- Larger tire footprint. Combine the D8's large contact patch with the tree-like central spine and you get all the grip, stability, high-speed control and confident cornering you could ask for. - Grip-enhancing compound. High silica formula promotes fast braking and responsive handling, especially in wet conditions. - Wet grip grooves. Twin longitudinal grooves with 3-D groove walls evacuate water and resist hydroplaning. - Noise reducing design. Variable pitch patterns with 2-in-1 alignment reduce noise levels at high speeds.
