Abstract
A tire is manufactured by assembling a tread package into a pattern ring and molding a tread thereon while partially precuring the package. The tire is further assembled by positioning an uncured carcass within the pattern ring so that the carcass contacts an uncured portion of the tread package. Finally, the assembled tire is separated from the pattern ring and subsequently heated in a mold devoid of a tread pattern to bond and cure the complete tire.
