The maintained surface contact of the ribbed tread design greatly improves the pressure distribution across the tread area. This model also uses the DuPont Kevlar compound, which is a lightweight material which helps to strengthen the tire. This strong compound elements optimize the rubber flexibility in versatile temperatures, slowing the treadwear rate down. This maximized rubber volume also protects the tires from damage, such as punctures, tearing, or cutting. The combination of these two elements significantly boosts the tire's service life.
