Abstract

Method of renewing the running surface of a worn tire or heavy tire, according to which a layer of binder rubber is applied to the previously prepared carcass of the tire and on those a prefabricated rubber tread which, for large tires with strong tacos, preferably consists of portions or segments of tread band joined together, the gaseous inclusions being avoided or expelled between the applied layers, and the raw tire thus prepared is heated in an autoclave to vulcanize the layer of binder rubber, characterized by the the fact that a tread or ring of tread presents on its underside a rough face of projections and cavities forming a network of ducts, which is produced in the press mold at the same time as the drawing of the band and remains suitable for joining, is placed on the casing greased rubber binder layer and all inclusive n gaseous is directed out of the layers by the application of reduced pressure, whereby the lateral outlet openings of the superposed layers are closed, and/or by squeezing by exerting mechanical pressure on the tread.
