245/60/15 tyres on 69 Dart
The backspacing of the wheel is definitely the key to getting more tire under the car without modifying anything. Wheel Vintiques made my 15x7 small bolt, rally wheels with (if I recall correctly) a 4-1/2" backspacing. I have these on both the front & rear of my '71 Scamp with a set of P235 60 R15 tires, & they've never rubbed or scraped anything. I think I could go slightly wider in the back, but I'm content with what I have.
Sorry I don't have a pic directly from the back, or closer to the wheels, but this one gives a glimpse of the wheel lip of the quarter.
