Claim:
1. A tire vulcanizing mold adapted to cooperate with a curing press, said mold comprising: two shells, each one molding a sidewall of the tire, and a ring of sectors for molding the tread of the tire, wherein each sector comprises: wherein the sectors of the ring, when the mold is in the closed position, are all in circumferential contact one with the next via the molding linings and in radial contact on the shells via front ends of the molding linings, each of which forms a face for contact with the shell, wherein said supports and linings are produced in such a way that each support is able to take up a clamping force applied to the lining coming into contact with the shell when the mold is in the closed position when said clamping force at said contact face exceeds a given threshold that is lower than the plastic threshold of the lining, wherein a predetermined clearance (j) is provided between a lower front face of the shell and a lower front end of the support, and wherein this clearance (j) is cancelled out when the mold is in the closed position.
