern, same week, can be priced anywhere across a 30 to 40% range depending on contract terms, volume, payment cycle, and the relationship.

I'm not arguing this should be different. Mature relationships justify better pricing. What I'm arguing is that the published "list price" of an OTR tyre, to the extent one exists, has limited bearing on what you'll actually pay. Procurement teams that benchmark against catalogue numbers will conclude either that they're being cheated or that they're getting an unbelievable deal, when in fact they're just dealing with the normal pricing variance of the market.

The published "list price" of an OTR tyre has limited bearing on what you'll actually pay.

Three: distribution is fragmented across overlapping channels

Every major manufacturer runs a primary distribution channel (the OEM-aligned route, Bridgestone Mining Solutions, Michelin Earthmover, etc.) and accepts secondary movement through trader and dealer networks. The same physical tyre can reach you through three or four different channels at three or four different prices, with three or four different lead times. There is no single, transparent ordering interface.

This is partly because manufacturers want it that way (it preserves their leverage), partly because the buyer base is too varied to serve through one channel (mining procurement and a regional civil contractor have genuinely different requirements), and partly because the trader network solves real problems, moving end-of-line stock, surplus from one mine to another, off-allocation product, bilateral swaps between competing fleets.

What it means for buyers

If the inefficiency isn't going to be fixed, the rational response is to design procurement that uses it rather than fights it.

• Don't rely on one channel. The OEM-aligned route has its place, particularly for warranty-critical primary fleet on tier-one mining contracts. But for the long tail of fleet, secondary machines, civil, ag, mid-tier mining, the independent trader route is consistently faster and often cheaper.
• Build a relationship with an independent trader before you need them. When the OEM channel says fourteen weeks and your machine is down today, you don't want to be starting a relationship from cold. The traders who can actually move things in a week did the work of getting to know your fleet, your sizes, and your standards months earlier.
• Be honest with the trader about what you'll pay. The market clears on pricing. If you have a budget number, share it. The trader can tell you whether the tyre exists at that price, or whether you're 15% off, or whether you're well above market and being slow-played by the OEM channel.
• Accept that mid-tier has earned its place in the middle of your fleet. The market structure ensures tier-one premium remains for the prime production positions. Secondary fleet, civil, ag, mid-tier brands clear at a credible delivered price with credible service expectations. Procuring 100% tier-one across a 60-machine civil fleet is over-paying for what the application requires.
• Track your own data. The market doesn't publish what each tyre actually cost you delivered, with what lead time, in what condition. Your own purchase history is the only honest dataset you have. Maintain it.

The OTR tyre market is what it is. It's not the worst market, pricing is fair, product is generally honest, lead times are real even if they're long. But it isn't an open, efficient, transparent market and it isn't going to become one. Procurement that accepts the structure rather than fighting it will out-perform procurement that doesn't.

Tier-one vs mid-tier: the real economics of OTR tyre purchasing in 2026

Tier-one premium remains justified for some fleet, and is overpaid for others. The honest read on when mid-tier earns its place and when it doesn't.

Opinion and analysis based on Jewell Tyres' independent trading experience, not financial, procurement or engineering advice, not manufacturer-verified test data, and not a statement about any product's safety or fitness for a particular application. Jewell Tyres trades these tyres commercially and our editorial reflects that trading perspective. Any figures are indicative estimates only; confirm against your own data before relying on them.

The tier-one versus mid-tier debate is older than I am in this trade, but it's a different argument in 2026 than it was even five years ago. The premium brands are still premium. The mid-tier brands have closed the gap in some sizes and applications, and not in others. The honest read isn't "buy tier-one for everything" or "buy mid-tier for everything." It's a position-by-position economic decision.

Here's how the calculation works in practice.

The tier-one premium is real, and so is the cost gap

In our trading experience, and as a rough working estimate only, for a Pilbara iron ore CAT 992K running 24/7 production, a Bridgestone VRDP in 45/65R45 will outlive a credible mid-tier alternative (BKT Earthmax SR468, Aeolus AL57) by something in the range of 15-30%. The exact number depends on cycle, ambient temperature, operator behaviour, and which mid-tier you're comparing against. The 15-30% range is the honest band based on what we see across trader movements.

The delivered price gap is in the range of 25-45%. Mid-tier is 25-45% cheaper, delivered. So on cost-per-hour of service, the tier-one premium is partially absorbed by longer life but doesn't fully close. For a tyre that costs $25,000 versus $16,000, tier-one ends up roughly $35-45/hour over its life versus $28-35/hour for mid-tier. These are indicative ranges from field observation, not manufacturer-verified test data; actual life and cost-per-hour vary widely by site, cycle, temperature and maintenance. Confirm against your own fleet data before relying on them.

On primary production fleet, meaning the machines whose downtime stops the haul or stops the dig, tier-one's cost premium is justified by downtime reduction, residual value, and supply continuity. If your CAT 992K is down for two weeks waiting for a tyre, the lost production cost dwarfs the tyre cost. Tier-one's tighter supply relationships and stronger casing for retread eligibility usually justify the premium for these positions.

Where mid-tier has earned its place

Secondary fleet, civil construction, ag and forestry, mine roads (water carts, fuel and lube trucks, light vehicles within a fleet), these are the positions where mid-tier has earned its place over the last decade.

• Secondary fleet at a mine. The third or fourth 992 in the row, the spare grader, the night-shift loader. Downtime is recoverable. Cost-per-hour matters more than absolute uptime. Mid-tier earns its place.
• Civil construction. Site conditions are variable, cycles change, machines move between jobs. The tier-one premium is harder to justify because the application doesn't push the tyre. Mid-tier (BKT, Triangle, Aeolus) has been the default for a long time.
• Ag and forestry earthmovers. Smaller machines, lower hours, more occasional use. Mid-tier has consistently earned its place here. Some of the Indian and Chinese manufacturers (BKT, MRF, Galaxy, Alliance) have invested heavily in ag and forestry-relevant patterns.
• Material handling and port. Solideal/Camso, Trelleborg, Galaxy, these are the credible names in industrial. Tier-one mining manufacturers don't always have the same depth here.

Where mid-tier still doesn't earn its place

To be clear about the other side of the argument:

• Giant haul truck on tier-one contract. CAT 793F, 797F, Komatsu 930E-class. 59/80R63, 53/80R63. The supply base is narrow. Tier-one casing eligibility for retread (significant residual value) is a real consideration. The cost-of-failure is high. Tier-one premium typically justified.
• Tier-one mining contract that specifies it. If the contract requires tier-one tyres, it requires tier-one tyres. The procurement decision was made upstream.
• Tyres going on highly observable production-critical positions. The 992 doing the iron ore. The wheel loader at the digger face. Failures are visible to mine management within hours. Tier-one's supply continuity and predictable life are worth the premium.

The honest read isn't tier-one vs mid-tier. It's tier-one for the positions that earn it, mid-tier for the positions that don't.

The decision framework that works

For each machine position, ask:

• Is the machine production-critical? (Stops haul, stops dig, stops the work.) Lean tier-one.
• Is downtime recoverable? (Spare machine available, secondary fleet, etc.) Lean mid-tier.
• Is the tyre on a tier-one mining contract? Tier-one.
• Is the application at the edge of tyre capability? (Hot ambient, long cycle, abrasive material, heavy duty.) Lean tier-one.
• Is the operator running a generalist civil or mid-mining operation? Mid-tier earns its place.

One more point. The tier choice should be made by position, not by fleet. There's a tendency in procurement to make a brand decision and apply it to everything, "we're a Bridgestone shop" or "we run BKT." Both are over-simplifications. The mature procurement programmes I see across Australia and New Zealand are running tier-one on the primary positions and mid-tier on the long tail, picking up the cost saving where the application allows.

