The best I could find for snow specific tires is the Blizzak DM-Z3. It comes in 265/60 QR18

Little shorter than stock at 30.6 vs. 32.8" but its the tallest snow tire I can find. You could also try an A/T or M/T tire. The Nittos come in 285/60/18, again al little short at 31.4" but not bad. http://www.nittotire.com/tires_terragrappler.asp
