wheel and tire combo on 75? Need the cool factor!

[billschroeder5842]

I'm looking to upgrade my tire and wheels on my 75 roadrunner. It is of course a B body and currently has 14 factory rally wheels and skinny tires. I have a cool factory look but with a 75, I need all the help I can.

I am interested in an offset look; wider in back than in front.

How big can I go on wheels and tires without rubbing in either the front or the back. However, I'd rather error on the small side; I'm old enough to pass on the boy racer look for something that works.

Thanks!
