Claims5
A pneumatic tire, comprising:
- a block that is partitioned by a plurality of circumferential direction grooves extending along a tire circumferential direction and by a plurality of lug grooves extending diagonally with respect to the tire circumferential direction and provided with two or more bend portions;
- and
- at least one inclined fine groove that extends diagonally with respect to the tire circumferential direction, that is provided with two or more bend portions inside the block, and that divides the block;
- the pneumatic tire further comprising two or more circumferential direction fine grooves extending along the tire circumferential direction inside the block so as to partition the block and having a same groove width as the inclined fine groove, wherein
- the circumferential direction fine grooves are disposed so as to intersect with bend portions of the inclined fine groove, the bend portions being next to each other along a tire axial direction within the block, and each circumferential direction fine groove being formed only between the bend portions of the lug grooves adjacent to each other in the tire circumferential direction, and wherein
- the circumferential direction fine groove is formed with a shallower groove depth than the inclined fine groove.
