<p>A multi-piece sealing sleeve is disclosed. The multi-piece sealing sleeve includes annular first and second layers of a substantially air-impermeable material. The first layer has an inner edge sized to surround a base portion of the tire shaping drum. An outer edge of the first layer extends radially outwardly to overlie at least a portion of a radially expandable and collapsible structure defined by the tire shaping drum. The second layer is sized to overlie and establish sealing engagement with at least a portion of the first layer and a bead seat defined by the radially expandable and collapsible structure of the tire shaping drum. The first and second layers cooperate to establish a substantially airtight seal between the tire shaping drum base portion and the bead seat.</p>
