Abstract
A method for recapping a solid tire with precured tread rubber is disclosed. The method comprises preparing a used solid tire for recapping, including buffing down the tire to remove the old tread and to prepare the surface; applying intermediate bonding material including cushion gum; adding precured padding stock for a base layer where needed; applying and splicing together the precured tread rubber strip; placing wicking material across the tread rubber surface, for air bleeding; enveloping the tire; placing the enveloped tire assembly in a curing module having annular sealing means that can be pressed against the envelope at both tire sidewalls to form a sealed space around the envelope; and supplyng heat and pressure in the space to press the envelope and tread rubber against the tire carcass while curing the internal layer(s) of bonding material, thereby securing the layers together and forming an integral retreaded tire.
