PROBLEM TO BE SOLVED: To provide a pneumatic tire capable of suppressing rigidity reduction of a specific land block even if a lot of sipes are formed in the specific land block.SOLUTION: A pneumatic tire 1 is formed with a first center land part line 5, a second center land part line 7, and shoulder land part lines 9 and 10 that are a plurality of land part blocks on a tread surface by a center side circumferential-direction groove 2, a mounting outer side circumferential-direction groove 3 and a mounting inner side circumferential-direction groove 4 extending in the tire circumferential direction, and lateral grooves 6 and lug grooves 8, 11 and 12 crossing the circumferential-direction grooves 2, 3 and 4 and extending in the tire width direction, and is formed with sipes 21-24 on the surfaces of the respective land part blocks. A prescribed land part block 31 of the plurality of land part blocks has a higher sipe density than the other land part blocks, is set with a smaller negative ratio than the other land part blocks, and is disposed in a position offset on the mounting outer side rather than the tire center. |
