You can obtain the same effect with the original 2.52/2.52 f/r relation using same size tires.
How do the conversion save tires ? Magic?
Or is there a logical explanation?
Do we or dont we need to cut the 4mm deiference?
you are right, truing down the front tires does not save tires, so no magic there
with the stock setting, and with the rear tires wearing out faster, the front wheels will have an over drive effect, and they car may act strange and the handling will keep on changing as you keep driving, so 16/19 give up a bit of tire life for more consistant handling, to do it or not depends on your preference
