I know when I was stuck last year, all 4 tires spun together! Yeah, kinda had a little buildup under the frame...

 

I am from Colorado and Blizzak Snow tires are my faves. They are a Bridgestone tire. I would recommend them any time. Although I currently am running BFG Mud Terrains. I love them even more, maybe not on the ice.

 

Jumping into the tire discussion, I went from the stock Wrangler SR/A's (horrible) to Bridgestone Dueler A/T Revo's and LOVED them. They rode well, did great in rain, stuck like glue on ice and I never got stuck in snow....and I TRIED to get stuck in the snow. (Long story) But, I wore them out after 30,000 miles of use. The Revo 2's that I wanted weren't available, so I recently put Bridgestone Dueler A/T 695's. They ride great and work well in the rain. Give me a couple of months and I can tell you how they work in snow and ice.
