"In most mud (and snow) you want higher pressures. With the more narrow contact patch, the tire will actually dig through the loose stuff on top and get down to a harder surface below. "

Absolutely correct. This surprises alot of people. I used to have an old Land Cruiser with tall, skinny knobbies that could not be stopped. The guys with big wide tires that were stuck could not understand how this worked.
