I have 8" wide 18s with a 50mm offset, and they just barely make it. Dont think you would make it without widening the fender
If you really like the rims, you might be able to take them to a macine shop and have 1mm or 2mm milled off the back side of the wheel to hub surface. That could get you enough to make it. Just a thought, and not sure if that would make the wheel weak.
