Abstract
This is an elastomeric safety insert for a pneumatic tire assembly. The insert when installed has a toroidal configuration and has protuberances extending therefrom to space the body portion of the insert from the rim and tire casing, permitting the insert to dynamically balance itself when the tire is rotated.
