It combines the heat-resistant compound, the stronger structure, and the close and constant surface contact improves the high speed performing power. The compound prevents heat build-up along the tread area, easing the pressure off the tire. On the other hand, the construction keeps the ideal tire shape under the high speed pressure, while the road contact ensures even pressure circulations. These improvements enable the tire to securely perform at its best high speed ability, optimizing the tire's racing application.
