The improved contact with the road surface increases the steering responsiveness and the driving stability. In other words, the model is quicker and more precise in its response to the driver's commands, while the structure is stabilized against the driving pressure affecting the tire. The optimal shoulder tread pattern enhances the cornering and maneuvering ability. The stabilized pattern keeps the road contact and heightens the number of biting edges gripping the road surface to increase the high speed cornering power. The stabilized construction enables the tire's safer high speed performance, which upgrades the high speed driving capability and safety.
