PROBLEM TO BE SOLVED: To provide a pneumatic tire capable of making both compatible in dry performance and wet performance of the tire.SOLUTION: In a pneumatic tire 1, a circumferential directional thin groove 24 is arranged in a position partitioning an outside second land part 34 and an outside shoulder land part 35. A center land part 33 is a rib of continuing in the tire circumferential direction, and an inside second land part 32 and the outside second land part 34 are block rows divided in the tire circumferential direction by a plurality of lug grooves 321 and 341. The groove area ratio S2 of the center land part 33, the groove area ratio S1 of the inside second land part 32 and the groove area ratio S3 of the outside second land part 34, have the relationship of S2<S3<S1. A groove width Wd of the circumferential directional thin groove 24 and a maximum valve Wmax of groove widths of the other three circumferential directional main grooves 21-23, have the relationship of 3.1≤Wmax/Wd≤5.0. |
