PROBLEM TO BE SOLVED: To provide a tire capable of compatibly achieving driving performance and drainage property, when a lug groove is formed. SOLUTION: This pneumatic tire 1 includes at least a land part 10 formed by the lug groove 100A extending toward the tread width direction TW outside. The land part 10 includes a first land part including a groove wall 10a to form the lug groove 100A, and a second land part including a groove wall 10b to form the lug groove 100A. The groove walls 10a and 10b meander along the tread width direction TW in a tread surface view. A groove width of the lug groove 100A is changed at a prescribed repeated period along an extended direction S of the lug groove 100A. The lug groove 100A includes a wide groove part 110 where the groove width orthogonal to the extended direction S of the lug groove 100A is a prescribed width, and a narrow groove part 120 continuous to the wide groove part 110 and narrower than the prescribed width.
