I have a '78 Camaro rear end with 15 x 7 wheels. Wheel backspace is 4.25". Tires are 205 75R15.
I occasionally get a slight bit of rubbing on the box sides - just enough to make a mark without removing the paint. I don't think that tires 50 mm wider than what I have now would fit without modifying the fenders. (I'm presuming that the 8" wheels will have a 4.5" backspace - you need to confirm)
