Product Info

GEN 2 I-31M

Ironman GEN 2 I-31M tires are a rugged commercial mixed-service option for fleets and owner-operators who need an all-position replacement built for on/off-highway duty. Tire Crew can help you shop this model when you want a straightforward, spec-matched tire with a narrow catalog footprint.

The approved size is 315/80-22.5, listed with Load Range L, 161K, and a maximum inflation pressure of 130 psi. Ironman positions this model as the replacement for the I-301, making it a useful choice for buyers maintaining existing mixed-service truck specs.

For durability-focused commercial use, the GEN 2 I-31M is designed around deeper 22/32" tread depth, an improved heat-resistant compound, and features such as zig-zag biting grooves, stone ejectors, a jagged shoulder design, and a curb guard.
