Abstract
Exemplary embodiments of the subject invention comprise methods and apparatus for mounting a tread ring onto a tire carcass. Such methods may include the step of providing a tire tread ring having opposing side edges; arranging the tread ring in an initial ring arrangement in communication with a pressure source, the pressure source being in communication with an outer side of the tread ring; expanding the tread ring radially outward from the initial ring arrangement to an expanded arrangement, the tread ring being expanded by applying vacuum pressure along the outer side of the tread ring supplied by the pressure source; inserting a tire carcass within a central opening of the tread ring while in the expanded arrangement; contracting the tread ring into an installed arrangement about an outer surface of the tire carcass; and, releasing the vacuum along the outer side of the tread ring.
