The tread's optimal shoulder ribs closely follow the road surface at all times, which significantly boosts the steering responsiveness and the driving stability. The steering becomes faster and more precise in its response to the driver's commands, while the structure is stabilized against the driving pressure affecting the model. This shoulder pattern also helps upgrade the cornering capability. The constant road contact improves the number of biting edges gripping the road surface throughout the tire's performance, which boosts the cornering and maneuvering capability. This ensures a safer controllability and maneuvering ability in various weather.
