I have been eying these tires for some time too, but not enough place
for 50mm tires on my current python :-(

On this (dutch) website:

    http://www.ligfiets.net/accessoires/type.php3?id=336

it is said that "best" pressure should be at 4bars. Bert Hoge made
rolling tests for some tires (unfortunatly I have not the article and
its seems not to be available online). And the curve rolling resistance
vs. pressure for big apple has some kind of "knik" at 4 bars
* below 4bars the rolling resistance curve decreases much with pressure
increase (i.e. not linear with pressure).
* above 4bars the rolling resistance does not decrease much more, and
above are not more comfortable.

(thats what they say on that page).
