<P>PROBLEM TO BE SOLVED: To inhibit occurrence of uneven wear in a tire in which blocks arranged in a tread section are partitioned in the tire circumferential direction by a plurality of closed sipes extending in the tire width direction and small blocks with minimum length in the tire circumferential direction are sandwiched by small blocks other than them. <P>SOLUTION: The plurality of blocks 41 partitioned by main grooves 1, 3 and lug grooves 5 are arranged in the tread section. The block 41 is partitioned into three or more small blocks in the tire circumferential direction by the plurality of closed sipes 42a-42d extending in the tire width direction. The small block with the minimum length in the tire circumferential direction is sandwiched by the small blocks other than that. The distance between the closed sipes 42b, 42c partitioning the small block with the minimum length in the tire circumferential direction is wider in the end in the width direction than that in the center. <P>COPYRIGHT: (C)2011,JPO&INPIT |
