largest tires that will fit stock 68 Barracuda notchback

Hey! I'm in Clarksville! I think if you want to keep your tires in the wheel well you need to stick to no more than 7". I had a 68 conv. and without moving the springs 7" was the max.. I still have my SBP slots I restored for it but ended up selling the car a few years ago. My 2 cents.
