Abstract: A curing jacket for use in conjunction with a tire to be recapped having a pair of sidewalls and a tread. The curing jacket includes a unitary tubular envelope having first and second edges. The curing jacket is sized to encase the tire by extending around a circumference of and adjacent to interior and exterior surfaces of the sidewalls and tread of the tire. An O-ring on the first edge of the tubular envelope fits within a seat on the second edge to provide an airtight seal. Air is evacuated from the envelope through a valve. The jacketed tire is cured in a curing oven.