That kind of programme is harder to administer (more SKUs, more supplier relationships, more decisions) and worth the work. The cost saving on a mid-sized civil fleet doing it well is in the range of 15-25% of total tyre spend, real money on a $2M annual programme.

Pilbara supply dynamics: what 18 months of disruption taught us

2024-25 was the most disrupted Pilbara tyre supply environment in two decades. Lead times trebled, prices moved 30-50%. Three lessons worth keeping.

Opinion and analysis based on Jewell Tyres' independent trading experience, not financial, procurement or engineering advice, not manufacturer-verified test data, and not a statement about any product's safety or fitness for a particular application. Jewell Tyres trades these tyres commercially and our editorial reflects that trading perspective. Any figures are indicative estimates only; confirm against your own data before relying on them.

The 18 months from mid-2024 through the end of 2025 were the most disrupted Pilbara OTR tyre supply environment I've worked in. Multiple factors stacked: a global shortage of premium 45/65R45 and 50/65R51 capacity, a rebalancing of Bridgestone allocation following what the trade press described as Yokohama-Goodyear consolidation discussions, the cost-and-availability impact of the Red Sea shipping disruption on Indian and Chinese imports, and ongoing aftermath of pandemic-era inventory unwinding.

Things have settled in 2026. Lead times are back to roughly 6-10 weeks for tier-one premium sizes (versus 18-30 weeks at peak), and pricing is no longer moving every quarter. But the period left some useful lessons that I think will keep mattering even as the market normalises.

Lesson one: Tier-one mining contracts buffer differently than secondary fleet

From what we could see in the market, the largest tier-one contract holders in the Pilbara iron ore trade held their tyre supply through the worst of 2024-25 with relatively minor disruption to primary production. Their tier-one allocation relationships held. Their pricing moved less than the broader market. Their lead times stretched but didn't break.

Secondary fleet at the same mines, civil contractors building haul roads, ag and forestry operators, and independent dealers all experienced something closer to the published market disruption. Lead times stretched to 18-30 weeks for some sizes. Pricing moved 30-50% on specific tier-one premium products. Mid-tier brands moved less dramatically but moved.

The lesson: the tier-one mining contract is a real risk-mitigation mechanism for the customers inside it. For everyone else, supply risk is real and worth quantifying. If you're a civil contractor with no allocation relationship, your supply continuity is the residual of what the tier-one customers don't take. In a tight market, that residual gets thin.

Lesson two: The independent trader market does what the OEM market can't

Through 2024-25, independent traders moved a meaningful share of the tyres that the OEM-aligned channels couldn't deliver. Off-allocation product. End-of-mine inventory from closing operations. Bilateral swaps between mines that had the wrong stock. End-of-line patterns that the OEM channel had de-prioritised but were still credible fitments for older machines.

For Jewell Tyres specifically, our volume moved up roughly 35% over the 18-month period, not because we suddenly became better at trading, but because the structural inefficiencies of the OEM channel got more acute. Buyers who had previously bought 90% through their primary supplier started buying 25-40% through trader channels. Some of them stayed there after the market normalised.

The independent trader route became less of a fallback and more of a parallel primary channel for a lot of buyers.

The lesson for buyers: build the independent trader relationship now. The version of you that has a longstanding relationship with two or three credible independent traders has materially better optionality than the version that's starting from cold when supply tightens. The cost of maintaining the relationship is small, a quarterly catch-up, occasional minor purchases, and the value when you need it is large.

Lesson three: Mid-tier earns its place in the buffer

Buyers who had standing approval to use mid-tier brands (BKT, Aeolus, Techking, Triangle) for secondary fleet positions came through the disruption in better shape than buyers who didn't. Mid-tier supply held when tier-one supply tightened, because the manufacturers and their distribution channels are differently structured. Indian, Chinese, and East European manufacturing absorbed some of the gap that the tier-one channels couldn't fill.

For procurement teams that had pre-qualified mid-tier alternatives, meaning the engineering review, the contract approval, the operator familiarity were already done, the substitution was straightforward. For teams that hadn't done that work in advance, the substitution required emergency engineering review, contract variation, and operator retraining in the middle of a supply crisis. Not ideal.

The lesson: pre-qualify mid-tier alternatives for the positions in your fleet where mid-tier is plausible. Have the engineering review documented. Have the contract terms specified. Have an operating familiarity test on a sample machine. Then, when you need to substitute, you're working from a position of preparation rather than reaction.

The market we're in now

Heading into mid-2026, the supply picture has eased. Tier-one premium 45/65R45 lead times are back to ~8 weeks for non-contract buyers, down from 25+ at peak. Bridgestone, Michelin, and Yokohama all appear to be adding capacity over 2026-27. Pricing has stabilised, though it hasn't reversed the 2024-25 increases.

What I don't think reverses is the structural learning that buyers did through the disruption. Procurement teams now know that supply continuity is not guaranteed even at scale. They know that the trader market is a real channel. They know that mid-tier is genuinely viable for the long tail of fleet. None of that knowledge gets unlearned in a normal market. The next supply shock, and there will be one, finds a more resilient buyer base than the last one did.

How big is Australia's off-the-road tyre market? Reading the numbers from the trade

On published estimates the market is worth around AUD 208 million (2023), heading past AUD 300 million by 2032. That number is the easy part. What it means for a buyer is where the trade read comes in.

People ask us how big the off-the-road tyre business actually is in Australia. It's a fair question, and there's now a public number to point at. The independent research firm Credence Research puts the Australia off-the-road tyre market at about AUD 208 million in 2023 (USD 135.29 million), and projects it to reach about AUD 317 million by 2032 (USD 206.22 million), growing at a compound annual growth rate of about 4.78% from 2025 to 2032. For global context, the same firm sizes the worldwide OTR tyre market near AUD 28 billion in 2023 (USD 18.2 billion), heading toward about AUD 42 billion by 2032 (USD 27.1 billion) at about 4.5% a year.

Source: Credence Research, Australia Off-the-Road Tire Market (base year 2024). USD figures converted to AUD at an indicative AUD 1 = USD 0.65, rounded.

What a mid-single-digit growth rate actually tells you

A 4.78% growth rate isn't a boom, and it isn't meant to read like one. What it describes is a mature, mining-anchored market that expands in line with equipment fleets and production tonnes rather than in speculative bursts. That matches what we see from inside the trade. OTR tyre demand in Australia doesn't ride hype cycles. It tracks how many haul trucks, loaders and graders are turning dirt, and how hard they're being worked. When iron ore and coal production hold, tyre demand holds. When a mine ramps or a new pit opens, tyre demand steps up with it.

The practical read for a buyer: this is not a market where oversupply is going to rescue you with cheap product. Steady demand against constrained tier-one capacity is exactly the setup that keeps lead times and pricing firm. The structural inefficiency we wrote about in Note 01 doesn't get competed away by a 5%-a-year market.

The demand is where the mining is

On Credence Research's segmentation, the market splits along mining geography, and that lines up with the trade exactly. Western Australia is the dominant region, the Pilbara iron ore machine, followed by Queensland on the back of coal, then New South Wales, with South Australia and Victoria making up the balance. Nothing there will surprise anyone who's shipped a set of 45/65R45s lately. It's why an "independent Australian OTR trader" is, in practice, a business pointed at a handful of mining regions with a long tail of civil, quarry and agricultural work around the edges.

The research also segments the market by tyre construction (radial, bias and solid), by application (mining, construction, agriculture, industrial and port), and by size band (below 31 inch, 31 to 40 inch, 41 to 45 inch, and above 45 inch). The big-money end of our world sits in those top size bands, on the mining application, in radial construction. That's the concentrated, high-value core the market-size number mostly represents.

