63-66 Dart. How wide of a tire on the back?

Looks like extra room. How do you like your RADIAL T/A's.
To get a bigger/wider tire under there I would have had to get a wheel with more backspace, then they would not have fit on the front. I had these wheels made with the 4 inch pattern and no way I was going to pay to make another set with more backspace. But considering I dont think you can get a wider 14 inch tire, too me no reason to get more backspacig. And I was commited to the 14 inch rubber. BFG grab well on the street. they ride good, no complaints. NO strip driving, not a race car, But no slouch either. :burnout:MT
