This directional tread pattern keeps close road contact, which upgrades steering responsiveness and driving stability. As a result, the steering response becomes faster and more precise to the driver's commands, while the structure is secured against driving pressure. At the same time, the optimal grooves and tread pattern boosts cornering and maneuvering. This tread design also shortens the braking distance, by creating friction at the moment of the braking. This significantly enhances the driver's control over the vehicle.
