To provide a tire further reduced in tire noise, particularly further reduced in pass-by noise by using a resonator forming a space, through contact with a road.
This pneumatic tire 10 is provided with: a plurality of rib-like land parts 110, 210, 240; and resonators R1, R2, R3 indented inward in a tire radial direction, forming a predetermined space by contact of the rib-like land parts and a road, and communicated with a peripheral groove. The resonators include: a plurality of resonators R1 provided along the tire peripheral direction; and a plurality of resonators R2, R3 positioned inside the resonators R1 in mounting a vehicle, and provided along the tire peripheral direction. The resonator R1 is a side branch type resonator having a vertical groove and a lateral groove communicated with the peripheral groove 12, and the resonators R2, R3 are Helmholtz type resonators having: an air chamber part intended inward in the tire radial direction; and a narrow groove part communicated with the peripheral groove 21. A capacity of the resonator R1 is larger than capacities of the resonators R2, R3.
