I drive the crossfire pretty much solely in the winter now. I have 17 in rims on front and back with Blizzak winter only tires. If interested i have a video of me ripping through over 6 inches of snow. However don't stop on an uphill with that much snow. You will get stuck, luckily i tested this out in my driveway so it wasn't that bad. Over all I think even with the Blizzak tires the crossfire isn't that great. It reminds me of my Mustang GT's with the stock goodyear gatorbacks, and those are supposedly summer tires. The only good thing is the over reactive traction control. Helps at time and annoys at others. Back to the issue. Under 5 inches = no problem with winter set-up. 6 and inches your pushing it. And anything over 8 inches call into work.
