The footprint maintains the road contact at all times, while the secure winter traction ensures a better driving safety. This enables the tire to upgrade 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. The shoulder block placement, with the siping detail, firmly grips the road surface at all times. This enables the tire to improve the maneuvering and cornering capability. The high-density zigzag sipe placement manages to shorten the braking distance. They generate friction at the moment of braking, greatly enhancing the braking capability.
