Having achieved legendary status, the Race King heralded the advent of the current Continental "King" range. When its dry the Race King is as fast and provides as much traction as can be asked, and rolling resistanace rivals that of many road tires. Tires with Black Chilli Compound deliver a performance that had not yet been reached. Compared to silicia tires, tires using black chilli provide 26% lower rolling resistance, 30% higher grip, and 5% longer miliage. Pro Tection tubeless-ready performace previously stood primarily for sidewall protection, but our latest generation combines a unique casing ply with a UST-style bead for Conti's Revolution Tubeless Ready design. An additional layer of rubber coated, high strength nylon the spans the complete width of the tire, not only additional durabilty, but also serves to maintain air tightness in a tubeless-ready configuration.
