PROBLEM TO BE SOLVED: To provide a tire capable of further suppressing noise caused by an air column pipe resonance sound while ensuring drainage performance. SOLUTION: In the tire, a circumferential groove 18 or a lateral groove extending along a tire circumferential direction R or a tread width direction W is formed on a tread surface 16a, and a sound absorption system including a sound absorption part 70 arranged in the circumferential groove 18 or the lateral groove and absorbing the air column pipe resonance sound generated from the air column pipe formed by the circumferential groove 18 or the lateral groove and a road surface and a mounting part 50 provided in the circumferential groove 18 or the lateral groove and fitted with the sound absorption part 70 is provided. An end part at an outer side in a tire radial direction of the sound absorption part 70 is positioned at an inner side in the tire radial direction than the tread surface 16a.