Why the tyres cost what they cost

The figure that makes buyers outside mining blink is the per-tyre cost. Credence Research cites mining dump-truck tyres running from around AUD 8,000 to over AUD 30,000 each (USD 5,000 to over USD 20,000), with the largest mining tyres averaging near AUD 69,000 (USD 45,000). Those numbers are real, and they're not a markup story. A giant radial is a constrained, highly engineered product: limited tier-one capacity, enormous amounts of material, long build times, and freight to the far side of the world. Price it against downtime, where a stopped haul truck costs far more per hour than the tyre under it, and the spend starts to make sense. That economics is precisely why the buy-versus-mid-tier decision matters, and we've laid out our honest read on it in Note 02.

Where our view differs from the spreadsheet

A market-size report is a useful reference point and a poor operating manual. Two things it can't capture, and both matter more to a buyer than the headline number:

• The number is a revenue snapshot, not an availability guide. A market can grow at a tidy 4.78% and still leave a non-contract buyer waiting eight to fourteen weeks for a specific size. Aggregate value tells you the market is healthy. It tells you nothing about whether your tyre is on a shelf.
• The trader channel is largely invisible to it. Off-allocation product, end-of-mine inventory, bilateral swaps between operations. The flows an independent trader lives on don't show up cleanly in a top-down market model. In our experience that channel gets proportionally bigger, not smaller, whenever the market tightens.

So take the figures for what they are: a credible, independent estimate of the market's shape and direction, useful for anyone sizing up the sector. Then buy on the ground truth, capacity, allocation and lead time, because that's what actually determines whether you get your tyres.

Common questions on the numbers

How big is the Australian OTR tyre market? Credence Research values it at about AUD 208 million in 2023 (USD 135.29 million), projected to about AUD 317 million (USD 206.22 million) by 2032 at about 4.78% a year (2025 to 2032). These are third-party estimates. We cite them, we don't produce them.

Which states drive demand? Western Australia leads on Pilbara iron ore, then Queensland on coal, then New South Wales, with South Australia and Victoria behind. Demand follows mining activity.

Why are mining tyres so expensive? Constrained tier-one capacity, sheer size and material, long build times and freight. Published ranges run into the tens of thousands of dollars per tyre for the largest sizes, and they're cheap next to the downtime they prevent.

How big is the global OTR earthmover tyre market?

Three respected research houses put the global OTR tyre market at somewhere between roughly AUD 40 billion and AUD 52 billion for 2025, all growing at mid single digit rates. The spread tells you more about how each firm defines the market than about the market itself.

Ask three research firms how big the global OTR earthmover tyre market is and you get three different numbers. That is not a reason to distrust the data, it is how market sizing works when each firm draws its own boundary around what counts as an OTR tyre. As an independent trader we care less about which single figure is right and more about what all three agree on: this is a large, mature market growing at a steady mid single digit rate, not a niche corner of the tyre industry.

Three numbers, one market

Mordor Intelligence puts the 2025 global OTR tyre market at AUD 40 billion (USD 26.17 billion), heading to AUD 50 billion (USD 32.81 billion) by 2030 at a compound annual growth rate of 4.63 percent. MarketsandMarkets, working from a 2026 base year, has AUD 40 billion (USD 26.32 billion) growing to AUD 50 billion (USD 32.63 billion) by 2032, a CAGR of 3.6 percent. IMARC Group is the outlier on size, putting 2025 at AUD 52 billion (USD 33.7 billion) and 2034 at AUD 76 billion (USD 49.1 billion), a CAGR of 4.14 percent.

Line all three up and the base year figure alone ranges from roughly AUD 29 billion to AUD 52 billion (USD 19 billion to USD 34 billion) depending on which report and which year you read. That is a wide band for what is supposedly the same market.

Why the numbers disagree

In our experience the gap comes down to definitions, not disagreement about demand. A market report's headline number depends on what gets counted in and what gets left out.

• Some reports count OTR tyres alone, others fold in wheels, retreading and related services.
• Segment scope varies: mining, construction, agriculture and ports are sometimes all included, sometimes only the largest segments are modelled.
• Base years differ (2025, 2026), so figures are not always measuring the same twelve months.
• Currency and regional coverage assumptions differ between publishers, which shifts the total before growth is even applied.

None of that is a criticism of the firms involved, each is transparent about its own methodology. It is simply a reminder that a market size figure is a modelled estimate, not a measured fact like a company's turnover.

What actually holds up across all three

Strip away the base year argument and the three reports tell a consistent story. The global OTR tyre market is worth tens of billions of dollars, it is not shrinking, and it is not growing explosively either. Every published CAGR sits in a tight mid single digit band, 3.6 percent from MarketsandMarkets, 4.14 percent from IMARC Group, 4.63 percent from Mordor Intelligence. That consistency across independently built models is, in our opinion, more useful to a buyer than any single headline figure.

A market this size and this steady is not driven by one customer or one commodity cycle. It moves with mining capex, construction activity and fleet replacement cycles across multiple continents, which is exactly why it does not swing wildly year to year.

What it means for an Australian buyer

For an Australian OTR buyer or fleet operator, the practical takeaway is not which forecast to trust, it is that global demand for earthmover tyres is broad based and growing gently, which supports continued investment by manufacturers in new compounds, sizes and supply. That is a reasonable backdrop for sourcing decisions, even though none of these global figures tell you much about pricing or availability here at home.

Note 04 on this site covers the Australia specific figure, which is the number more directly relevant to local fitment and pricing decisions. We would treat the global figures here as context for the broader industry, not as a substitute for local market conditions.

Common questions on the numbers

Why do OTR tyre market size reports vary so much between firms? Mainly definitions. Different reports include or exclude wheels and services, cover different segments (mining, construction, agriculture, ports), and use different base years. Mordor Intelligence, MarketsandMarkets and IMARC Group each build their own model, so the totals are not directly comparable even though the underlying market is the same.

What growth rate should I actually rely on? Rather than picking one figure, look at the range. All three sources land in a mid single digit CAGR band, from 3.6 percent (MarketsandMarkets) to 4.63 percent (Mordor Intelligence), with IMARC Group at 4.14 percent. That convergence is more informative than any single number.

Is the global OTR tyre market growing or shrinking? Growing, modestly. Every figure supplied by Mordor Intelligence, MarketsandMarkets and IMARC Group shows steady expansion out to 2030 to 2034, none show contraction.

Where does the real OTR tyre volume actually sit?

Most of the noise in this trade is about new equipment and OEM fitments. Most of the actual buying happens somewhere else entirely, and that somewhere else is where an independent trader earns a living.

Talk to most people about the OTR tyre trade and the conversation drifts straight to new machines, what the mine is ordering, what the dozer or the haul truck came fitted with from the factory. That is not where the volume actually sits. On the figures, the real game is the replacement market, tyres going back onto equipment that is already working, and that is a market an independent trader is built for.

Source: Mordor Intelligence, OTR Tire Market (2024 shares). Figures as reported, no currency conversion applies.

Aftermarket, not OEM, is where the money moves

Mordor Intelligence puts aftermarket demand at 73.27% of the OTR tyre market. In plain terms, roughly three tyres out of four sold are going onto equipment that is already in a fleet, not out the door on a new machine. OEM fitment gets the attention because it is tied to equipment sales figures that get reported and talked about. The replacement cycle does not make headlines the same way, but it is the bigger number and it repeats every time a tyre wears out, which in earthmoving is often.

For an independent trader this is the whole opportunity. We are not equipment dealers and we are not chasing OEM supply contracts that reward scale and long lead times. We are set up to move on replacement demand: available stock, fast turnaround, a fitment that matches what is actually on the machine rather than what left the factory five years ago.

Radial has become the default, and that changes buying behaviour

Radial construction now accounts for 66.71% of the OTR market, according to Mordor Intelligence. Bias tyres have not disappeared, and there are still applications where they make sense on cost or duty cycle grounds, but radial is the pattern most buyers are replacing into now. That is a shift worth naming plainly because it changes what a trader needs to stock and quote against.

