OTR tyres for the CAT 992K

The current-generation Caterpillar 992K wheel loader runs 45/65R45 L-5 tyres at standard configuration. This is the fitment reference, sizes, brands, compounds, and selection considerations.

/ Machine context

The CAT 992K production loader.

The Caterpillar 992K is the current production wheel loader in the 992 series, the workhorse mid-large loader for Australian mining operations. Operating weight ~94,000 kg, bucket capacity 12.3 m³ standard, engine 596 kW. Designed for high-production loading of haul trucks at the digger face.

The 992K succeeded the 992G in the mid-2010s. The earlier 992D and 992G generations ran 33.5R39, a different size altogether. If sourcing for legacy 992 fleet, confirm the actual machine generation before ordering tyres.

Standard tyre fitment

Size: 45/65R45 · TRA code: L-5 · Construction: Radial · Star rating: ★★

The 45/65R45 L-5 is the standard fitment across both axles. All four tyres on a 992K are typically the same size and TRA code. Heat-resistant compound is standard for Pilbara iron ore and hot-ambient applications; cut-resistant compound is the preference where the cycle is shorter and ground is more abrasive.

Patterns worth considering / our opinion

  • Tier-one heat-resistant: Bridgestone VRDP (default), Michelin XLD D2 L-5, Goodyear RL-5L
  • Tier-one cost-competitive: Yokohama RL5K+ (strong residual value)
  • Mid-tier (for secondary fleet 992K): BKT Earthmax SR468, Aeolus AL57

TKPH considerations

The 992K running standard Pilbara iron ore cycles typically requires a tyre rated for 750-950 TKPH. Specific calculation depends on cycle length, ambient temperature, and load consistency. Adjust for the Pilbara summer derating (+15-20% required TKPH above ambient-corrected baseline).

A safety margin of 10-20% above calculated required TKPH is normal practice. The free TKPH calculator handles the corrections.

/ Before you act Figures above are indicative for a typical configuration only, and the pattern shortlist is our opinion as an independent trader, not a professional recommendation. Actual required TKPH and fitment depend on your specific machine build, cycle and site, confirm against manufacturer data, and for a fleet or contract decision, a qualified engineer. This is general reference and opinion, not engineering advice.

Common cycle types

  • Production loading at the digger face, high-frequency short cycles, heat builds quickly. Heat-resistant compound preferred.
  • Stockpile and reclaim, variable cycle length, mixed material. Standard compound often acceptable.
  • Rehandle and rehab, secondary tasks, lighter duty. Mid-tier mid-spec acceptable.
