I've had these tires on for about 3 weeks. First ride was in mud about 6-8" deep. No problems whatsoever. Transitioned into snow on the same day. Again, no problems. Second trip was in snow that ranged from a few inches to a foot and a half. Great traction. Don't get crazy on the throttle...these tires chew up the snow...you'll find yourself buried real quick. GREAT TIRES! Very satisfied with the purchase.
