PROBLEM TO BE SOLVED: To provide a pneumatic tire capable of reducing an air-column resonance sound generated in a major groove.SOLUTION: A pneumatic tire includes at least a major groove 3 that is continuously extended in a circumferential direction of the tire, and a land part 4. The land part 4 is provided with a longitudinal thin groove 12 that is continuously extended in the circumferential direction of the tire and that is smaller in groove width than the major groove 3. In the longitudinal thin groove 12, a first part 13 with a first groove depth d1, and a second part 14 with a second groove depth d2 smaller than the first groove depth d1 are alternately included in the circumferential direction of the tire.SELECTED DRAWING: Figure 3 |
