I plan on using the GM Dura-Tracs that are on the truck. Missouri winters are more mild than Ohio, which is still more mild than Wisconsin or Canada I imagine. But I've never had a problem with an AT tire on snow, or ice for that matter. Granted, only studded snow tires work best on ice, but a good AT on a 4x4 will allow you to at least GO on ice....it's just the whole STOPPING thing that leaves something to be desired

Missouri like I said is more mild, so it seems like they get a lot more ice than Ohio did when I lived there.
I like driving in the snow usually. I remember when I still had my 2004 Duramax, we had got a decent amount of snow and I had nothing else to do that night, and no one was on the roads, so I went out and played around

The few people I did pass gave me a weird look as I drifted around the corners. Wide open parking lots are good for doughnuts too. I dunno, I've driven on the snow enough that I guess I've learned how to drive even with just 2WD. It's mainly the other people on the road you have to watch out for.
Talking about tires though, I just got some new ones on my company pickup; Hercules Terra-Trac AT 2's. Like the tread on them a lot. I had these tires on my 2004 Duramax also. They are very quiet as well. Like that a lot.
