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.

Abstract: An exemplary embodiment relates to a non-pneumatic tire for a center pivot irrigation system comprising two arcuate half-tire segments, the segments having two sidewalls connected by an outer circumferential wall and an inner circumferential wall; a plurality of transverse traction cleats circumferentially spaced on the outer circumferential wall extending between the side walls, the cleats having a rounded tip; a pair of connecting cleats at the ends of the half-tire segments having a plurality of apertures adapted for use in connecting the two arcuate half-tire segments; and a plurality of connectors adapted for insertion into the apertures wherein the cleats are tapered in width having a ratio of the center width of the cleat to the edge width of the cleat of at least about 1.25:1.
