I plan on replacing the small bolt pattern Cragar SS wheels on my 70 Dart for a different look. I am going to be swapping large bolt pattern axles and brakes on the car and then I'd like to put Wheel Vintiques Magnum 500's on it. I'd like 15x6 for the front but it appears I'll have to get 15x7 as 15x6 aren't available. The Cragars on the front of my Dart are 15x6 with 205-70-15 tires which fit just fine with no rubbing issues. My question is, if I have to go with 15x7 Magnum on the front, what size tires can I run without the risk of them rubbing? I would like tallest tire possible as I don't like short tires but at the same time, I don't want a tire that is narrow to the point where it just fits on a 7" wide wheel and the sidewall is flush with the rim (if you know what I mean). I believe my 205-70s would look like that on a 7" wide wheel so a 60 or 65 series tire seems likely. If anyone has 15x7 on the front of your car and could post a pic and tire size, I would appreciate it.

Sorry but your car looks perfect with the combo you already have, and you have answered your own question as 15x7's on the front will make you buy a smaller tire than you already have, you will be lucky if a 195 will fit...

Just tired of looking at Cragars. I've had quite a few cars, most of which had Cragars on them. I would like something different for a change and I have always liked Magnums.
 
What brakes are you using for the BBP conversion in the front?

You can run 225/60/15’s on 15x7’s in the front if you can get the right backspacing, but that will depend on what disk brakes you’re going to run. If you run the 73+ Mopar BBP disks you need a 15x7” with about 4.25” of backspace to clear 225/60/15’s.

Yes, I have a set of brakes from a 73 Duster.

Ok, then with those brakes and a 15x7” you need a 4.25” backspace and you can run 225/60/15’s. If you run less backspace than that, you’ll have to run narrower tires. The issue is that a lot of aftermarket 15x7’s only come with 4” of backspace. With 4” of backspace on a 15x7 a 215 is pretty marginal for clearance, it can be done but it will depend heavily on your ride height and the body tolerances on your car specifically.
