Abstract
A method and apparatus for reducing the magnitude of a uniformity characteristic in a cured tire and the tire produced thereby. A signal is generated which is indicative of the magnitude of the uniformity characteristic. The signal is also indicative of the location on the tire to be corrected. At least a portion of one carcass reinforcing member of the tire is permanently deformed a predetermined amount at the location indicated by the signal to correct the uniformity characteristic.
Claims8
A method for reducing the magnitude of a uniformity characteristic in a cured tire, said method comprising the steps of:
- determining a location on the tire to correct;
- and
- introducing a radial runout to the tire as a function of the determined location to offset the uniformity characteristic and reduce the magnitude of a resulting uniformity characteristic to below a minimum threshold magnitude.
