ABSTRACT OF THE DISCLOSURE A rim is disclosed for converting a vehicle wheel into a dual wheel. Different sizes of tires may be mounted on the rim, so that the rim may be used in con- nection with different vehicles having different sizes of tires without having to obtain a new dual rim each time there is a change in the vehicle tire size. The dual rim includes a cylindrical drum having a fixed rim element located adjacent to an outer peripheral edge of the drum. An adjustable rim element is slidably located on the drum for axial movement away from or toward the fixed rim element, thereby accommodating different sizes of tires. A plurality of hoop-like concentric retaining elements are attached to the drum outer surface and are axially spaced from the fixed rim element at predetermined intervals. The adjustable rim element selectively engages one of the retaining elements depending upon the size of the tire used and the adjustable rim element is clamped in position. Chain type releasable fasteners are connected between the drum inner surface and the vehicle wheel to releasably hold the dual rim in position.
