Recently purchased a '91 Chevy G20 Sportvan Beauville. It currently has 235/75/15's on it, I'm finding out it can also hold 225/75/15. I'm wanting to possbily do a smaller tire in front and a big one in back.. it is a 3/4 ton, and its a long wheel base. I'm honestly not sure if it would look good, or even be practical to to and get the front end to scoop a bit. Any advise is welcome, this is my very first van ever, so please feel free to chime in and give advice.
