CrossClimate 2 are good after the plows come. They are not that good in fresh, heavy snow, especially when it's more than a couple of inches deep.
Making a U-turn got 3-wheels spinning... a little backing up over the packed snow I made, and then gunning it, letting momentum do the rest allowed me to make the U-turn and back to the type of snow condition the CC2 is best suited for... plowed.

Nokian WR's are more winter focused than the CC2, and wears faster. I much prefer the trade-off of Nokian All-weathers to the CC2.
