73 Dart Swinger wheel/tire combo suggestions?

I also have a 1973 Dart Swinger. I have 225/70-14 on stock Mopar wheels (look like Magnum 500's).

Suspension is stock and they fit well, fill out the fender wells, and do not rub anywhere. I can't send you any pictures, my car been in the body shop for almost three month now eating up huge amounts of my hard earned money.
