This asymmetric tread design and road contact boost steering responsiveness. In other words, it improves the steering response time and accuracy to the driver's commands, while the structure is secured against driving pressure. In this manner, the siping detail and the large shoulder blocks also increase cornering and maneuvering even at high speeds. The shoulder blocks grip the road surface all the time, while the siping detail shortens the braking distance. As a result, this model guarantees the drivers full control over the vehicle.
