<P>PROBLEM TO BE SOLVED: To provide a pneumatic tire improving the drive performance, the braking performance, and the turning performance in a snow icy road more than the level so far. <P>SOLUTION: A tread part includes a plurality of land parts 3 partitioned by circumferential grooves 1 extending in a tire circumferential direction and lateral grooves 2 extending in a tire width direction. At least one land 3 part comprises an annular sipe 4. A surface of a portion of the land part 5 surrounded by the annular sipe 4 includes at least one inner side slope 7 that slopes toward the annular sipe 4. A surface of a portion of the land part 6 along a periphery of the annular sipe 4 includes at least one outer side slope 8 that slopes toward the annular sipe 4. The inner side slope 7 and the outer side slope 8 are disposed so as not to be opposite each other. A step 9 is formed between first ends 7e and 8e of the annular sipe of the inner side slope 7 or the outer side slope 8 and second ends 6e and 5e of the annular sipe opposing the first ends. <P>COPYRIGHT: (C)2013,JPO&INPIT |
