Abstract
Disclosed are a tire/wheel assembly and a run-flat support member which are designed to be lightened without losing durability during run-flat traveling. The tire/wheel assembly is constituted as follows: a pneumatic tire is fit 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. The circular shell has a support surface thereof extended toward the periphery of the pneumatic tire and leg portions along each side of the support surface. The elastic rings support the leg portions of the circular shell on the rim. In the tire/wheel assembly, contact portions and noncontact portions for the circular shell are alternately formed on the elastic rings in a shell circumferential direction.
