57 chevy rims and tires

[jlohrunner]

This is probably a pretty simple question for most of you, however I need some help. I am working on a 57 Bel Air and was wondering if anyone knows the widest set of rims and tires I can fit on the front and rear of my car. I do not want to mess with the fender wells or tub out the car. Right now I have 15" 205's on the front and back. Ideally, I would like to have the widest possible tire in the back with a large side profile and what ever will give me a traditionall hot rod look on the front. I have allready decided on cragar ss rims for the car. If anyone can help I would really appreciate it.

p245/60r15 are in the back of my 57 there is about
1 inch clearance between tire and fender,when i take
the tire off i have to put jack stands under the frame
and let the rear end hang down to remove the tires.
i run a smaller tire in front 215/65r15 you can go
bigger but i dont know how big on the front.
