I just went to 15s (covered in another topic). I went with BFG 225/70/15 and I am very happy with the look, ride, feel etc. I think they fill out the wheel openings nicely. Just a note, the right front does rub just a bit if wheel is cut all the way to the right. The car rides much nicer IMO with the 15s. As you can see in the pic below I went black wall out and no trim rings (for now)...
