I have run across a pair of 16 inch rims, GM 6 hole, but they are definately 4 and a half inches wide inside to inside. One appears to have three stripes, but I think they are a repaint from ages ago. I have looked in the specs from '36 on and find no reference to any wheel passenger or truck at 4 and a half inches wide. Any ideas??
