ABSTRACT:
Disclosed is a vehicle tire structure in which a tubeless pneumatic tire is fitted over a wheel, characterized in that: at least a pair of walls project in substantially radial direction from an outer circumferential surface of the wheel into an annular chamber defined between the tire and the wheel. These walls prevents the generation of standing waves or the air column resonace inside the tire and contribute to the overall reduction of the road noise of the vehicle. The proximal ends of the walls may be either bonded to an annular member which surrounds the wheel or pivoted to a similar annular member and biased into radial or upright positions by a spring member, in such a manner as not to interfere with the replacement of the tire. Alternatively, the walls may consist of inflatable bags which may be inflated into upright positions and deflated into flat positions.
