The symmetric ribbed tread design and the stronger, wear-resistant compound manage to avoid irregular and premature tread wear along the tread area, by ensuring even pressure distribution and resisting accelerated tread wear. As a result, the tire improves the tread life and usability. To prevent external damage from shortening the model's service life, the grooves feature special rock ejecting knobs. These knobs eliminate rocks stuck between the tread elements, before they can drill into the casing and harm the tire, actively preventing stone retention. The prevention of stone retention ensures the tire's excellent performing ability.
