The tread's high void ratio and open shoulder pattern work together to disperse mud and snow and to eject rocks stuck between the tread elements. In this manner, the stone retention does not harm the tire's casing by drilling rocks into the tread. It also maintains a clean footprint and ensures the tire's contact with the road and terrain surface at all times. As a result, the tire improves its performing capability by guaranteeing a secure grip on the road surface.
