Got the X5 just before Christmas, one week later the biggest snow storm in 12 years hit. In 30hrs we had 29 inches of snow. Not much was moving, but the X5 with all season tires plowed through the snow like a hot knife through butter. In the past 26 years in the Sierra Nevadas I have driven most types of 4x4's, and the X5 beats them all. More snow is on the way. I wonder what it would do with a good set of snow tires!
