The better road contact evenly distributes the driving pressure across the entire tread area, on the center and the shoulder area. The equally spread out forces of the high speed acceleration, cornering and braking prevents irregular tread wear from forming on the tire's surface. This also maximizes the road contact which enhances the steering responsiveness and driving stability. The constant road contact secures the tire against the driving pressure and offers a quick and precise steering responsiveness to the driver's commands.
