I'll echo the calls for a 235/40.
I'm on my third set with my RX-8 wheels. They might kiss the inner fender lip from time to time (under VERY hard mid-corner bumps, or when the back is fully loaded), but I have no actual fender damage to prove it (just some strange wear marks that show on the tires from time to time) and I can't say that I've ever really felt/heard any fender or fender liner contact.
I have a fender roller, but I've never gotten around to rolling my fenders. I have the stock wheels/tires back on right now (warranty work) but I think I might give the fenders a quick, mild roll before I throw the RX-8 wheels back on just for good measure.
