Abstract

A method of embossing a tread pattern on a tire tread, comprising a vulcanizing phase of the tire in a mold during which pressures generated by a vulcanizing fluid are exerted within the tire in the mold, such mold being provided with two parts predisposed to compress the sidewalls of the tire and a plurality of sectors predisposed to compress the perimeter strip of the tire itself, characterized by the fact that, when inside the tire, the pressure of said fluid acts For vulcanization, forces generated by means of elastic forcing deformations of one or more parts of the mold are applied to said sectors of the mold, such forces opposing the radial movements of said sectors generated by said pressures inside the tire.
