265's if you roll the fender, 255's if you don't... Pretty plain and simple. I've got my rear fenders completely shaved, completely flat on the inside, no gunk, done professionally, and I can probably get 275's in the back, but there's really no need to spend the difference on cost between 265's/275's honestly.
::EDIT:: - Wait, you have ET33 9.5" rears? Not 9.5 Et45s? Then you're going to have to stretch that bad boy to make work, I'd say 245 max and that still might rub.
