Ive done alot of snow wheeling with my truck.  I really havent enjoyed myself that much because of the getting stuck and not traction issue.  Ive got lockers in both axles and 37" tires but they get no traction even when aired down.  My idea is that if i ever wanted to do that again i would get chains for the rear axle at least mabye all four then i think it would be alot more fun
