Abstract of the Disclosure RUN FLAT DEVICE An annular ring-shaped run flat device (1) is used in tires (16) to permit continued use of the tire even when the tire is operating at low inflation pressures or is completely deflated. This device is comprised of a rigid section (4) and a non-rigid section (5). The tire, when it collapses, due to a reduction in pressure, comes to rest on the surface of the non-rigid, resilient, impact resistant section. This device is easy to assemble, can be used with conventional multi-piece rims, is light weight, durable and capable of absorbing impact under both inflated and deflated conditions. The device can also be used as a positive or non-positive bead spacer to prevent dismounting of the tire beads when tire inflation pressure drops.
