Straight Sides Patents (Class D12/584)
  • Patent number: 9868325
    Abstract: 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 are arranged in at least one circumferential groove at intervals in the tread circumferential direction, the protuberances being raised from the inner surface of the circumferential groove and extending from the groove bottom of the circumferential groove to at least one groove wall surface in the tread width direction. A plurality of sipes are arranged in a land portion adjacent to the groove wall surface of the circumferential groove to which the protuberances extend, the sipes being open to the circumferential groove in areas where the respective protuberances are arranged.
