A tire curing mold comprising two shells that are each intended to mold a sidewall of a tire and a ring of sectors that are intended to mold a tread of the tire, each sector having a lining and two segments that are arc shaped,
- wherein each segment is arranged so as to fill a clearance at an interface between the lining and one of the two shells, and is arranged so that spacing between each segment and a molding surface of the tire curing mold is 0.1 mm to 10 mm so as to not be coincident with the molding surface of the tire curing mold, including not being coincident with the molding surface of the tire curing mold during vulcanization of the tire such that the tire curing mold is capable of forming markings on a shoulder of the tire.
