Ironman I-181 tires: heavy-load 22.5-inch fitments built to carry weight
Ironman I-181 tires are built for big-rim, high-load work, and the sizes we carry sit squarely on the 22.5-inch rim diameter. This page covers this one model — the I-181 tread — so you can see the exact sizes we stock, the ratings on those sizes, and where the pricing lands before you order.
The sizes we carry
Every I-181 fitment we stock mounts on a 22.5-inch rim diameter. The representative sizes we carry are 12R22.5 and 255/70R22.5. Treat this as the sizes we stock rather than the model's full size range — it's what's on hand and ready to ship. For a concrete example, the 255/70R22.5 in a 140/137M service rating is the lightest-priced option in the group, while the 12R22.5 rated 152/149L sits at the top. A 10.00R20 in 146/143K is also available.
Ratings on file
Across the I-181 sizes we carry, speed ratings run L and M — deliberately conservative, matched to hauling rather than speed. Load indexes span 137 through 152, with load ranges H and J. Service descriptions show up as combinations like 140/137M, 146/143K and 152/149L, which pair the single- and dual-wheel load capacities with the speed letter. Those numbers tell you these tires are meant to carry serious weight.
Price band and who it suits
I-181 pricing runs from about $366 to $598 per tire depending on size and rating. That puts it in reasonable territory for tires built to this load class — a sensible pick if you run heavy loads on 22.5-inch fitments and want dependable capacity without a premium sticker.
If your vehicle runs smaller rims, several stablemates cover different ground: the Radial A/P and the light-truck RB Metric serve different uses, while the All Country HT and rugged All Country M/T are aimed at trucks and SUVs. You can see the whole lineup on the Ironman brand hub or browse everything under tires.
