ABSTRACT:
The present invention provides a tire/wheel assembly and a run-flat support member. A pneumatic tire is fitted to a wheel rim; and the run-flat support member constituted of a circular shell and elastic rings is inserted into a cavity of the pneumatic tire, in which the circular shell has a support surface thereof extended toward the periphery of the tire and leg portions along each side of the support surface, and the elastic rings support the leg portions of the circular shell on the rim. In the tire/wheel assembly, the leg portion of the circular shell is formed to have a sidewall extending in a shell radial direction and a bottom wall that is substantially parallel to a shell axial direction. The elastic ring is attached to the sidewall of the leg portion while being abutted on the bottom wall of the same without an engagement.