• Radial casings carry a different price point and a different repair economics conversation than bias.
• A buyer replacing bias with radial is often re-evaluating total cost per hour, not just matching what was there before.
• Stocking against radial demand means carrying the sizes actually being replaced, not the sizes that were common a decade ago.

Rim size and application tell you where the everyday volume sits

Below-31-inch rim sizes are the largest equipment class by share at 38.73%, and construction is the largest application segment at 37.18%, both per Mordor Intelligence. Earthmovers account for 24.52% of equipment demand. Put those together and the picture is not the giant mining rim everyone pictures when they hear OTR. It is the smaller and mid-size gear working construction sites, quarries and civil jobs, wearing through tyres at a pace that keeps a trader's phone ringing.

In our opinion, this is the segment an independent trader should be built around. The big mine-spec rim business exists and matters, but it is a smaller, more contract-driven slice than the everyday construction and earthmoving replacement work that below-31-inch and construction-application numbers point to.

Where the growth is, and where the base volume is, are two different places

Asia-Pacific is the largest OTR region at 38.33% of demand, Mordor Intelligence reports, which lines up with the scale of construction and resources activity across the region. Middle East and Africa is the fastest growing region on a 4.71% CAGR basis. Those are two different signals: one tells you where the volume already is, the other tells you where it is heading.

For an Australian trader neither number is a direct read on the local market, but both are useful context. Australia sits inside a region with the largest base demand globally, and adjacent markets are growing fastest off a smaller base. Read together with the aftermarket and radial shares, they reinforce the same point: replacement work in construction and earthmoving segments is the durable volume, wherever you are trading.

Common questions on the numbers

Does this mean OEM fitment does not matter? No. OEM fitment still matters, particularly for equipment dealers and fleets buying new gear. But at 73.27% aftermarket share (Mordor Intelligence), the bulk of tyre spend happens after the machine is already working, which is the part of the trade an independent trader is positioned to serve.

Is bias construction finished? Not finished, but no longer the default. Radial holds 66.71% of OTR construction according to Mordor Intelligence, so bias is now the minority pattern in most replacement decisions, kept for specific duty cycles rather than as the standard choice.

Why focus on below-31-inch rims rather than big mining tyres? Because that is where the largest single equipment class share sits, at 38.73% (Mordor Intelligence), and construction is the largest application at 37.18%. Big mine-spec rims are a real and valuable segment, but the everyday replacement volume is concentrated in smaller and mid-size gear.

Why is the mining haul-truck tyre the fastest-growing part of the OTR market?

New market data shows rigid dump truck tyres growing well ahead of the broader OTR sector, with the big rim sizes and Asia-Pacific demand leading the charge. Here is what that means for buyers running haul fleets.

Every few years someone in this trade tells you the OTR market is one thing, growing at one speed. It is not. New research from MarketsandMarkets breaks the OTR tyre market down by equipment type and rim size, and the picture that comes out is clear: rigid dump trucks, the big haul units that shift ore and overburden all day in a mine, are pulling away from everything else. If you trade in giant tyres for rigid dump trucks, this is the segment that matters, and the numbers say it is only getting bigger.

Source: MarketsandMarkets, OTR Tires Market (May 2025). USD converted to AUD at an indicative AUD 1 = USD 0.65, rounded.

The headline number: rigid dump trucks are growing faster than the market that contains them

MarketsandMarkets puts the whole OTR tyre market at AUD 40.5 billion (USD 26.32 billion) in 2026, rising to AUD 50.2 billion (USD 32.63 billion) by 2032, a CAGR of 3.6%. That is steady, unremarkable growth for a mature industrial category. But inside that number, rigid dump trucks are tracking at more than 9% CAGR by value, the fastest-growing equipment segment MarketsandMarkets identifies in the entire OTR market.

In my opinion, that gap matters more than the headline growth figure itself. A market growing at 3.6% overall but with one segment running at 9%+ is not evenly spread demand, it is demand concentrating. Fleets, tyre distributors and traders who are positioned in general-purpose OTR (graders, loaders, smaller earthmovers) are riding the slow lane. Anyone set up for rigid dump truck tyres is riding the fast one.

Why the big rim sizes are the tell

MarketsandMarkets also breaks the market down by rim diameter, and the 25 to 30 inch rim class comes out as the fastest-growing rim size at more than 4% CAGR. That class sits squarely in haul truck territory, the fitments you find on the mid-size to large rigid dump trucks that do the bulk of hauling in open-cut mining and quarrying operations worldwide.

• A market growing fastest in equipment type (rigid dump trucks) and fastest in a rim size that matches that equipment (25 to 30 inch) is not a coincidence, it is the same growth story told two ways.
• That gives more confidence in the trend than either figure would on its own.

For a trader, rim size data is arguably more useful than equipment-type data, because it is rim size that decides what actually sits in a warehouse or gets sourced against a customer order. Seeing the 25 to 30 inch class lead the field is a direct signal about where stock, sourcing relationships and pricing knowledge need to be sharpest.

Asia-Pacific is where the volume sits, but that is not the whole story for an Australian buyer

MarketsandMarkets has Asia-Pacific holding more than 50% of global OTR tyre market value, which will not surprise anyone who has watched mining investment in the region over the past decade. Australia sits inside that Asia-Pacific footprint, and our own haul truck fleets, from iron ore in the Pilbara to coal and gold operations elsewhere, are part of what is driving that regional share.

My take is that this regional weighting cuts both ways for an Australian buyer. It means the region we operate in is the centre of gravity for the product, which should in theory mean better access to supply and more competitive sourcing over time. It also means we are competing for the same tyres, the same production slots and the same shipping capacity as every other Asia-Pacific mining market. Being in the right region for demand does not automatically mean an easy or cheap supply chain, and I would not treat regional dominance as a guarantee of favourable pricing.

What this means if you run or supply a haul fleet

None of this is engineering advice or a procurement recommendation, it is a trader's read of where the money and the growth are going. If rigid dump truck tyres are growing at more than double the pace of the OTR market as a whole, and the rim sizes that fit those trucks are leading rim-size growth too, then the commercial argument for specialising in this segment, rather than treating it as one line item among many OTR products, gets stronger with each new data release.

• Fleets should expect this segment to attract more supplier attention and more competition for allocation over time, not less.
• Buyers who lock in reliable sourcing relationships for the 25 to 30 inch and larger rim classes now are working with, not against, where MarketsandMarkets says the growth actually is.
• A trader whose core business is exactly this tyre class is not chasing a niche, on these figures it is chasing the part of OTR that is expanding fastest.

Common questions on the numbers

Is the rigid dump truck tyre segment really growing faster than the rest of the OTR market? Yes, on the figures MarketsandMarkets published in May 2025. Rigid dump trucks are tracking at more than 9% CAGR by value to 2032, against 3.6% for the OTR market overall, making it the fastest-growing equipment segment the report identifies.

What rim sizes matter most for haul truck tyre buyers? MarketsandMarkets identifies the 25 to 30 inch rim class as the fastest-growing rim size in the OTR market, at more than 4% CAGR. That class covers a large share of rigid dump truck fitments, which lines up with the equipment-level growth data.

Does Asia-Pacific's share of the OTR market help Australian buyers? Asia-Pacific holds more than 50% of global OTR tyre value, per MarketsandMarkets, and Australia sits within that region. It puts local buyers close to the centre of demand, but in our opinion it also means competing with the rest of the region for the same supply, not an automatic pricing advantage.

How Much OTR Tyre Demand Does the Pilbara Actually Create?

The Pilbara's three big iron ore producers moved roughly 800 million tonnes in 2024. We work through what that tonnage means in giant OTR tyre replacements, a number no global market report ever counts properly.

