Abstract: A tool to facilitate the mounting and centering of dual wheels on an axle hub and the method for using the tool. The tool is a pin structure having coaxial female threads at one end, allowing the pin to be attached to the threads of the lug bolt, serving as an outward extension of the lug bolt. One or more such tools are attached to lug bolts on the axle hub, providing a pin or pins upon which the two wheels may be placed sequentially. In this configuration, the two wheels counteract and hold each other in properly centered orientation while they are fastened to the axle hub with lug nuts. After the dual wheels are fastened in place, the pin or pins are removed and the lug bolts to which they were attached are also used to fasten the dual wheels to the axle hub.
