The stable center rib upgrades the steering responsiveness and driving stability by maintaining the road contact at all times. The steering's response time and accuracy and the structure's stability are boosted in this manner. The shoulder tread pattern's road contact and the slanted grooves of the middle ribs stabilize the tread elements and prevent tread flexing. As a result, the tire has a firmer grip on the road surface during cornering and maneuvering, guaranteeing a secure performance. The better steering response, driving stability and cornering capability enable the driver to confidently control the vehicle in all conditions.
