ABSTRACT OF THE DISCLOSURE : A method of retreading rubber tyres, said method comprising applying to a tyre carcass a prevulcanized tread with a vulcanizable bonding layer interposed therebetween, enclosing said tread and at least the adjacent part of said carcass with a flexible envelope and subjecting the resulting blank comprising said carcass, tread, and bonding layer, to a pressure- and heat- treatment in an autoclave and pressing the flexible envelope in to close fit with the tread at least at the outside parts of the road engaging surface to bond said tread to said carcass, pressurizing the bottom of the interstices between the projecting portions formed in the tread profile to avoid distortions of the profiled tread during said pressure- and heat-treatment by a pressure medium of the gaseous inclusions between the envelope and said blank or the fluid of the autoclave by effecting a flow of the pressure medium between a reservoir adjacent to the tyre blank and a space formed by said close fitting envelope and the bottom of said interstices of the tread by the action of the pressure in the autoclave in the absence of conduits connecting said space or said reservoir to the outside of the autoclave.
