I was running 18psi in the JK and the Nissan was also at 18.
I'm not sure what the PW was running.
There was plenty of deformation even in the cold temps.

WOW, did they get stuck a lot at that PSI? I'm going to guess yes.
I've seen this on sand and snow where someone says they are aired down enough, but are working their vehicles hard, I finally convice then to try droppign their pressure to 10, 12, even 15... they are amazed at the difference, I'm sure you all know this already, it just seems 18 is very high pressure for snow, unless on a 7000+ lb truck with load E's that are normally 90PSI on the road
one time out on the sand dunes me and a friend lowered teh friends brother's tires from 15 to 8 because he woldn't believe it woudl help and was complaining he needed to upgrade to a V8 in his 85 CJ7, he then drave around the hill and back up to the top, smile from ear to ear jumped out and said "Damn, I'd swear you guys just did that V8 swap for me".
Needless to say, he was amazed.
BTW, looks like you guys had a great time, I can't wait to get out in the snow with my TJ. Snow runs in MI are some of my favorite weekend trips.
