PROBLEM TO BE SOLVED: To provide a tire having high durability by suppressing the heal-and-toe wear of a land part provided with a communication groove part constituting a resonator.SOLUTION: In a tread surface 2, there are provided circumferential direction grooves 3, 4 and 5 extending over the whole circumference of the tire and rib-shaped land parts 8 and 9 partitioned by the circumferential direction grooves 3, 4 and 5 and shoulder land parts 10 and 11. In the rib-shaped land parts 8 and 9, a plurality of resonators 12 including a concave air chamber part 13 opened in the surface of the rib-shaped land parts 8 and 9 and a communication groove part 14 communicating the air chamber part 13 with the circumferential grooves are provided, and the communication groove part 14 constituting the resonator 12 is inclined in the tire circumferential direction to the tire radial direction so that the opening of the communication groove part 14 is located in the rear of the bottom part in the tire rotation direction. |
