This is achieved with the wear-resistant compound and the stable footprint. They work together in order to prevent irregular and premature wear along the footprint. Stronger rubber materials decrease the overall treadwear rate, while the tread's even pressure circulation avoids irregular wear. Additionally, the self-cleaning nature of the tread avoids stone retention. The groove bottom knobs eject rocks stuck in the grooves, resisting stone drilling. These improvements boost the tire's overall usability.
