The better road contact allows the tire to enhance the steering responsiveness and the driving stability. In other words, the tire is quicker and more precise in its response to the driver's commands, while the structure is secured against the driving pressure affecting the tire. The shoulder block pattern, with the siping and notch placement, upgrades the cornering and maneuvering ability by utilizing additional biting edges at all times. The siping placement across the tread area shortens the braking distance, by generating friction at the moment of braking.
