Tire size for fender well headers??

It`s been many years since I had a big block A-body with fenderwell headers but I remember having issues with the E-70/14`s that were on the car. Going in a straight line was never an issue but even on slight turns they would rub. I can say on my car I would have had to go smaller than E-70/14`s to prevent rubbing but each car/headers will have to be looked at on an individual basis. Let us know what you come up with.
