I solved a rubbing problem on my '66 Dart by rolling the inner fender lip. Put a baseball bat between the tire and the lip (protect the lip with a rag if you don't want to scratch the paint) and roll the bat back and forth to force the lip against the outside sheet metal. I'm running 225/50R16 tires, which are a little shorter than yours but slightly wider. I've got the ride height set low enough that the tops of the tires are just barely tucked into the fender.
