With th Speed King 2.2 tire, the lightly raised outer lugs give grip when cornering allowing high speeds. While the center area is made up of flat, wedge-shaped lugs which keep the rolling resistance low and provide plenty of straight line traction to rear wheel. 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.
