Abstract
A method for retreading vehicle tires. A carcass is provided with a prevulcanized tread and an unvulcanized tie-gum layer between the carcass and tread. A microwave applicator is located above the tread for emitting microwaves to the tire for creating heat energy in the tire. A reflector for microwaves comprising an electrically conductive material is attached in connection to or in the tie-gum layer to achieve high quality rapid vulcanization without heating the carcass.
