Spare tire mounts
These are standard PCDs for trailer wheels. I needed to make a spare tire mount for a trailer I built so I made 3 of the most common PCD patterns for trailers. The holes are just over 1/2" so you can insert the bolts and weld them in place. For the larger 9/16 stud wheels, you will need to drill them larger or just modify my templates. I used 3/16 plate for these and simply welded a 2" x 1/8" wall HSS tube to the back and then welded on the trailer.
