The Sumitomo ST 528 tire is engineered for highway and off-road use. It features the proven rib design that minimizes rolling resistance and boosts stability. In wet conditions, the wide grooves drain water to improve safety. Special rust inhibitor compounds coat the four steel breakers to prevent rust. The optimized groove shape combines with stone ejector buttons to prevent stone retention for a longer casing life. The deep tread ensures superb grip on off-road surfaces as well as longer service.
