PROBLEM TO BE SOLVED: To reduce rolling resistance while suppressing a deterioration in wet performance.SOLUTION: A pneumatic tire includes a block row in which blocks divided by three to five circumferential main grooves and lateral grooves are arranged at intervals in a circumferential direction. The block assumes a polygonal shape that is a five-or-more-cornered shape and all the apical angles of which are 90° or more. In the block, a maximum width position is set between axial edges at both circumferential ends facing the lateral grooves, and the ratio W1/L1 of the maximum width W1 to the circumferential length L1 of the block is in the range of 0.6-0.9. |
