The high void ratio and the directional tread lug placement prevent mud and snow from getting stuck between the tread elements and blocking the tire's surface contact. As a result, the model provides a safer performance by ensuring constant terrain contact. The dimpled lugs avoid stone retention. The dimples eject rocks stuck in the lugs to resists stone retention from drilling into the tire's casing and damaging the tire. In this manner, the model promotes a safer performance.
