The asymmetric tread design maintains the surface contact throughout the drive, which improves the steering responsiveness and the driving stability. This results in a quick and precise steering response, while the structure is secured against the driving pressure. The stronger structure with the steel belt and nylon cap construction enable the tire to improve the high speed durability. The stronger compound keeps the optimal flexibility, preventing heat build-up along the tread area. These enable the tire to greatly upgrade the high speed performing power.
