Tire tread

A method for producing a mold lining (G) intended for the manufacture of tires comprising tread blocks that have incisions in them and studs. A mold lining is produced by positioning lamella (L, L, L, L, L, L) of substantially equivalent shape and length on the parts of the lining (G) that are intended to mold the rubber blocks. In a next step, the material of the lining (G) and of the lamella (L, L, L, L, L, L) contained in a cylindrical space located at each of the sites intended to accept pins capable of molding the housings for the studs is removed radially, and an insert supporting a pin is positioned in the hole obtained beforehand.
