Abstract

A pneumatic tire and wheel rim assembly containing a support hoop which supports the vehicle to which the assembly is fitted when the tire deflates by contacting the inside of the tire tread at the top and bottom of the assembly. The dimensions of the hoop are such that its inner surface does not touch the rim whether the tire is inflated or deflated, and its outer surface does not touch the tire when inflated normally.
