Tire sizes????
This probably isn't much help as I don't remember the offset, but I ran 255/60 on my '85 LX back in the day. I kept the quads, and had no clearance issues with either the quads, or the fender lip. At the time, I was using the stiffest control arms available (South Side Machine) and relocation brackets. My quads were worn out, and even with these control arms, I was getting some hop. I replaced the quad shocks with some aftermarket ones, and that was the end of my wheelhop problems.
They were just a generic (cheap) set of 15X8 cast 5 spoke wheels. I believe the company was Sendel. I wish I could remember the offset/backspacing, as that would be of more help to you.
