ABSTRACT:
An improved dual wheel construction includes a first inside rim and a second outside rim. The inside rim includes a typical hub plate construction for attachment of the rim to the axle of a vehicle such as a tractor. The outside rim includes a plurality of circumferentially spaced plates projecting laterally, outwardly from the side of the outside rim. A closed circular ring member interconnects the plates. A plurality of openings are defined in the ring. Fastening bolts and nuts connect the hub plate of the inside rim to the ring member associated with outside rim and maintain the plate members in tight, locking communication with the inside rim.
