On this site search “tire and wheel fitment guide”
There is a list of compatibility for tires and wheels, sorry  I don’t know how to post the link.

UO !!..UO !..ME !!!.......ME!!!.....call on ME!!!!
I have 15" on my 66.
215-65-15 all the way around. I had previously rolled the fender lips so no scrub.
NOW...I have Torque Thrust rims and I'm NOT sure of the width/BS.
I previously ran 225/60-15's with no issue. The front springs have been cut 1/2 coil I think...
No major scrubbing then except when trunk was loaded and cruis'in 70+ and hitting potholes in Okla.
Hope this helped a little......

15x7 with 4.25” backspacing and 215x60/15 will fit with no mods.
15x8 will not fit unless you like rubbing.

I have fitted a out every size wheel and tire combo imaginable n my 66.  I can tell you from my own personal experience what fits. Those fitment charts are not real world. Like Sal said:  “fits great but it rubs”  no further comment on that is necessary.

American Racing Torque Thrust 15x 7 has 3.75” backspacing and does not fit well. I would run them if they made it in the correct backspace.

I will take your advice (and Mike (Sally) also and look into the 215/60/R15 size and if they come in white wall stripes. Thanks guys for the input.  -  One more question - would a 215/70/R15 fit also or would there be problems?

The big advantage of a 17 vs 15 is the 17 has less sidewall bulge. That bulge is usually where the rub occurs.

We put TT-D 15x7 with 225-60/15 on the back of Jose’s 65 fastback. Those wheels have 3.75 backspace and typically cause issues. But, on his car, we installed a Maverick 8” rear end that is 1” narrower than the Mustang original rear. Having the extra 1/2” on each side made those wheels fit perfect. That said, the best backspacing for a 15x7 equates to 4.25”, which is, effectively, what his car has.

I think I am opting for a set of 15x7 with 4.25” backspace reproduction Shelby 1965 wheels for my 65 convertible. I will use 215x60/15 tires because they fit best with no potential for rubbing. Also, a lighter tire helps drivability and handling. Bigger on the street is not always better, but 99.9% of the people will argue with me on that statement. I am just applying fifty years of Mustang ownership knowledge and putting it to what I think is MY best use.

Your mileage may vary!

Not to beat a dead horse, but I am still searching for the right combo of wheel, wheel backspacing, wheel width and tire size to install on my 65.
Everything is stock as far as brakes and suspension.
I currently have the original steel wheels and am running 205 70 R14 tires with no issues and also, non power drum brakes. No plans at the moment to do any brake mods.
I am looking at two options for wheels - the styled steel wheels with the red center caps in 14X7 with 4.25" backspacing with a 205 70 R14 skinny white wall tire   OR
the styled steel wheel with the red center caps in 15x7 with 4.00" backspacing with a 215 70 R15 skinny white wall tire.
Which combo would work best or would either one work without issues? This would be for a nice sunny day cruiser that I don't plan on driving hard.  - That's what my 68 is for.
I did try searching for a skinny white wall 15" tire in 215 60 R15 - but no joy - and no plans to up size to 17" wheels either, and don't want the raised white letting too - so the BF Goodrich Radial TA's are out.

What do you experts say? TIA
