The outer shoulder's tread design increases the number of biting edges that firmly grip the road surface in all weather. The higher number of biting edges ensure a more secure cornering ability and power, enhancing the tire's maneuvering capability significantly. The tread design's three center ribs also maintain their road gripping ability. They boost the steering responsiveness, by making it faster and more accurate, and the driving stability, by securing the tire's structure against the driving pressure.