Every global OTR tyre market report talks in vague billions of dollars and never once mentions the Pilbara by name, which is a strange omission given it is one of the densest concentrations of giant earthmover tyres on the planet. We buy and sell into this market, so we thought it was worth doing the sum ourselves. How much tonnage actually moves through the Pilbara, how many ultra-class haul trucks does that imply, and how many giant tyre replacements does that fleet burn through in a year. Nobody publishes this number directly. You have to build it yourself from the production reports.

Source: Rio Tinto Q4/FY2024 production results, BHP FY2024 operational review (SEC 6-K), Fortescue FY2024 shipments. Figures are tonnage, not currency, so no AUD conversion applies.

Turning tonnage into truck numbers

You cannot get a truck count straight out of a production report, but you can reason towards one. Rio Tinto alone is targeting 345 to 360 Mtpa in its medium-term objective, and that tonnage does not move on conveyor belts and rail alone. A meaningful share of it is dug, loaded and hauled by ultra-class rigid trucks in the 220 to 290 tonne class, the Cat 793 and Komatsu 930E being the two names you see everywhere out there. Each of those trucks runs on 6 giant OTR tyres. Scale that across three major producers each running large haul truck fleets across their Pilbara operations, and the tyre population at any one time is substantial, before you even get to the loaders, dozers and graders that also chew through giant and large OTR rubber on the same haul roads.

In our opinion, this is the detail that global market reports miss every time. They size the OTR tyre market in dollars, aggregate across mining, construction and ports, and never break out a single region's truck fleet against its production tonnage. The Pilbara is different because the tonnage is enormous, the haul cycles are brutal, and the fleet composition is unusually concentrated in the largest tyre sizes there are.

Why 4,000 to 8,000 hours matters more than the tonnage headline

The tonnage figures get the headlines, but the number that actually drives our order book is tyre life in hours. On hard Pilbara haul roads, giant OTR tyres typically last 4,000 to 8,000 hours before they are pulled, based on what we see trading into the segment. That is a wide band, and where a fleet sits in it depends on haul road condition, grade, payload discipline and heat, all things that vary pit to pit even within the same producer's own network.

• A truck run hard on steep grades and poorly maintained haul roads can burn through a tyre set well before the 4,000 hour mark.
• A well managed fleet on graded, watered roads can stretch tyres towards the 8,000 hour end.
• Multiply either figure across a six-tyre truck and a fleet running near continuously, and you get a replacement cadence that does not slow down even if iron ore prices do.

That is the commercial point for us as a trader. Tonnage targets like Rio Tinto's 345 to 360 Mtpa medium-term objective tell you the direction of travel for fleet size, but tyre hours tell you how often the phone rings.

What this means for an Australian OTR buyer

If you are buying giant OTR tyres for use anywhere near the Pilbara, or competing for business that services fleets there, the practical read is that demand is structurally high and does not track the iron ore price the way people assume. Rio Tinto, BHP and Fortescue combined moved roughly 800 Mt in 2024 on their own reported figures, and none of the three signalled a pullback in haul truck fleet size. Tyres wear on hours and tonnage hauled, not on the spot price of iron ore, so even in a softer price environment the replacement cycle keeps running.

Our opinion, as an independent trader and not as anyone's tyre engineer, is that buyers should treat Pilbara-scale demand as a baseline for giant OTR tyre availability across the whole Australian market, not just the mine sites themselves. When three producers each running large truck fleets are all drawing on the same global giant tyre supply chain, availability and lead times for buyers elsewhere in Australia move with that demand, whether those buyers are in the Pilbara or not.

The gap in global reporting

Global OTR tyre market reports are built bottom up from segment and application data across the world, and the Pilbara simply does not get its own line item. That is understandable from a global analyst's chair, but it means anyone using those reports to plan Australian giant tyre stock is missing the one dataset that actually matters here: how much tonnage the three Pilbara majors are moving, and how that converts to truck fleet size and tyre hours on the ground.

We think that gap is worth closing with primary numbers rather than global averages, which is why we built this note from the producers' own disclosed shipment figures rather than a market research estimate.

Common questions on the numbers

How much iron ore does the Pilbara actually produce? In 2024, Rio Tinto shipped 328.6 Mt from the Pilbara, BHP's WAIO business shipped 287 Mt in FY2024, and Fortescue shipped a record 191.6 Mt in FY2024. Combined, that is roughly 800 Mt a year across the three majors.

How many tyres does a Pilbara haul truck use? An ultra-class rigid haul truck such as a Cat 793 or Komatsu 930E, carrying 220 to 290 tonnes, runs on 6 giant OTR tyres. Multiply that across each producer's haul truck fleet and the tyre population is substantial.

How long do giant OTR tyres last in the Pilbara? In our trading experience, giant OTR tyres on hard Pilbara haul roads typically last 4,000 to 8,000 hours before replacement, depending on haul road condition and how the fleet is operated.

How many giant tyres will Fortescue's electric fleet switch need?

Fortescue's Liebherr deal is not just a headline about batteries. It is a dateable order for roughly 2,160 giant OTR tyre positions across this decade.

When Fortescue put its name to an AUD 4.3 billion (US$2.8 billion) order with Liebherr in August 2024, most of the coverage went straight to batteries, autonomy and decarbonisation targets. We read it differently. Strip out the corporate framing and what is left is a fleet renewal schedule, and fleet renewal schedules are what move giant OTR tyres. This note works through what that single order means in tyre positions, and why we think it is worth watching closely if you trade or supply in this size range.

Source: Mining Weekly (16 August 2024). USD converted to AUD at an indicative AUD 1 = USD 0.65, rounded. The tyre position figure is our own calculation from the truck count, not a figure published by the source.

From capex line to tyre count

Mining Weekly reported the deal as 475 machines in total, with 360 of those being autonomous battery-electric haul trucks. That is the number that matters to us. Every haul truck this size runs on six tyres, so 360 trucks is a proxy for around 2,160 giant OTR tyre positions that Fortescue will need to fill as these machines are delivered and commissioned through the rest of this decade.

That is not a one-off purchase. It is an entry point, and then an ongoing consumption schedule once the trucks are actually working a Pilbara duty cycle. New machines still wear tyres, still need spares, still need replacements when a cut or a heat event takes one out early. The order date gives us a rough start point. The tyre demand runs well beyond it.

Why this is different to normal fleet turnover

Fortescue told the market this replaces roughly two-thirds of its existing haul fleet, according to Mining Weekly. That is a big chunk of one company's fleet moving in a defined window, not a gradual trickle of like-for-like replacements spread over many years. In our opinion, batches of this size are what actually move a regional tyre market, because they concentrate demand into a shorter period rather than spreading it evenly.

It also sits on top of, not instead of, the fleet Fortescue already runs. Mining Weekly notes the company already operates more than 200 diesel autonomous haul trucks. Those machines do not vanish the day the new electric trucks arrive. There is a transition period where both fleets need tyres, which is worth remembering if anyone assumes the diesel side simply stops consuming rubber.

What we think it means for buyers in this size range

• A single named order gives the market a dateable, quantified demand event, rather than a vague sense that "electrification is coming".
• Roughly 2,160 tyre positions from one deal is meaningful scale in giant OTR sizes, on our reading of the Mining Weekly figures.
• We would treat this as a lead indicator, not a settled outcome, if you are securing supply agreements or planning stock. Delivery schedules for autonomous electric haul trucks of this scale can slip, and actual tyre consumption depends on how hard the fleet is worked once commissioned.
• We would read this alongside the broader Pilbara demand pool we set out in Note 08, since Fortescue is one large buyer inside a bigger regional picture, not the whole story on its own.

Where we would be cautious

Our 2,160 figure is a proxy built from a simple six tyres per truck assumption, applied to the 360 truck number Mining Weekly reported. Fortescue has not, as far as we can see, published a tyre order or a tyre budget attached to this deal. Treat the figure as a reasonable estimate of scale, not a confirmed procurement number.

