The tread design's ribbed pattern features closed shoulder ribs that keep the tire's road contact at all times. In this manner, the model improves the tread life by evenly circulating the driving pressure along the tread area. The force of acceleration, braking and cornering is equally spread out on the tire's surface, which actively prevents the formation of irregular wear along the tread area. The longer lasting even tread wear greatly extends the tire's usability and tread life.
