Ironman GEN 2 I-31M Tires

Product Info

GEN 2 I-31M

Ironman GEN 2 I-31M tires are a commercial mixed-service all-position option for fleets and owner-operators who need a rugged replacement for on/off-highway work. Discount Tire & Brake Inc. can help you shop this model when durability, traction, and spec-matched sizing matter most.

This lineup is intentionally narrow, with one approved size: 315/80-22.5. It is listed with Load Range L, 161K, and a maximum inflation pressure of 130 psi, so the key comparison points are load capacity and exact fitment. The GEN 2 I-31M also replaces the Ironman I-301, making it a practical choice for shoppers maintaining an existing mixed-service truck spec.

Ironman positions this tire for severe-condition reliability and mixed-service durability, with a deeper 22/32" tread depth, improved heat-resistant compound, zig-zag biting grooves, stone ejectors, jagged shoulder design, and curb guard. If you need help choosing a commercial replacement or want to review service options, Discount Tire & Brake Inc. can support your search alongside Shop Tires and Schedule Appointment.
