RP Advanced Mobile Systems SOF Series II 8-Ply ATV Run Flat Tires feature a bias and radial overlap proprietary process that delivers reinforced sidewall structure. Added bead-ring protection minimizes degradation to the sidewall flex and improves acceleration without sacrificing engine output. Aggressive, multi-directional tread makes them versatile in rugged conditions and reduces the need for mixed vehicle front/rear tires. Wrapped-tread design, hard-compound rubber and thick sidewalls provide full protection from rough terrain. Wide contact patches reduce driver feedback while maintaining traction. Validated to operate flat for 50 miles at 40 mph and have a 900-lb. load rating so you can climb rocks and roll over brush with all your gear. Imported. Sizes: 26" x 9" x 12", 26" x 9" x 14"(not shown).
