PROBLEM TO BE SOLVED: To provide a difference in the lateral rigidity of the tread surface that instantly adapts to the lateral acceleration while turning at high speeds. SOLUTION: The tread surface 1 is composed of a block pattern 2 on the inside and a rib pattern 3 on the outside. The lateral rigidity of the outside is higher than that of the inside. The outside lateral rigidity is increased to be more than that of the inside by increasing or decreasing the surface area of the blocks and ribs, or increasing or decreasing the number of transverse grooves or the groove width. Furthermore, means for visual discrimination when the tire is mounted on the automobile is provided on the tread surface 1. |
