ABSTRACT:
Disclosed is a tire/wheel assembly in which a run-flat support member is disposed in a cavity of a pneumatic tire fitted to a rim. The run-flat support member includes a circular shell, in which an outer circumferential side thereof is a support surface and an inner circumferential side thereof is opened to have two leg portions, and left and right elastic rings which support the two leg portions on the rim. The elastic rings have different rigidities from each other so that the elastic ring receiving a larger load during run-flat traveling has a higher rigidity.
