Questions buyers ask

What do TRA codes like E4, L5 and G2 mean?

TRA codes describe what an OTR tyre is built for. E is earthmover haulage (dump trucks), L is loader and dozer, G is grader. The number is the tread type: 1–2 ribbed or traction, 3 rock, 4 deep-tread rock, 5 extra-deep tread for severe cut resistance.

What do the stars (★) mean?

Stars are the strength / load rating of a radial OTR tyre: one star (★) is the lighter rating, two (★★) and three (★★★) carry more load at the same pressure. Match it to your machine's specification.

Can you quote new, used and retread?

Yes. Verified stock gets an instant quote; for anything else we check our supplier network and come back with options — new, used or retread, as you prefer.
