Abstract
In order to maintain a pneumatic tire in an operational state after the tire has been deflated, a combined structure is embedded within the crown portion of the tire to resist compressive forces encountered when the tire is deflated. The combined structure includes a prestressed coil located adjacent coaxially spaced band segments. Radial plies are present in the tire to transmit compressive forces from a ground contact area to the combined structure which resists the compressive forces successfully.