We also have not seen a published delivery timetable for all 360 trucks, so we are not able to say how the 2,160 positions land year by year across this decade. What we can say, on the figures Mining Weekly has put on the record, is that this is a real, sizeable and dateable slice of future giant OTR demand, and one worth tracking rather than dismissing as just another mining company press release.

Common questions on the numbers

How many tyres does the Fortescue-Liebherr deal actually represent? Mining Weekly reported 360 autonomous battery-electric haul trucks as part of the deal. At six tyres per truck, that is roughly 2,160 giant OTR tyre positions, on our estimate, not a figure Fortescue itself has published.

Is this replacing Fortescue's whole fleet? No. Mining Weekly reports the 360 trucks replace roughly two-thirds of the existing haul fleet. Fortescue already runs more than 200 diesel autonomous haul trucks, which Mining Weekly says continue alongside the new electric machines during the transition.

What is the deal worth in Australian dollars? Mining Weekly reported the deal at about AUD 4.3 billion (US$2.8 billion), at an indicative AUD 1 = USD 0.65 conversion.

How Big Is Coal in Australia's OTR Tyre Market?

Coal is the quiet second half of Australia's OTR tyre market. Production keeps climbing even as thermal export earnings ease back from boom levels, and that split matters for anyone stocking or buying haul truck tyres.

Iron ore gets most of the attention when people talk about Australian OTR tyre demand, but coal is not far behind it. The Bowen Basin and Hunter Valley haul fleets together make up the second-largest OTR consuming pool in the country, and the underlying numbers from the Australian Government's Resources and Energy Quarterly (December 2024) tell a more layered story than the headline coal price would suggest.

Source: Australian Government, Resources and Energy Quarterly (December 2024). Figures shown in AUD as reported.

Production is still climbing, and that is what moves tyres

National coal production hit about 550 million tonnes in 2024, up 2.8% on the year before, according to the Resources and Energy Quarterly. In our opinion that is the number that matters most for tyre demand, more than any price figure. Tyres wear on hours and load cycles, not on what the coal sells for. A fleet running an extra 2.8% of tonnage through the pit is putting more hours on its haul trucks, wheel dozers and loaders, and that shows up in tyre orders whether the coal price is up or down.

With thermal coal still making up more than 60% of national output, the bulk of that tonnage is coming out of thermal-heavy operations, which in practice means a lot of it is centred on Hunter Valley and central Queensland thermal pits alongside the metallurgical mines further north.

Metallurgical coal is the part of the story pointing up

Metallurgical coal exports were 151 million tonnes in 2023-24 and are forecast by the Resources and Energy Quarterly to rise to 174 million tonnes by 2025-26. That is a solid climb in tonnage terms and, in our reading, the clearest single indicator in this data set that Bowen Basin haul fleets are not slowing down. Met coal goes into steelmaking rather than power generation, so it sits on a different demand cycle to thermal, and it is the part of the Australian coal sector currently adding volume rather than easing back.

For a tyre buyer or trader, that distinction is worth keeping straight. A mine's tyre replacement cycle tracks tonnes moved, not the export dollar figure, so a met coal operation growing its export tonnage is a more reliable signal of rising tyre demand than a thermal earnings chart.

Thermal earnings are easing, which is a price story, not a volume story

Thermal coal export earnings were AUD 37 billion in 2023-24 and are forecast to ease to AUD 29 billion by 2025-26, per the Resources and Energy Quarterly. That is a meaningful drop in dollar terms, and it will get read by some as a sign the sector is contracting.

We do not think that follows automatically. Earnings falling while production rises 2.8% is a price effect, coal prices easing off their post-2022 highs, not a sign that thermal mines are cutting truck hours or parking equipment. A mine under margin pressure from a lower coal price is, if anything, more likely to defer capital equipment purchases and run its existing haul fleet harder and longer, which can mean more tyre wear per unit, not less, even if overall spend gets more cautious.

What this means for OTR tyre buyers and stockists

• Treat production tonnage and export volume as the leading indicator for tyre demand, not export earnings, which reflect price cycles rather than truck hours.
• Watch met coal (Bowen Basin) for the more clearly rising trend line through to 2025-26, and thermal (Hunter Valley and central Queensland) for a sector holding volume steady while under earnings pressure.
• Expect margin-conscious thermal operators to keep sweating existing fleets rather than buying new equipment, which in our experience tends to support replacement tyre demand even when capital budgets tighten.
• Coal sits alongside iron ore (our Note 08) as the two pools that between them account for most of Australia's OTR tyre consumption, so a buyer sizing national demand should be looking at both, not just the Pilbara.

Common questions on the numbers

Is coal still worth stocking tyres for if thermal earnings are falling? Yes, in our view. Falling export earnings reflect price, not tonnage or truck numbers. Production is still rising and the haul fleet doing the digging does not shrink just because the coal price has come off a boom high.

Which basin matters most for OTR tyre demand, Bowen or Hunter Valley? Both matter but for different reasons. Bowen Basin is the metallurgical coal engine with export tonnage still climbing, which points to more truck hours. Hunter Valley is thermal heavy and more exposed to the earnings pullback, though the government's own data still has thermal at over 60% of national output.

How does coal compare to iron ore as an OTR tyre market? We rank it second nationally. Our Note 08 covers iron ore, which remains the larger single pool given the scale of Pilbara haulage, but coal is not a minor sideline. It is a genuinely large second leg of Australian OTR demand, not an afterthought.

Does autonomous haulage wear out OTR tyres faster?

Autonomous haul trucks run more hours per day than a manned fleet, and more hours means more tonnes over the tyre. That is the simple mechanical fact behind autonomy's effect on replacement cadence.

Every operator who has moved a haul truck onto an autonomous system tells us the same thing eventually: the truck does not stop as much. No shift changeovers, no meal breaks, no driver fatigue limits. That sounds like an efficiency story, and it is, but for anyone selling or budgeting for giant OTR tyres it is also a wear story. More hours on the ground per truck per day means more tonnes rolling over the same six tyres, and that changes how often those tyres come off the rim.

Source: International Mining, BHP WAIO autonomous and electric fleet report (October 2022). Tyre position figure is a trade proxy calculated by Jewell Tyres from the reported fleet size, assuming six tyres per haul truck.

Why utilisation is the number that matters, not the headcount

When people talk about autonomous haulage they usually talk about safety and labour. As a trader, the number I watch is availability, because availability is what turns into tonnes, and tonnes are what turns into worn rubber. International Mining reported BHP's autonomous fleet at WAIO running at 89% availability, with haulage costs about 20% below the WAIO average. That is not a small gain. An operation squeezing another chunk of runtime out of the same trucks is putting more load cycles through the same tyre casings in the same calendar period.

None of the figures we have here state a tyre wear rate directly, and I am not going to invent one. But the mechanical logic holds regardless of commodity or site: a tyre carries load and generates heat in proportion to hours worked and tonnes hauled, not in proportion to how many people were needed to do it. If autonomy adds hours, it adds wear, full stop.

Scaling it to fleet size, why the numbers get big fast

BHP's WAIO fleet ran 220 haul trucks with a target of around 190, roughly 85%, running autonomously, per International Mining. On our own trade proxy that is about 1,320 tyre positions sitting across the fleet at any one time. Rio Tinto's Pilbara operation was larger again, roughly 400 haul trucks with about 20% autonomous hauling around a quarter of the material, on a 2017 basis of 130-plus autonomous trucks out of about 433, also per International Mining.

• A fleet the size of BHP's WAIO carries well over a thousand giant OTR positions.
• Even a partial shift to autonomy, as at Rio Tinto's Pilbara operation, touches a meaningful slice of that count.
• Small percentage gains in fleet-wide utilisation multiply across a position count that large.

