<P>PROBLEM TO BE SOLVED: To provide a pneumatic tire capable of suppressing uneven wear between a plurality of block land parts, while maintaining steering stability. <P>SOLUTION: The pneumatic tire are sectioned with first and second rib form land parts 21 and 22 in the intervals of three circumference direction main grooves 11, 12 and 13 arranged in a tread section 2. First and second circumference direction sub-grooves 31 and 32, each of the number of which is one, and first to fourth width direction grooves 41, 42, 43 and 44 are arranged in the first and second rib form land parts 21 and 22. Thereby section-forming first to fourth block land parts 23, 24, 25 and 26. Here, the plurality of first to fourth block land parts 23, 24, 25 and 26 are equal in a circumference direction block length and a block height, and the first block land part 23 and the second block land part 24 are arranged with a predetermined phase difference, and the third block land part 25 and the fourth block land part 26 are arranged with a predetermined phase difference. <P>COPYRIGHT: (C)2012,JPO&INPIT |
