I have a 1951 gmc 3/4 ton pickup the tires and wheels that are on it are (not original) are 8 lug 16 inch tires on split rims. I also have a set of 8 lug 16 inch rims and covers that I was told were originals it appears that these are two different widths.
Regardless of that the covers will not fit on either. Did the 51 3/4 ton have covers on the rear wheels? Are the rear wheels and front wheels different widths? I would like to put wide white walls on is this original?
