The tread design features a continuous solid center rib and isolated shoulder tread blocks that keep the tire's road contact at all times. The center rib's better road contact increases the steering responsiveness and driving stability, in other words the tire's overall controllability. In this manner, the steering becomes faster and more precise in its responsiveness to the driver's instructions, while the structure is stabilized against the driving pressure affecting it during the drive. The shoulder tread blocks boost the cornering ability and power by heightening the number of biting edges that firmly grip the road surface during maneuvering. The safer controllability and cornering capability enable the driver to confidently control the vehicle.
