Abstract
Tire casings are retreaded with precured tread strips in a heated pressure vessel provided with pressure connections which effect simultaneous inflation of the tires and pressurization of the vessel while maintaining tire pressure above vessel pressure. Subsequently a pressure relief system permits the tires to exhaust faster than the vessel. Each tire is prepared for retreading by applying a bonding medium between the tire periphery and the retread strip and wrapping the resulting assembly with a fluid impervious flexible cover. Tread stabilization rings, wick material and non-stick polymer film may be inserted between the tread strip and the cover.
