The Dynapro HP RA23 is designed from a silica enhanced compound molded into an aggressive tread pattern for exceptional off-road performance, enhanced durability and all-season traction, even in light snow. The solid center rib block and large outer shoulders provide responsive steering, great handling and outstanding dry braking. The stiff lateral and center tread blocks combined with the optimal kerf design reduces noise levels as well as improves durability. The 2-step graduated groove technology is designed to increase hydroplaning resistance, and deliver improved wet grip when combined with the semi-grooves. The internal construction features jointless cap ply and high-strength steel belts for increased stability at high speeds and long wear.
