Abstract
Embodiments of the invention include methods for supporting a recessed void during retreading operations. Such methods include the steps of providing a tread having a top side and a bottom side, the tread including a recessed void recessed below the top side of the tread. Such methods also include the step of arranging the tread around an outer circumference of the tire carcass in a desired position to form an assembled retreaded tire. Such methods further include the step of arranging a removable circumferential band around the assembled retreaded tire positioned over top the recessed void and the top side of the tread. Such methods further include the steps of placing a curing membrane around at least a portion of the tire and the circumferential band and curing the retreaded tire with the circumferential band contained within the curing membrane.
