Wide tires suck in the snow and the mud. They push way too much crap in front of themselves and they don't cut through the snow or mud to the less slick surface below. I had an '85 lancruiser wagon that had just regular street tires on it and it would out-perform my neighbor's jeep that was lifted and had super swampers on it. He had the power, but no control once he got moving. The jeep, like our trucks was so light, that it could get stuck on snot!!
