Abstract
A pneumatic tire includes at least one sound absorbing member having a band-like shape. The sound absorbing member is bonded to an inner surface of a tread portion along a tire circumferential direction. A correction body for correcting weight unbalance is fixed to a tire inner surface in a range corresponding to a light point of an entire tire including the sound absorbing member.
Claims15
A pneumatic tire, comprising:
- at least one sound absorbing member having a band-like shape, the sound absorbing member being bonded to a tire inner surface of a tread portion along a tire circumferential direction;
- and
- a correction body for correcting weight unbalance being fixed to the tire inner surface of the tread portion in a range corresponding to a light point of an entire tire comprising the sound absorbing member;
- wherein
- the light point is a position where a weight of the pneumatic tire is lightest on a circumference of an entirety of the pneumatic tire including the at least one sound absorbing member,
- a range corresponding to the light point in the entirety of the pneumatic tire is a region within ±60° with respect to the light point around the center axis of a main body of the pneumatic tire, and
- a separation distance in a tire width direction between the correction body and a closest sound absorbing member of any sound absorbing member bonded to the pneumatic tire, including the at least one sound absorbing member, is not less than 5 mm.
