Wheels for 66 barracuda

I have run 15x7 rear wheels with 245/60 tires on a lowered 66 Cuda, no rubbing unless more than 2 people in the car. I currently have 17x8 rears with 245/45/17s with a custom offset, a bit of rubbing on the outside if cornering hard on the track but not under normal driving conditions. The bigger wheel look might not be for everybody, myself included on some, but there are really no choices for decent tires in 14" or 15".
