Patent ID: 6908587

Claim:
Method of post cure correction of tire uniformity for a tire having beads, an axis of rotation, and a tread having an equatorial plane; the method comprising the steps of: selecting the tire during a tire manufacturing process after the selected tire has been rejected by a tire uniformity test due to at least one tire uniformity defect; providing a 360 degree circumferential tread restraint which holds the tread of the tire in an ideal tread shape, concentric to the axis of rotation and nominally perpendicular to the equatorial plane, wherein the ideal tread shape closely matches the ideal contour of the tread of the tire when inflated; sealingly holding the beads concentric to, and equidistant from, the axis of rotation, and symmetrically spaced about the equatorial plane; and inflating the selected tire to a controlled pressure, and holding the controlled pressure for a controlled time while the tread is restrained and a beads are sealingly held.
