Patent ID: 7790075

Claim:
A method for reducing the magnitude of uniformity characteristics in a cured tire using a supporting ring, the tire defining axial and circumferential directions, the method comprising the steps of: providing a look up table containing the amount of restraint as a function of the magnitude of correction of a uniformity characteristic as developed from previously corrected tires; generating a signal indicative of the magnitude and location of uniformity characteristics for the cured tire; selecting from the look up table the amount of restraint to be provided by the supporting ring for correction of the uniformity characteristics of the cured tire; placing a plurality of plates about the supporting ring so as to provide the amount of restraint from said selecting step to the cured tire; and, applying the supporting ring with the plurality of plates to the cured tire so as to constrain at least one sidewall of the tire with at least one of said plates in order to cause permanent deformation and correction of a uniformity characteristic.
