Abstract:
A pneumatic tire (10) provided with a rib-like land portion (110) having first resonators formed therein, and also with a rib-like land portion (210) located, when the tire is mounted on a vehicle, on the side of the tire closer to the vehicle than the rib-like land portion (110) and having second resonators formed therein. Each of the first and second resonators includes an air chamber recessed inward in the radial direction of the tire, and also includes a narrow groove communicating with the air chamber and a circumferential groove. The volume of the air chamber of the first resonator is greater than the volume of the air chamber of the second resonator.
