Abstract: A run-flat device, which is inserted into pneumatic tires to allow mobility in the event of pressure loss in the pneumatic tire, can comprise an inner ring, outer ring, and an interconnected web connecting the two. The run-flat device can support an applied load by working in tension and compression.
