The two narrow center ribs and the large shoulder tread blocks keep the tire's road contact at all times, enhancing the steering responsiveness, driving stability, and cornering capability. In this manner, the steering becomes faster and more precise, while the tire's structure is stabilized against the driving pressure affecting it. The shoulder tread blocks heighten the number of biting edges that firmly grip the road surface and boost the cornering ability and power. The upgraded controllability ensures a safer all season performance.
