Tires with DuraSkin® sidewall protection are designed to withstand the rigors of riding. They are used in the toughest conditions. On delivery bikes, tires slide along curbs; on touring bikes, they cross continents without wearing out. In racing, they must endure grueling events like Paris-Roubaix. The high-quality polyamide fabric protects the tire casing from the harshest conditions. These tires are distinguished by their brown sidewalls.
