The tread's continuous center ribs closely follow the road surface and maintain the tire's surface contact in summer. As a result, the tire upgrades the steering responsiveness and the driving stability. In other words, the steering becomes faster and more precise in its response to the driver's instructions, while the structure is stabilized against the driving pressure affecting the model. The stronger construction manages to keep the optimal tire shape under the high speed pressure. This, along with the compound's excellent heat resistance, enables the tire to securely perform at its greatest high speed capability and power, guaranteeing the driver's full control over the vehicle during its high speed performance.
