They boost steering response time and precision, while the structure is secured against the driving pressure affecting it. At the same time, the siping detail and the close road contact shorten the braking distance. The strengthened internal structure and the heat-resistant compound improve the high speed drive. In this manner, the construction does not allow the tire to deform under pressure, while the compound prevents heat build-up along the tread area. As a result, it guarantees excellent high speed performance.
