Jefe is spot on with his analysis as well.
To add to it, just like many things, there is a balance depending on conditions. Same goes for winter driving. More tread contact vs more ground pressure vs type of tires vs type of snow vs just ice.....on and on.
Like adjusting your wdh. Not a prescribed set of instructions that will work every time. Depends on vehicle capacity, tongue weight, length of trailer, axle placement..........
Some snow/ice is very challenging to drive on, like here on the wet side. Some is like driving a gravel road, when it's 30 below, snow and ice is almost "sticky."
