Margin is a percentage of the per tire rate based off of axle weight, so if you want 10% margin than it will add 10% of the weight to the tire position, and increase the suggested air pressure. So setting to zero just calculates off of the axle weights. I normally give myself 10% margin, I think the tool had 20 as the last input I tested.
So it is just as safety factor that you can add in, to the equation.
