Abstract

The present invention covers the method and apparatus to retread tire casings using a precured tread system where an envelope or flexible fluid tight member is used to cover a retread tire casing assembly and then placed in an autoclave where the autoclave is pressurized and a reduced differential pressure is provided between the envelope member and the precured tread. This invention includes the automatic pressurizing of the system and the monitoring of the system during operation as a total system and/or for individual curing stations.
