Patent ID: 6842958

Claim:
A method of fitting a resilient ring substantially circular in shape into a tire, and removing it therefrom which comprises the following steps in sequence: first deforming of the resilient ring by slightly extending or stretching it along one diameter thereof so as to cause it to change from a circular to an elliptical shape; fitting the thus deformed resilient ring lengthwise into the light of a tire in which the ring is to be assembled; first releasing of the resilient ring whereby it tends to resiliently regain its initial circular shape while remaining engaged in the tire light; rotating the resilient ring through approximately 90 degrees about an axis coinciding with said radial direction with respect to the tire; second deforming of the resilient ring by stretching or extending it in a radial direction in the tire, wherein said second deforming Is preceded by a relative angular movement of about 90 degrees between tire and resilient ring in its circular configuration; and final releasing of the deformable ring whereby it regains its circular shape within the tire.
