Abstract
A tire noise reduction device includes a noise absorbing member formed of a porous material, a band member formed of a thermoplastic resin, the band member being an annular shape for mounting the noise absorbing member on a tire inner surface, a bonding member bent into a V-shaped cross section, and a band bonding section at a key point where the noise absorbing member, the band member, and the bonding member are bonded by interposing the noise absorbing member between the bonding member and the band member. The band member has a band width WB satisfying the following formula (a). A band thickness H (mm) of the band bonding section and a thickness h (mm) of the band member have a relationship satisfying the following formula (b). 20 mm≤WB≤noise absorbing member width (mm) (a)0.4≤H/h≤0.9 (b)
