Improve Tire Life with GMI

Marathon is proud to be partners with GMI Wheels to provide Off-Highway wheel and rim assemblies for the mining and resource industries.

GMI has over 150 years of combined experience in the industry and understands how to produce wheel and rim components that increases safety of the wheel assembly and improves tire life.

Smooth Surfaces

GMI Wheels use a machining process to make 100% round and smooth wheels, eliminating the need for damaging knurling. These wheels transmit high torque without damaging the tire and have a longer lifespan than conventional wheel competitors. This reduces tire costs and waste.

Avoid Tire Bead Damage

Other wheel manufacturers add knurling (rough impressions) where the tire bead seats, claiming this helps the tire seal. In reality, it’s put in place to compensate for outdated manufacturing methods and poor tolerances. Knurling damages the tire bead and drives up your tire costs.

GMI wheels provide a fully machined & truly round bead surface, free from knurls. This provides a proper platform for the tire to seat and seal, extending tire life and driving down your tire costs.

Tire Life and Air Seal

Conventional OTR wheels are rolled and welded, creating an imperfect shape that often isn’t aligned and perfectly round. To compensate, knurling is added to the bead seating areas, chewing into the tire bead.

Knurling found on competing wheels prematurely damage tire beads, rendering them unuseable even if the tread is in good condition

GMI Wheels: Perfectly aligned

GMI Wheels products use a machining process, making them 100-percent round and smooth for uniform contact, achieving the best possible tire fitment, air seal and component fitment.

Machining ensures critical components, such as lock rings, bead bands and flanges, fit together seamlessly to maintain a class-leading air seal.
