The tread's optimal pattern features staggered and siped tread blocks, open shoulders, and a high void ratio, which enhance soft and loose terrain performance. They increase the tire's grip on such terrains, while also offering a constantly clean footprint. The tread elements eject rocks and eliminate mud and snow stuck between the tread elements. In this manner, they maintain the tire's surface contact at all times, actively resisting stone retention from harming the casing.
