For example, if you could balance a trailer on the two axles, if you tried to lift the trailer tongue it would not get lighter as you lifted but heavier as the balance/pivot point would shift rearward. Think of a teeter totter.

Hi

You are partially correct but only in reference to tandem axles.

Us the example of a single axle trailer with the axle mounted in the middle of the trailer. The higher you lift the front the lighter it gets until you reach a balance point or the rear of the trailer touches the ground.

A trailer with tandem axles the suspension does the same thing as a single axle trailer until you reach the limit of the bogie in between the 2 axles.

So the initial lift of the front of the trailer will cause a weight transfer to the trailer axles and the front would get lighter.

But again a lift of 2 or 3 inches will not reduce the weight at the front very much and may not even be evident using a truck scale.
