17Inch Wheel Fitment on 66 Coupe

I recently purchased a 66 coupe, that has 17x8 rims up front, with 215/45/17 inch tires mounted on them. The backspacing appears to be 4.5 inches. The rear wheels are what looks to be 17x9.5 rims, 9.5W tires mounted on them. Backspacing unknown. These are all four Centerline Billet Hammer wheels. One problem is they rub in the rear when you hit a hard enough bump. I am planning on moving the current front tires and wheels to the rear which should help out in the rubbing department. The other problem is the 215/45/17 tires mounted on the 17x8 rims rubbed in the front when I made a sharp turn and hitting a bump ( as in pulling in my driveway). I then ordered a new pair of wheels for the front, same style, but in a 17x7 inch rim, with 4.25 backspacing. Anyone else have any similar issues? I guess my question is if I mount another set of 215/45/17 tires on the 17x7 inch rims instead of the 17x8 inch rims on the front, I would still have the same tire width either way correct? Im guessing the backspacing change might also help. Also I am not sure if it is the stock height or not. This is the first Mustang I have owned so Im not sure how to go about figuring out what the stock height is.

I sort of have a similar situation with my 66 coupe. I kept my 17x8 Bullitt wheels from an SN-95. These have a 4.5" backspacing, and have 245/45/17 tires. They don't fit at all! I see adapters from Mustangs Unlimited, but they're $270! I don't know what to try!

A 17x8 wheel with 4.5 bs and a 215 45 17 (which probably looks a little stretched on that rim) should not rub. I would spend the money having your alignment checked and your front suspension for wear. If the car has the old alignment specs for bias ply tires it makes the top of the tire tip out when cornering...you want more modern specs with some negative camber

fenders rolled?? Tubbed? How much hammering did you have to do the fit that size on a 65 in the rear?

Its fun, when it runs......

no hammering, not tubbed. just rolled fenders. I am running a nitto 275/40/17 drag radial (they run a little narrow) but they sit flush. I am also lowered and daily drive the car so no rubbing is important.
