  • Vehicle tire comprising pneumatic tire inserts
    Patent number: 4324279
    Abstract: A method and article of manufacture is herein disclosed for eliminating the need for pressurized air in a vehicular pneumatic tire. A resilient tubular insert is inserted and carried within a tire casing to simulate pneumatic conditions. The resilient material possesses a longitudinal bore which in combination with a particular range of durometers, enhances the "pneumatic" characteristics of the tire insert. Preferably, the tire insert is discontinuous and is designed to have a diameter greater than the internal diameter of the tire casing under deflated conditions.
