PROBLEM TO BE SOLVED: To provide a pneumatic tire that reduces circumferential eccentric wear of the tire even if lengths in the tire circumferential direction of blocks are different from each other. SOLUTION: Each non-penetrating part 1d between blocks 1c, in which circumferential lengths in the tire of the blocks 1c circumferentially adjacent to each other in the tire are small, is formed so as to have a larger width in the tire width direction than that of each non-penetrating part 1d between blocks 1c in which circumferential lengths of the tire of the blocks 1c circumferentially adjacent to each other in the tire are large. Even if circumferential lengths in the tire of the blocks 1c are different from each other, therefore, a rigidity of each block 1c is made almost uniform over the tire circumferentially. Thus, eccentric wear is reduced. COPYRIGHT: (C)2009,JPO&INPIT |
