ABSTRACT:
A circular insert is located within a tire and is adapted to contact the interior surface of the tire side walls when the tire becomes deflated. The insert is positionally interposed within the folds of a bulging side wall during deflation and transmits load between the side wall and a tire rim to prevent complete collapse of the run-flat tire.
