Abstract
A tire including a land part partitioned between two main grooves extending in the tire circumferential direction S of the tire and resonators formed in the land part. A resonator has a cavity part separated from the two main grooves and is opened at the surface of the land part, a 1st sipe that is opened at one main groove and the cavity part, and a 2nd sipe that is opened at the other main groove and the cavity part. Depths of the main grooves are 3 mm or more and 6.5 mm or less. A volume value of the cavity part is more than 3 times or more and 5 times or less a sum of the cross-sectional areas of the two main grooves with the land part in between, and lengths of the 1st sipe and the 2nd sipe are 10 mm or more and 25 mm or less.
