A segmented mold comprising a plurality of segments is provided. The segments are arranged to form an annular cavity to mold a tire, the segments comprising an inner face for molding the tread, and an outer radial surface. The mold further includes a plurality of slide blocks located radially outwards of the segments. Each slide block may have flanged ends and an inner cavity for receiving a segment therein. One or more channels are provided between each segment outer surface and the adjacent slide block inner surface forming a fluid passageway, wherein each fluid passageway is joined together by a fluid connector to form a fluid manifold for circulating a fluid medium. Steam may be circulated in the fluid manifold during curing of the mold.
