I run a set of these on my X. I'm using the stock size, 265/75/17 (or whatever comes with the 07 OR version). I absolutely love the tires. I drive a LOT in the snow, and have never had issues. I'm always blowing past people on the highway in "slick" conditions, because, well, they aren't slick for me. I have a few miles up some back roads to drive home in the snow as well, and they stick to that stuff like glue compared to any other tire i've had (I've never used the BFGs). If you look at tirerack.com's user ratings, the goodyears edge out the BFGs in a couple of categories and loose in a couple of others. The only category that had a significant difference was the ICE traction category. That was one of the tipping points for me. The other was the price - they were cheaper. The third reason I got them was that they are less popular with the offroad crowd, and would be less likely to draw attention and possibly be stolen. I highly recommend them.
