摘要： The invention relates to a tire mold which includes: first and second shells (16, 18) for molding sidewalls of the tire; and a plurality of segments (20) distributed in the circumferential direction and intended to mold the tread of said tire. The segments (20) are radially movable between an open position and a closed position of the mold. The mold also includes at least one spacing means (30) inserted between each segment (20) and each shell (16, 18) such as to keep said segment and the shells spaced apart, in the radial direction, in the closed position of the mold, so that the shells and the segments are in contact with one another in the radial direction only via the spacing means. Said spacing means are capable of limiting the heat transfer between the shells and the segments in said closed position.
