PROBLEM TO BE SOLVED: To provide a tire capable of restraining stone trapping such as a pebble, while reducing tire noise, when a resonator including a longitudinal groove and a peripheral groove is arranged. SOLUTION: This pneumatic tire 10 is provided with a plurality of rib-like land parts 110 and 120 partitioned by peripheral directional grooves 11, 12 and 13, a resonator R1 and a resonator R2 forming a predetermined space by recessing inward in the tire radial direction and grounding the rib-like land parts 110 and 120 on a road surface. The resonator R1 and the resonator R2 include a peripheral groove 152 and a peripheral groove 156 communicating with a longitudinal groove 154, a longitudinal groove 158 and a peripheral directional groove 12. A groove width of the longitudinal groove 154 sand the longitudinal groove 158 changes along the tire peripheral direction TC, and expands toward the road surface side along the tire radial direction. The groove depth of the longitudinal groove 154 and the longitudinal groove 158 changes along the tire peripheral direction TC, In the deepest part deepest in the groove depth, the groove width is widest, and in the shallowest part shallowest in the groove depth, the groove depth is narrowest.
