old cragars and a 72 swinger

i have a 74 dart and have 4" bs wheels, the tire i tried on the front was a 225/70/15 , it would rub the outer fender down on the front edge when turning full lock , the sharp edge was tearing up the tread. i went and got 215/65 / and they fit fine. actually a larger bs is what i need as the front tires stick out too far to suit me.
