<P>PROBLEM TO BE SOLVED: To provide a pneumatic tire enhanced in on-ice performance and on-snow performance at braking. <P>SOLUTION: This pneumatic tire includes a block as a tread pattern on the tread part, and the rotating direction of the tire is specified. Sipes are formed in the block, wherein the length of the wall surface of the sipe on the tread-in side of the block is L1 and the length of the wall surface of the sipe on the kicking side of the block is L2 in the cross section of the block in the tire circumferential direction, L1 is smaller than L2. The width of the sipe is maximum at a position of 40-80% inclusive of the depth of the sipe in the depth direction of the sipe. <P>COPYRIGHT: (C)2011,JPO&INPIT |
