Yokohama introduced the new RY637 MSC steer-axle tire as a solution to the irregular wear problems of steer-axle tires.
Yokohama’s Maintenance Saving Concept (MSC) is geared to controlling the pressure on the tread as the tire rolls. The Stress Wear Control Groove (patent pending) reduces the contact pressure at the tread edge. This results in increased resistance to shoulder step-down wear. The tire also has patents pending for its design to isolate heavy pressure on the rib and reduce the contact pressure on the inner rib edge.
An ultra-wide top steel belt provides uniform stiffness across the tread face of the tire. On conventional steel radials, the top belt is typically more narrow, Yokohama says. In the RY637 MSC, the top belt is extended to the shoulder of the tire to add stiffness to the face of the tread.
The RY637 MSC comes with a six-year limited warranty through threeretreads plus an increased casing allowance.
