Ironman Tires has introduced four new tires to its I-Series Gen 2 lineup. The new models— I-31M, I-42W, I-28D and I-52A— join the previously launched I-19A, I-37D, I-48T and I-61S.

The new tires feature upgraded designs and compounds aimed at improving durability, traction, and fuel efficiency, the company said in a news release. Ironman also announced an extended Peace of Mind Warranty, now offering six years of coverage for defects in workmanship and materials, as well as a casing allowance for two retreads.

The I-28D is designed as a regional and long-haul drive tire, offering advanced compounds that reduce rolling resistance and increase fuel efficiency. Its 28/32nds tread depth, wider contact patch, and zig-zag sipes provide improved traction and stability in all weather conditions.

The I-31M serves as a versatile, all-position tire for on- and off-highway use, featuring a deeper tread for increased mileage and durability, as well as protective stone ejectors and a curb guard.

For heavy loads, the I-42W wide-base all-position tire is suited for mixed-service applications, with deep treads and a semi-open shoulder design to enhance traction and drainage.

Meanwhile, the I-52A is engineered for high-scrub regional environments, offering a wider tread for even wear and wavy outer grooves to improve tear resistance.
