It helps the tire to closely follow the road, which boosts steering responsiveness and driving stability. As a result, the tire is quicker and more precise to the driver's commands, while the structure is secured against the driving pressure affecting the tire. On the other hand, the close road contact also boosts the tire's high speed durability. It allows the tire to ease the pressure off the tread area, which prevents heat build-up, while also keeping the ideal tire shape at all times. This combination ensures the tire's safe high speed performance.
