<p>A pneumatic tire comprises circumferential main grooves (1,2), a circumferential fine groove (3) formed between the circumferential main grooves, lateral grooves (4,5) dividing the land portions defined by these circumferential grooves (1,2) into a plurality of blocks (7,8) and at least one sipe (11,12) formed in each of the blocks (7,8), in which two corner portions (7a,8a) of each of the blocks (7,8) adjacent to the circumferential fine groove (3) are chamfered (15,16) in at least one of block rows located on both sides of the circumferential fine groove (3) so as to gradually decrease the height of the block toward the tip of each of the corner portions (7a,8a). <IMAGE></p> |
