The tread pattern's ribbed design is capable of maintaining the tire's road contact at all times. The constant road contact improves the steering responsiveness and driving stability. As a result, the steering responsiveness to the driver's commands is faster and more precise and the structure is stabilized against the driving pressure affecting the tires during the drive. The closed shoulder design increases the tire's road contact area, which upgrades the cornering and maneuvering ability and power, guaranteeing a safer performance.
