A method of treating a rubber expandable tire cure bladder by forming a base release coat thereon followed by application of a lubricant topcoat. The base release coat is derived by applying a composite of an hydroxyl terminated polyorganosiloxane and an aminoorganosilane to an expanded bladder and thereafter applying a lubricant topcoat derived from selected polyorganosiloxane components. The invention is further directed to a bladder prepared thereby and to a method of curing tires therewith.