This is the part a buyer sitting in a warehouse or a workshop should sit with. It is not one truck running longer. It is hundreds of tyre positions each running a bit harder, and that compounds into a materially different replacement schedule across a whole site.

What this means for replacement cadence and ordering

In my experience, sites that move trucks onto autonomous haulage tend to find their tyre change intervals arrive sooner than the manned-fleet history predicted. The truck has not changed, the tyre spec has not changed, but the hours worked between changeovers have gone up because the truck is not parked as often. If a site is planning tyre stock on last year's replacement curve, and this year the trucks are running autonomously, that curve is out of date.

My opinion, for what it is worth as a trader and not an engineer, is that any operator moving toward autonomy should treat the transition as a demand-planning event, not just an operations one. Order lead times on giant OTR tyres already run long. If utilisation lifts and nobody adjusts the replacement forecast, the workshop finds itself short at exactly the point autonomy was meant to be delivering its cost advantage.

The flip side is commercially useful too. BHP reported haulage costs about 20% below the WAIO average from the autonomous fleet, per International Mining. If part of that saving is being spent sooner on tyres because the fleet is working harder, that is still a fair trade as long as it is planned for. It only becomes a problem when it is a surprise.

Common questions on the numbers

Does autonomous haulage actually use more tyres, or just the same tyres faster? Based on the figures we have, it looks like the same tyres working harder rather than a different tyre count. BHP's autonomous fleet ran at 89% availability with haulage costs about 20% below the WAIO average, per International Mining. More hours per truck per period means more tonnes over the same six tyre positions, which shortens the interval before replacement, not necessarily the number of tyres fitted at once.

How big a fleet are we talking about when autonomy scales up? BHP's WAIO fleet ran 220 haul trucks with a target of about 190, roughly 85%, running autonomously, per International Mining. On our trade proxy that fleet size represents roughly 1,320 giant OTR tyre positions, which gives a sense of scale for how many positions are affected as a site converts.

Is Rio Tinto's Pilbara operation as far along with autonomy as BHP's WAIO? Not on the figures cited here. Rio Tinto's Pilbara operation ran roughly 400 haul trucks with about 20% autonomous, hauling around a quarter of material, on a 2017 basis of 130-plus autonomous trucks out of about 433, per International Mining. That is a lower target share than BHP's WAIO figure of around 85%, though the two reports are on different bases and years.

Who Actually Makes the Giant OTR Radials, and What Does It Say About Mining Tyre Demand?

Bridgestone and Michelin both sank serious capital into giant radial plants years apart. We read what that tells an Australian OTR buyer about the health of the 49-inch-plus segment.

Every mining tyre buyer in Australia eventually asks the same question when a 51/80R63 quote comes back with a twelve-month lead time: why is this so hard to get. Part of the answer sits a long way from any Pilbara pit, in the capital decisions tier-one makers took years ago about where to build giant radial capacity. Bridgestone's Aiken County plant and Michelin's Lexington expansion are two of the clearest data points we have, and reading them together tells us something useful about how the 49-inch-plus segment we trade in was expected to grow.

Source: Tire Review (Bridgestone Aiken County plant, opened Oct 2014) and Modern Tire Dealer (Michelin Lexington expansion, 2005). USD converted to AUD at an indicative AUD 1 = USD 0.65, rounded.

A billion-dollar bet is not made lightly

In our opinion, the scale of the Bridgestone commitment is the real story here. Tire Review puts the Aiken County facility at about AUD 1.2 billion (US$800 million) on its own, with the wider project reaching AUD 1.85 billion (US$1.2 billion) once support infrastructure is counted. That is not a plant you build to chase a short-term spike in coal or iron ore prices. A 1.5 million square-foot facility on 550 acres, employing 550 people, only gets built when a manufacturer expects decades of demand for 49-inch to 63-inch radials, with headroom already engineered in to go to 73-inch.

We read that future capability line as the most telling detail in the whole announcement. Bridgestone was not just meeting known demand in 2014, it was building for tyre sizes that barely existed in volume at the time. That is a confidence signal about the direction of ultra-class mining equipment, not just the size of the order book on the day the plant opened.

Michelin got there first, and said so plainly

Nearly a decade before Bridgestone's plant opened, Michelin was already expanding at Lexington. Modern Tire Dealer reported a AUD 131 million (US$85 million) investment over five years from 2005, targeted at roughly a 50 percent lift in large surface mining tyre capacity for 57-inch to 62-inch radials. The dollar figure is smaller than Bridgestone's, but the timing matters more than the size. Michelin was reacting to demand it described, through a named earthmover executive, as breaking every record, years before the current wave of Pilbara and Latin American copper expansions that Australian buyers now take for granted.

Put the two investments side by side and you get a pattern rather than a single data point: two separate tier-one makers, on two separate timelines, both committing serious capital to the same narrow slice of the tyre market. That is a stronger signal than either investment read alone.

What this means for buyers of 49-inch-plus tyres

Our take, as a trader working this segment day-to-day, is straightforward.

• Capacity in giant radials is deliberately scarce because the plants are expensive and slow to build, so lead times are structural, not a temporary supply hiccup.
• Tier-one manufacturers do not size these plants for a five-year horizon. If Bridgestone engineered in headroom to 73-inch back in 2014, that is a long-dated bet on haul truck and shovel sizes continuing to climb.
• Buyers should not expect a sudden glut of 49-inch-plus stock. These investments raise the ceiling on supply, they do not flood the market.
• The used and remanufactured market we operate in benefits directly from this dynamic. When new-build capacity is tight and expensive to expand, well-maintained secondary units become a more sensible part of a mine's tyre strategy, not a fallback.

The honest limits of this read

We are not tyre engineers and this is not procurement advice. These two plant investments, one from 2005 and one opened in 2014, do not tell us anything about current spot availability or this year's pricing. What they do tell us, in our opinion, is that the manufacturers with the deepest pockets in this industry looked at the 49-inch-plus segment twice, a decade apart, and both times decided it was worth nine or ten figures of capital. That is the kind of signal a buyer can factor into long-term fleet planning, even if it says nothing about next month's quote.

Common questions on the numbers

Does a tier-one plant investment mean prices will fall? Not necessarily. In our opinion, added capacity mostly means fewer shortages and steadier lead times over the medium term, not cheaper tyres. Giant radials remain a complex, capital-heavy product and pricing follows raw materials and freight as much as plant output.

Should Australian buyers wait for more capacity before ordering? In our opinion, no. These investments were committed years ago and lead times on 49-inch-plus radials are already long. We would keep ordering on the buyer's normal cycle rather than betting on a supply glut that these figures do not point to.

Why does it matter who builds these tyres? Because the giant radial segment has very few manufacturers with the plant, tooling and metallurgy to make 49-inch to 63-inch radials properly. Knowing which tier-one makers committed capital, and when, is a reasonable proxy for how much they expect this segment to keep growing, per Tire Review and Modern Tire Dealer.

Why has Yokohama bought up Goodyear OTR, Trelleborg and Alliance?

Yokohama Rubber has spent the best part of a decade buying its way into a dominant position in giant OTR and off-highway tyres. We look at what deals worth roughly AUD 6.6 billion combined mean for anyone buying earthmover rubber in Australia.

Over the past decade Yokohama Rubber has quietly assembled one of the biggest off-the-road tyre portfolios in the world, buying Alliance Tire Group in 2016, Trelleborg Wheel Systems in 2022 and Goodyear's OTR business in 2024. Three separate deals, three separate press releases, but one buyer at the end of it. For anyone in Australia sourcing giant earthmover tyres, it is worth understanding what that concentration actually changes, and what it does not.

Source: Yokohama Rubber (Trelleborg acquisition release) and Goodyear (OTR sale release). USD and EUR converted to AUD at indicative rates of AUD 1 = USD 0.65 and AUD 1 = EUR 0.61 (EUR 1 = AUD 1.65), rounded.

