A 8.5" wheel might fit, but thats really pushing it. I think the offset on my Axis 19x8 wheels are 42mm, and with my 235mm tires, they barely clear the strut. They do rub in the back as well. If you did run an 8.5" wheel, you would probably be stuck with running a tire less than 8.5" wide just so you dont the rub the fender and strut. Then of course, your tires look goofy since they looked stretched over the wheel.
