The better road contact helps to upgrade the steering responsiveness and the driving stability, ensuring the driver's better control over the vehicle. This promotes a quicker and more precise steering response to the driver's commands, while the structure is secured against the driving pressure affecting the tire. The groove pattern helps to shorten the braking distance by generating friction between the tire and the road surface. This greatly boosts the tire's braking power and performing ability. The maintained ideal tire shape and the heat-resistant compound also manage to enhance the high speed durability. They prevent pressure accumulation along the tread area and keep the ideal tire shape under the pressure, enabling the tire to securely perform at its utmost high speed ability.
