Cragar SS Wheels/Tires

15x 8 probably not. 15x7 4 1/4" backspace with a 255-60/15 is about as big as you can go. A few guys have gotten wider wheels and bigger tires to fit but usually not without some modifications like fender lip rolling or offset shackles or the like.
would these fit on my 71 dart? Its all stock, small bolt pattern with drums doing a disc conversion kit soon. just wondering if I would have clearance on width. I don't know much about my car yet. thanks!
