The high void ratio between the lugs and the grooved lug centers eliminate mud, snow and rocks from the tire's footprint. This keeps the footprint clean at all times, which enhances the tire's performing capability. It also resists stone retention from harming the tire's casing, while avoiding cuts, punctures and bruises caused by other debris. The durable construction keeps the optimal tire shape, preventing its deformation under the driving and load pressure affecting the model, to improve the year round driving safety.
