I posted this on the safe tire thread but it's something to consider...
If you need new tires, consider going to a narrower tread. My stock size is 265x70x17. I'm running 245x75x17. They're the same diameter and load rating but an inch or so narrower. They handle better on slick roads and in rocks plus they leave more clearance for tire chains. Their one disadvantage is that they will dig in a little deeper in sand, which isn't a problem here.
