PROBLEM TO BE SOLVED: To provide a pneumatic tire that can secure sufficiently dry performance and enhance on-snow performance.SOLUTION: In a pneumatic tire, in which at least five rows of land parts are partitioned by four main grooves that are provided at a tread part 1 and extended in a tire circumferential direction, the main grooves include a pair of first main grooves 11A closest to a tire equator CL and a pair of second main grooves 11B provided outermost in a tire width direction. On a center land part 20, a pair of intermediate land parts 30 and a pair of shoulder land parts 40 partitioned at the tread part are respectively provided a plurality of lateral grooves extending in a tire width direction and a plurality of sipes, which extend in a tire width direction. Sipes 23 and 43 provided on the center land part and the shoulder land parts comprise first wall-face structures whose wall faces are extended in a sipe depth direction while having amplitude in a sipe thickness direction. The sipes 33 of the intermediate land parts comprise second wall-face structures whose wall faces are extended linearly along a sipe depth direction, and sipe density of the intermediate land parts is larger than sipe density of the center land part and shoulder land parts.SELECTED DRAWING: Figure 2 |
