A pneumatic tire, while achieving excellent drainage performance by projections and depressions formed in a circumferential groove, can reduce road noise by making the circumferential stiffness of a land portion uniform even in the presence of such projections and depressions. A plurality of protuberances 6 are arranged in at least one circumferential groove 3 at intervals in the tread circumferential direction, the protuberances 6 being raised from the inner surface of the circumferential groove 3 and extending from the groove bottom 3a of the circumferential groove 3 to at least one groove wall surface 3b in the tread width direction. A plurality of sipes 7 are arranged in a land portion 4 adjacent to the groove wall surface 3b of the circumferential groove 3 to which the protuberances 6 extend, the sipes 7 being open to the circumferential groove 3 in areas where the respective protuberances 6 are arranged. |
