I have a set of 8-lug wheels from a '78-'79 F-250. Two of them have "roller" tires that hold air well, while the other two have no tires at all. All of them are very clean, with essentially no surface rust. A quick scuffing and some paint and they'd look great, or just bolt them up and use them. The discoloration in the photo below is just water from the melting snow, not the paint.
I'll sell them for the same $60 I gave for them. Located just west of Grand Rapids.
