The directional tread's solid center rib maintains the ideal surface contact throughout the model's performance. In this manner, the tire boosts the steering responsiveness and the driving stability. The model becomes quicker and more accurate in its response to the driver's commands, while the structure is stabilized against the driving pressure affecting the model. The reinforced construction maintains the ideal tire shape under the high speed driving pressure affecting it. The optimized shape increases the performing capability and power, enabling its best high speed durability.
