X-Ice/Blizzaks WSXX
I put 120 pounds in the trunk.

 

Speaking to you all from the hellish white that is now DFW, after a 3 hour trip home from work last night and an aborted trip to work this morning, (I-35 in Carrolton had all the overpasses shut down) I can report that while it is not for the faint of heart nor is it easy, I can navigate the worst the metroplex has to offer in my 'Vert. 3 inches of polished ice on every surface means you're drirfting, not driving. It was draining and frustrating. But my girl held it together. Not one spin or a spot I got stuck in.

 

Thanks Toxix for the link on this. I guess 120# is the way to go.
