The directional tread design's center rib pattern closely follows the road surface at all times, which 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 commands, while the structure is stabilized against the driving pressure affecting the model. The model's reinforced internal structure maintains the ideal shape under the high speed pressure. In this manner, the tire does not deform during its high speed performance, enabling the vehicle to perform at its greatest high speed capability.
