To provide a pneumatic tire that has a high wet performance while having a high anti-wear performance.
A first land part row 30 and a second land part row 32 divided by a first tire circumferential direction groove 22 and a second tire circumferential direction groove 26 and center tire circumferential direction groove 24 are formed in the tire tread. The first land part row 30 and the second land part row 32 are divided into a plurality of blocks 34 and 36 respectively by tire width direction groove 28. The tire width direction groove 28 is formed to be wider than the center tire circumferential direction grooves 24, and to cross the land part row. In blocks 34 and 36, the length of the cross sectional of the tire width direction increases from both ends of the tire circumferential direction toward the tire circumferential direction center part, and the width length in the tire width direction is 15-30% against the width of the tire tread.
