i have 9" in the rear with +20 which sticks out about an inch
and i use 215/45 so if you want it to clear i say anything above +25 should be good with that setup

8.5 +45ish with a 235/40/18
9.5 +55ish with a 265/30/18 (or is the right size 265/35/18?)

You might need to roll or just shave your fenders a little.
