Abstract
Provided is a tire wheel assembly making it possible to effectively reduce cavity resonance noise without causing either negative influence on deformation of a tire or deterioration in rim assembling workability. A tire wheel assembly of the present invention includes a pneumatic tire, and a wheel provided with a rim fitted with the pneumatic tire, and forms a cavity portion between the pneumatic tire and the rim. The tire wheel assembly comprises at least one tube, which has one end thereof closed while having a length of 55% to 110% of a reference length L0 corresponding to one fourth of a cavity resonance wavelength, is provided so as to open to the cavity portion.

A tire wheel assembly which includes a pneumatic tire, and a wheel provided with a rim fitted with the pneumatic tire, and forms a cavity portion between the pneumatic tire and the rim, wherein:
- at least one tube, which has one end thereof closed while having a length of 55% to 110% of a reference length L0 corresponding to one fourth of a cavity resonance wavelength, is provided so as to open to the cavity portion.
A tire wheel assembly, which includes a pneumatic tire, and a wheel provided with a rim fitted with the pneumatic tire, and forms a cavity portion between the pneumatic tire and the rim, wherein:
- a plurality of tubes, each of which has one end thereof closed while having a length of 55% to 110% of a reference length L0 corresponding to one fourth of a cavity resonance wavelength, are provided so as to open to the cavity portion;
- and
- opening portions of these tubes are arranged in one arbitrary location on a circumference, or in two locations facing each other across a rotational axis of the tire.
