The tread features a solid center rib with curved edges, directional tread blocks in the center tread and large shoulder tread blocks. They ensure exceptional controllability by improving the steering responsiveness and driving stability. In other words, the steering becomes faster and more precise in its responsiveness to the driver's commands, while the tire's structure is stabilized against the driving pressure affecting it during the drive. The larger shoulder tread elements heighten the number of biting edges that grip the road surface during cornering and maneuvering. In this manner, the directional tread also enables the tire to perform to its highest capability.
