PROBLEM TO BE SOLVED: To enhance the running performances on snowy and icy roads while maintaining a block rigidity and securing wear resistance.SOLUTION: Blocks 4 are formed on a tread surface 1 by main grooves 2 extending in a circumferential direction and lateral grooves 3 crossing the main grooves 2. The block 4 in which the width direction of the tread surface 1 is set longer compared to a circumferential direction is provided with: center blocks 5 positioning at a central area in a tire width direction; shoulder blocks 6 positioning at both side areas in the tire width direction; and mediate blocks 7 positioning at the intermediate area between the center and shoulder blocks 5 and 6. Besides, dent parts 12 are formed on the nearly central parts between the shoulder and mediate blocks 6 and 7. |
