My 1970 F100 came with 5x5.5 bolt pattern 16" wheels. The tires were g78-16 tube type. Those tires and wheels were stolen from me when I put my mags on for the first time. They lasted one night in the back of my truck before they "disapeared". Anyways, I wanted to find those type wheels again and finally did. Took me quite a while to find them. I have not mounted tires on them yet. The tire size might have been 7.50x16? Now I don't remember the tire size exactly.
