The center rib maintains the surface contact at all times, upgrading the steering responsiveness and driving stability. In this manner, the tire promotes great steering response time and accuracy to the driver's commands, while the structure is secured against the driving pressure. The detailed shoulder block pattern firmly grips the road surface with extra biting edges, boosting the cornering ability and power. The high-density siping placement firmly grips the road surface, generating friction at the moment of braking. This greatly shortens the braking distance as well, promoting better performance.
