PROBLEM TO BE SOLVED: To remarkably improve wear resistant performance under a traveling condition, mainly, under a straight traveling condition. SOLUTION: In this tire, land part lines 3, 4 and 5 are formed in a tread by a plurality of circumferential grooves 1 and 2, and nearly parallelogram blocks 7 are formed in the plurality of land part lines by narrow grooves 6 extended to cross the land part lines 4 and 5, and rotating direction of the tire is specified. In each block 7, a circumferential edge 8 on a tread side edge side is extended with an inclination against a tread circumferential line c, and a kick-out side edge 9 of the block is positioned on a tread central part side in relation to an operating side edge 10.
