Hey Gene, wheel choice can be dicey. I've run Wheel Vintiques 30 series Ralley wheels for years without any problems. I had 15x7 in the front with only 4" BS and BFG 235-60-15's. On the rear I had the same style/brand wheel in a 15x8 with a 4.5" BS and BFG 255-60-15. I had no rubbing problems either inside or out. Andrew is probably right about the 4.75" BS.
Thanks guys. The reason I asked was that one of my new old stock Goodyears got a big bulge on the side wall. Only 200 miles on it but it was date coded from 1968. So I ordered reproduction Goodyears. Man they aint cheep. But here is how it looks. I think I'll keep it like this.
