These tread elements optimize the surface contact on versatile terrain surface conditions, upgrading the soft, loose, and uneven terrain grip. This increases the forward motion on versatile terrain surface conditions, enhancing the deep mud and loose terrain traction. The self-cleaning tread design allows the tire to eliminate mud, snow, and rocks stuck between the tread elements. As a result, mud and snow do not block the surface contact. It also avoids stone retention from harming the casing.
