ABSTRACT:
A method and an apparatus for contouring the shoulder areas of retreaded tires is disclosed. A cutter, preferably having a heated blade, is disposed proximate at least one shoulder of a retreaded tire. The retreaded tire is then rotated, while the cutter blade is moved into contact with the side wall of the tire proximate the joint between the tire casing and the tread layer. A portion of the tire casing and the tread layer is cut away along the entire shoulder area of the retreaded tire to provide an aesthetically pleasing contoured surface extending from the tire casing to the tread layer.
