ABSTRACT:
An annular ring-shaped run flat device is used in tires to permit continued use of the tire even when the tire is operating at low pressure or is completely deflated. This device is comprised of a rigid section and a non-rigid section. 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 and non-positive bead spacer to prevent dismounting of the tire beads when tire pressure drops.
