摘要： 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.

摘要： A tire 1 includes a circumferential direction main groove 100 extending in a circumferential direction on a tread surface, first and second circumferential direction supplemental grooves 210, 220 extending in the circumferential direction and located on both sides of the circumferential direction main groove 100 in a tread width direction, and first and second central land portions 310, 320 having a rib shape and formed between the circumferential direction main groove 100 and the first and second circumferential direction supplemental grooves 210, 220. The first and second central land portions 310,320 have plural width direction sipes 311, 321, respectively, and each of the width direction sipes 311, 321 extends to the circumferential direction main groove 100 to form an opened portion 312, 322, the circumferential direction main groove 100 has shallow grooved portions 110 and deep grooved portions 120 a depth of which from the tread surface is larger than the shallow grooved portions 110 , and a depth D1 of the shallow grooved portions 110 from the tread surface is smaller than a depth of the circumferential direction supplemental grooves from the tread surface.

摘要： This tire has a buttress section to which a plurality of depressions (100) have been formed along the tire peripheral direction (Dc). The depressions (100) have: a first outer edge (110) that bulges inward in the tread width direction (D T ); and a second outer edge (120) that is continuous with the first outer edge (110) and that bulges outward in the tread width direction (D T ) with respect to the first outer edge (110). The distance between the deepest section (150) of the depressions (100) and the ground-contact end of the tread varies along the tire peripheral direction (Dc).
