tires again... two sizes, unusual but does it matter?

Interesting about the weight shift during braking. Hopefully we are talking about the trailer suspension equalizer and not a hitch equalizer. Not sure I understand how the brake event cause the weight "lift" in the equalizer of the suspension. My thinking was that it would reduce / slightly lift the rear axle.

I am also wondering if there would be any affect on tongue weights with the larger tires moved to the forward axle.
