The three center ribs keep the tire's road contact at all times, which improves the steering responsiveness and driving stability. The steering becomes quicker and more accurate in its responsiveness to the driver's commands, while the structure is stabilized against the driving pressure. This enables the driver to confidently control the vehicle in all weather. The parallel lateral grooves and additional siping detail upgrade the braking distance. Aided by the silica compound, they create friction at the moment of braking, shortening the braking distance significantly and ensuring a secure high speed performance.
