A mold for a tire is disclosed herein. The mold includes first and second shells mold-able to lateral sidewalls of the tire, and a plurality of sectors that are distributed in the circumferential direction and are mold-able to the tread of said tire. The sectors are radially movable between an open position and a closed position of the mold. The mold also comprises at least one spacing interposed between each sector and each shell in order to keep said sector and the shells spaced apart in the radial direction in the closed position of the mold, such that the shells and the sectors are in contact in the radial direction only by way of the spacing. The spacing is also able to limit the heat transfer between the shells and the sectors in said closed position.
