Disclosed is a vehicle wheel structure in which a tubeless pnumatic tire (3,13,23) is fitted over a wheel (1,11,21,31) and at least two walls (9,19,29,34) project in substantially radial directions from an outer circumferential surface of the wheel into the annular chamber defined between the tire and the wheel. These walls prevent the generation of standing waves or air column resonance inside the tire and thus contribute to the overall reduction of the road noise of the vehicle. The inner ends of the walls (9,19,29,34) may be either bonded to an annular member which surrounds the wheel or pivoted to a similar annular member and biased into their radial or upright positions by a spring member (37), in such a manner as not to interfere with the replacement of the tire. Alternatively, the walls (29) may consist of inflatable bags which may be inflated into radial positions and deflated into flat positions. |
