Ive been driving my crossfire on 17" inche wheels with blizzak 225/45/17. Only got stuck trying to push the snow with my crossfire the snow was higher than my foglights. Almost made it. With a faster running start it went through without a problem. No problems since the blizzaks make the car a lil' snowmobile. Got my setup from tirerack, set me back 1200, better than buying a beater that will end you costing you more money in the long run, trust me on this i know, buying a beater is like playing Russian Rollette, with 1 chamber empty.
The car has had no problems since i have put on the 17's and the ride has gotten much better.
