there are a couple of guys who have 20's laying frame with A/C but I know anything bigger than an 18 and you will most certainly have to notch the AC and possibly move it up a little bit more, I don't remember exactly what those guys do. I know there is a write up on RPS though.
If you don't want to do any of that you will still need a real small tire on an 18
