Abstract
A pneumatic tire including a noise reduction device in a cavity portion thereof. The noise reduction device has a noise absorbing member formed of a porous material; a band member for attaching the noise absorbing member to the inner surface of a tire; and locking members formed of a thermoplastic resin. Preferably, the band member is formed of a thermoplastic resin, and the noise absorbing member is disposed between the band member and the locking members. Also, the locking members are bonded to the band member through the noise absorbing member by thermal fusion, and the constituent material of the band member and the constituent material of the locking members are the same thermoplastic resin.
