<P>PROBLEM TO BE SOLVED: To suppress damage to a block, while suppressing uneven wear of the block, in the block formed with an open sipe. <P>SOLUTION: In the center block 24B, the first sipe 30 is formed. The first sipe 30 is made to have a crest type having amplitude in a tire peripheral direction. When a tire peripheral direction length of the center block 24B is L and a maximum value of the tire peripheral direction amplitude of the first sipe 30 is A1, both of L and A1 satisfy a relation of A1/L≥0.3. Namely, the maximum amplitude A1 of the first sipe 30 is made to have ≥30% of the tire peripheral direction length L of the center block 24B. <P>COPYRIGHT: (C)2012,JPO&INPIT |
