Depends if you want to try to stretch or just want a smaller side wall. Doubt you'd have much luck trying to stretch on such a narrow wheel, but you could go down to a 195/45 or 195/50.
Play around on that website a bit as well, might not find much without looking for stretch, but google will also help. Just type in your wheel size and the tire size you're looking for.
Also depends on what ride height you plan on running IMO.