Three deals, one direction of travel

In our opinion the pattern matters more than any single transaction. Yokohama did not stumble into off-highway tyres, it built a position deliberately. Alliance in 2016 gave it agricultural and industrial radials for about AUD 1.81 billion (US$1.179 billion). Trelleborg Wheel Systems in 2022 added another layer of ag and industrial capacity at an enterprise value Yokohama itself put at about AUD 3.4 billion (EUR 2,040 million), though Rubber News reported the same deal at roughly US$2.3 billion. Then in 2024 Yokohama picked up Goodyear's entire off-the-road tyre business, the bit that actually makes giant earthmover and mining tyres, for about AUD 1.39 billion (US$905 million cash).

Add those three together and you get a company that now sits across ag, industrial and giant OTR simultaneously, under brands that used to compete against each other on price and availability. That is the structural shift buyers should be tracking, not any one deal in isolation.

What it means for pricing

Fewer independent giant OTR manufacturers generally means less price tension at the top of the market. When Goodyear OTR, Trelleborg and Alliance were separate commercial operations, a buyer with a big mine site tender could play one off against another. With all three now reporting into the same parent, that leverage narrows, even if the individual brands keep separate sales teams and separate pricing on paper for now.

We are not saying prices will spike overnight. Yokohama has every commercial reason to keep the acquired brands running as they were in the short term, it paid good money for the customer relationships and the distribution networks that came with each deal. But the medium-term direction, in our opinion as traders, points to less independent pricing competition at the giant OTR end of the market than existed five years ago.

What it means for availability

Consolidation also concentrates manufacturing risk. If a plant outage, a raw material shortage or a logistics disruption hits one part of the combined Yokohama group, it can now ripple across brands that buyers previously treated as independent alternatives. A shortage that used to be a Goodyear OTR problem, solvable by switching to Trelleborg or another supplier, is increasingly a Yokohama group problem across the board.

• Buyers who single-source from one of these three brands should treat that as effectively single-sourcing from Yokohama as a whole.
• Genuine independent alternatives (suppliers outside the Yokohama umbrella) become more valuable for spreading risk, not less.
• Lead times on giant OTR sizes are worth watching closely as integration of the Goodyear OTR business (announced 2024) works through supply chains.

Where this leaves the independent buyer

None of this is a reason to panic, and it is not a call to abandon any of these brands, all three still make good tyres. It is a reason to widen the supplier list rather than narrow it. In our opinion, the sensible response for an Australian buyer is to actively maintain relationships with tyre sources outside the Yokohama group, alongside the Yokohama-owned brands, so that a single corporate decision (on plant allocation, on pricing strategy, on which markets get priority supply) does not become your whole procurement risk.

It is also worth keeping half an eye on further consolidation. Three major acquisitions in eight years by one company is not a pattern that necessarily stops at three.

Common questions on the numbers

Does Yokohama now own Goodyear, Trelleborg and Alliance outright? Yokohama bought Goodyear's off-the-road tyre business (not all of Goodyear) for about AUD 1.39 billion (US$905 million), announced in 2024, according to Goodyear. It separately bought all of Trelleborg Wheel Systems in 2022 and all of Alliance Tire Group in 2016.

Will this push OTR tyre prices up in Australia? We cannot say for certain, this is our trade opinion rather than a forecast. Fewer independent giant OTR manufacturers generally reduces price tension at tenders, so we think it is a trend worth watching rather than something to ignore.

What should a buyer do about it now? In our opinion, keep at least one supplier relationship outside the Yokohama-owned brands (Goodyear OTR, Trelleborg, Alliance) so a single company's decisions on plant allocation or pricing do not become your entire supply risk.

Why did Bridgestone buy Otraco's OTR tyre management business?

Bridgestone completed its purchase of mine site tyre manager Otraco on 1 December 2021. It is a signal that a tier-one manufacturer now wants to own the service around the tyre, not just the tyre itself.

On 1 December 2021 Bridgestone finished buying Otraco, an OTR tyre management specialist working mine sites in Australia, Chile and South Africa, from Downer EDI for about AUD 79 million (about JPY 6.6 billion), according to Bridgestone Corporation. On the surface that is a tyre company buying a services firm. Underneath it, it is a tier-one manufacturer deciding that selling rubber is no longer enough, and that the money is in managing the fitment over its working life. For an independent trader operating on the same mine sites Otraco services, that is worth sitting up for.

What Bridgestone actually bought

Otraco is not a tyre brand and it does not manufacture anything. It is a tyre management business that goes onto a mine site, monitors the fleet's tyres, tracks wear and pressure, and decides when a tyre gets rotated, repaired or pulled. It does this through its own system, Otracom, according to Bridgestone Corporation. Bridgestone did not need Otraco to make better tyres. It bought Otraco to sit inside the customer relationship at the point where the buying decision actually gets made, on site, fleet by fleet.

That is a different kind of asset to a compounding plant or a factory. It is people, contracts and a data system embedded in a mine's operation. Buying it for about AUD 79 million (about JPY 6.6 billion) from Downer EDI, as Bridgestone Corporation reports, tells you the manufacturer sees more durable value in owning that relationship than in simply winning the next tender for tyres.

Why this is a bigger deal than another supplier swap

Independent traders and fitters have long lived in the gap a tyre manufacturer leaves behind: nobody at head office in Tokyo or Osaka is walking a haul road at 2am deciding whether a rear dual needs pulling. Management, monitoring and site presence has mostly been done by independents, by mining contractors themselves, or by specialist firms like Otraco that stayed brand neutral.

Bridgestone owning that layer changes the shape of the relationship. A mine that signs up to Otraco's management service is now, in effect, closer to a single brand tyre programme run by the manufacturer that also builds the tyre. Bridgestone Corporation frames this as extending beyond selling the tyre into managing it on site, which is a polite way of describing a manufacturer moving up the value chain into the part of the business an independent trader used to own.

The competitive read for us

• Otraco operates in Australia, Chile and South Africa, three of the biggest hard rock and open cut mining regions in the world, per Bridgestone Corporation, so this is not a niche play, it covers our home turf directly.
• A tier-one owning the management layer can bundle tyre supply, monitoring and reporting into one contract, which makes it harder for an independent to win the management piece even where our tyre pricing and fitment advice are competitive.
• It is also an opportunity. Mines that do not want to be locked into a single manufacturer's management system may value an independent's neutrality more, not less, once they see a competitor consolidating the whole chain under one roof.

What we will be watching

The number worth remembering is the AUD 79 million (about JPY 6.6 billion) Bridgestone paid, per Bridgestone Corporation, because it puts a dollar figure on how much a tier-one is willing to spend to own the service layer rather than compete with it. Note 13 covers manufacturer consolidation more broadly, and this Otraco purchase reads as one instance of the same pattern, a name brand buying its way into a business it used to leave to others.

Our own view, and this is opinion rather than any kind of engineering or procurement advice, is that mine operators should keep asking who actually owns the tyre management data and the fitment decisions on their site, and whether that arrangement still gives them room to shop the market. That question gets more pointed, not less, as more of the chain sits under one manufacturer's roof.

Common questions on the numbers

How much did Bridgestone pay for Otraco? About AUD 79 million (about JPY 6.6 billion), according to Bridgestone Corporation, for the acquisition completed on 1 December 2021 from Downer EDI.

What does Otraco actually do? Otraco manages OTR tyres on mine sites in Australia, Chile and South Africa, using its own tyre management system called Otracom, per Bridgestone Corporation.

Why does this matter to an independent OTR tyre trader? It shows a tier-one manufacturer moving beyond selling tyres into owning the on-site management relationship, which is territory independents and site-based specialists have traditionally occupied.
