1975 Dart Sport Largest Rim Size

I'm assuming you have a 8.25 rear end, 15x10 with 4.5 backspace will fit, like the silver car, but will rub some on the wheel lip. 15x8.5 with 4.5 backspace works the best without rubbing like the green car . Silver car has 295-50-15 BFG. Green car has 255-60-15 BFG. I'm not sure about 16 and 18 inch rims.
