发明名称 METHOD OF CONTROLLING TREAD SHRINKAGE DURING CURING
摘要 In particular embodiments, a method of forming a retreaded tire includes the steps of: applying a tread to a tread-engaging portion of a tire carcass, the tread having an initial width and a layer of cushion gum interposed between the tread and tire carcass; placing a curing membrane about the tread to form a tire curing assembly having a compartment between the membrane and tread; placing the tire curing assembly in a vessel chamber; pressurizing the chamber to a predetermined pressure; heating the chamber to a predetermined temperature; pressurizing the compartment to a pressure greater than 14.7 psia and less than the chamber pressure to provide a pressure differential, the step initializing after the step of pressurizing the chamber initializes and whereby a final tread width is provided that is equal to 98.0% or more of the initial tread width when the initial tread width is approximately 290-500 mm.
