To provide a tire/wheel assembly which can exhibit good run flat travelling performance.SOLUTION: An elastically deformable annular hollow body (4) is arranged in a space formed of a pneumatic tire (1) and a wheel rim (2). The annular hollow body is composed of an elastically deformable open-cell sponge rubber. The annular hollow body is expanded and contracted according to a pneumatic pressure of a tire space (5), and an outer diameter of the annular hollow body is displaced according to the pneumatic pressure of the tire space. The annular hollow body is expanded during reduction in the inner pressure by puncture, and accordingly the load is supported by the pneumatic tire and the annular hollow body. As a result, the good run flat travelling performance is obtained, and a burden on a tread part is reduced.SELECTED DRAWING: Figure 1

    【課題】良好なランフラット走行性能を発揮できるタイヤ/ホイール組立体を実現する。【解決手段】空気入りタイヤ(1)とホイールリム(2)により形成される空間内に弾性変形可能な環状中空体(4)を配置する。環状中空体は弾性変形可能な単泡性スポンジゴムで構成する。環状中空体はタイヤ空間(5)の空気圧に応じて膨張及び収縮し、環状中空体の外径はタイヤ空間の空気圧に応じて変位する。パンクによる内圧低下時には環状中空体は膨張するので、荷重は空気入りタイヤと環状中空体によって支持される。この結果、良好なランフラット走行性能が得られると共にトレッド部の負担が軽減される。【選択図】図1
