Abstract: A combination tire and mounting plate are described. The tire portion of the combination is a molded, one-piece, non-pneumatic tire, preferably made by rotational molding. The mounting plate portion of the combination has a central aperture therein and is configured to be coupled to a conventional hub. The combination further includes a fastener dimensioned to attach the mounting plate to the tire so that the central aperture of the mounting plate is coaxial with the central aperture of the tire. This permits the tire/mounting plate combination to be reversibly mounted coaxially on a conventional hub.
