The continuous center rib of the tread pattern boosts the steering responsiveness and the driving stability. In other words, the surface contact upgrades the steering response time and accuracy to the driver's commands, while the structure is stabilized against the driving pressure. The shoulder block placement, with the siping placement, enhance the cornering ability with extra biting edges. The siping placement creates friction between the tire and the road surface in order to shorten the braking distance, upgrading the braking power and offering a secure performance. The heat-resistant compound and the durable structure enable the tire to perform at its utmost high speed capability. This allows the tire to safely boosting the high speed durability and performing ability.
