PROBLEM TO BE SOLVED: To increase abrasion resistance in response to a difference, generated by a difference in the placing position of a tire, in the input direction of external forces. SOLUTION: An outside block 18 formed in a parallelogram shape is disposed outside a front tire 10A. An inside block 20 formed in the parallelogram shape is disposed inside the front tire 10A. A sipe 26 is installed on a one-by-one basis in the blocks 18 and 20, respectively, and the central main part 26A of the sipe 26 installed in the blocks 18 and 20 is formed in such a manner as to extend along the diagonals of the blocks 18 and 20 slantingly relative to an equatorial plane. |
