Rear tire width max for 67 Barracuda

I have a set of old center lines 5 X 4.5 X 8 1/2 (or 9) wide that would be real nice once I polish them out. I also have a set of matching 5 X 4 (6" in wide) for the front. I'm only asking $275 for all four!!!!!! Now that's cheap but you gotta pay shipping!!
PS - I gotta double check the widths??? I'm in no rush so take your time.

PS _ tires are no good and will be removed!
