My plan for new wheels, what do you think?

I have a 68 Dart GTS and does anyone know if a 255/70/15 using a 15 X 7 rim with a 4.25 backspacing with stock suspension work or will it be to close for comfort

I'm going to say no. A 245/60-15 would not even fit on my '69 GTS with 7" wide 4.25" backspace wheels. They were just about guaranteed to fit by most internet "experts", but there isn't physically room for a tire with a 10" cross-section on my car, no matter what wheel I used.
