Tire fitment 68 Dart

With a 15x7 and only a 3.5” backspace you’re going to have a hard time.

I ran 225/60/15’s on a 15x7 with a 4.25” backspace and that was the limit on my Duster. If you have SBP brakes a 225/60/15 might work, but a 235/60/15 isn’t just a width problem, it’s also pretty tall for the front. And I don’t think a 3.5” backspace will cut it.

If you’re BBP up front then 215’s are probably beyond the limit already.
