It all depends on what all season tires you have on there. I live in the mountains and driving through a foot of snow is normal. We got around fine on the stock BF's. But our Xterra also has the rear LSD, which helps. This past winter the tires were down to about 20% tread. I never got stuck but it wasn't ideal. As long as you have a good amount of tread left and it's a decent tire, you should be fine.
