The maintained surface contact enhances the steering responsiveness and the driving stability, as the center rib closely follows the road contact. As a result, it offers a quicker and more precise steering response, while the structure is secured against the driving pressure. The shoulder block pattern improves the cornering ability with the use of extra biting edges. The strengthened internal structure and the heat-resistant compound elements work together to boost the high speed durability. They prevent heat build-up across the tread area, while keeping the ideal tire shape under the high speed pressure. This combination allows the tire to securely perform at its utmost high speed capability.
