And then consider the backspacing of a modern wheel is somewhere around 35-55MM. Whereas the backspacing on a 1965 mustang is 120mm. Quite a difference. You'd need 4.5" spacers or something... The modern cars space the hubs out farther nearer the outer face of the rim for various reasons, packaging, handling, etc, where the older car wasn't as refined or needed that much room, whatever, so they put the hub mount in the middle of the rim. So to get the new wheel on the old car... big dang spacers. Oh, and *long* studs.

Or so I'm figuring out anyway... funtimes with wheels.

The other problem is the 7" max width of any wheel in the '64-66. Anything wider, and you start to rub things, both front and back. And since the 2015 is a 7.5", there would very much be some rubbing issues... I know because I put the widest rim/tire package I could on my old '66, and it was this: 205/65 on 15x7" rims. Translate that to 18", you'd get 205/45 tires. Getting any wider than 205 and you start hitting the frame rails/wheel tub in back, suspension bits when turning in front, if not start making body panels bend in a bounce...

I advise getting wheels/tires meant for the '65 instead of trying to fit a 2015 on it. Unless you're prepared to start cutting/fitting/welding the body/frame of the car to make them wheels work, that is, then heck yeah, go for it!

Hope that helps!
