PROBLEM TO BE SOLVED: To provide a pneumatic tire which is improved in silence while securing the rigidity of a land part.SOLUTION: This pneumatic tire has: a first sub-groove part which has a plurality of circumferential main grooves extending to a tread circumferential direction on a tread stepping surface, and terminates in a land part at both ends in at least one land part which is defined by the adjacent two circumferential main grooves; a plurality of first resonator parts each of which is composed of the first sub-groove part and a first branch groove part opened in one circumferential main groove out of the two circumferential main grooves; a second sub-groove part which terminates in the land part at both ends; and a plurality of second resonator parts each of which is composed of the second sub-groove part and a second branch groove part opened in the other circumferential main groove out of the two circumferential main grooves. The land part has a first fine groove which is opened in the other circumferential main groove, and terminates in the land part, and a second fine groove which is opened in one circumferential main groove, and terminates in the land part. |
