The center and shoulder block ribs keep the tire's road contact at all times, which effectively boosts the steering responsiveness and driving stability. In this manner, the steering becomes faster and more precise in its responsiveness to the driver's commands, while the structure is stabilized against the driving pressure affecting the tires during the drive. The shoulder tread blocks increase the number of biting edges that firmly grip the road surface during cornering and maneuvering. The tread design's S-shaped siping detail manages to shorten the braking distance by creating friction at the moment of braking. As a result, the tire's controllability is safer and effortless.
