Abstract
A method of retreading a tire. The method includes the steps of applying a primer to an inner surface of a circumferential tread and applying the primer to an outer surface of a tire casing; applying an adhesive to the primer disposed on the inner surface and the primer disposed on the outer surface; applying the circumferential tread to the tire casing so the inner surface contacts the outer surface and a bondline edge forms circumferentially about the tire casing proximate to a shoulder area of the tire casing; and coupling a moisture reservoir to the circumferential tread proximate to the bondline edge.
