PROBLEM TO BE SOLVED: To provide a pneumatic tire which improves dry performance by equalizing the ground contact pressure of a land section while ensuring the rigidity of the land section. SOLUTION: In the pneumatic tire, a plurality of blocks 10, which are divided by a circumferential groove extended in the tire circumferential direction, and a lateral groove extended across the circumferential groove, are formed on a tread surface. Each block 10 has corner sections 11 and 13 sharpened at least in one direction of the tire circumferential direction PD. A plurality of small holes 6 formed inwardly from wall surfaces 10a, 10b, 10c, and 10d are arranged at the corner sections 11 and 13. COPYRIGHT: (C)2011,JPO&INPIT |
