A pneumatic tire () provided with: a rib-like land portion (), a rib-like land portion (), and a rib-like land portion () which are divided by circumferential grooves () extending in the circumferential direction of the tire; and resonators which are recessed inward in the radial direction of the tire, which each form a predetermined space when the rib-like land portion () makes contact with the road surface, and which communicate with circumferential grooves. The resonators include first resonators which are provided in the circumferential direction of the tire, and also include second resonators which are, when the tire is mounted on a vehicle, located further toward the inboard side than the first resonators and are arranged in the circumferential direction of the tire.
