Open the CIPO recordAbstract From the Canadian patent
A belted one-ply radial tire is disclosed which is characterized by a circumferential cord-fabric insert between the inner liner and the ply. The insert is of a material with good compressive fatigue resistance such as polyester cord. m e single ply is continuous. The benefits of the high modulus radial ply cords are thus retained and the disadvantages due to, the poor compressive fatigue resistance of such cords are reduced or compensated for by the insert so that a durable one-ply radial tire with improved low rolling resistance is obtained.
