PNEUMATIC TIRE

摘要

The present invention relates to a tire with an improved kerf. According to the present invention, the tire has a three-dimensional kerf in which two kinds of cone shapes having directivity on the same position are repeatedly formed in the width direction and the depth direction of the kerf. Therefore, the tire maintains a uniform contact pressure and rigidity regardless of the moving direction of the tire, thereby improving driving performance on a snowy road and an icy road.
