The solid center rib of the directional tread design maintains the surface contact while the tires are in motion, which boosts the steering responsiveness and the driving stability during the performance. The strengthened shoulder block pattern provides additional biting edges gripping the road surface which improves the cornering and maneuvering capability. The heat-resistant compound and the rounded tread pattern work together to improve the high speed durability. The compound prevents heat build-up, while the tread allows the model to keep the ideal tire shape. This combination enables the tire to securely perform at its utmost high speed capability.
