Not sure that all the height increase is in the tires. Often they make other changes, some of which might be needed to clear the larger tires. Now, if the tires are wider, they will pull harder on pavement, but on soft ground will cut in less, roll easier.

Larger wheels and tires put more stress on everything else, I found that out the hard way with lifted trucks over the years.
You might want to check that when talking about wheels that are not driven. Much of the stress you saw was from driving the larger tires. If trailer tires are the same width and hardness, the larger diameter will roll over things easier.
(Safety regulations require taller berms on mine roads where vehicles with taller wheels run)
