Abstract: A method is for producing a profile segment of a segmented casting-vulcanizing mold for vehicle tires, the molding area of which molds a segment of the tread profile of a tire to be vulcanized, including the steps: creating a rigid model segment having a casing-like tread surface; milling the profile positive of the tread into the casing-like tread surface of the model segment to obtain the master model; creating a flexible impression from the master model; creating a rigid plaster cast from the impression to form a casting core segment; casting all of the annular, placed-together casting core segments with an aluminium-magnesium alloy to obtain a vulcanizing mold, subsequently divided into profile segments. A plasma coating is applied to the tread of the model segment, into which the profile positive of the tread is subsequently milled to obtain the master model. Plasma coating gives the master model a defined roughness.

Abstract: A tire vulcanizing mold has two or more mold segments with forming surfaces jointly defining the tread rubber profile of a tire to be vulcanized and with a surface area with elevations, such as webs, wherein the surface area forms the circumferential tread rubber profile area of the tire and wherein the elevations impress the depressions, such as grooves, in the tread of the tire. A tire vulcanized with the vulcanizing mold may be a motorcycle tire or an ultra-high performance tire. Certain regions of the forming surfaces of the mold segments that form the tread rubber profile are provided with a roughness, such that those regions of the vulcanizing mold which form the circumferential tread rubber profile area are provided with the roughness. The elevations, on the other hand, which impress the depressions are not provided with this roughness but they are instead smooth.
