either way it's off to the trails tomorrow for me on my 33" FirestoneDestinations, weather has warmed up considerably up here to +6C (from -26C a couple weeks ago) and from what I understand about 1.5-2' of snow out there...so the snows gonna be a different composition than the powder I was expecting, we'll see what happens cause I'm not bringing any chains with me...just a bunch of buddies
And yes I definately believe that off road and on road are two different worlds when it comes to tire inflation...definately maintain proper pressure while operating on road...maintains appropriate handling characteristics, reduces heat build up improving tire life, and improves pounds per square inch traction....it's the off road I'm curious about...

Tire inflation in snow is dependant on the kind of snow you will be wheeling in. In hard packed snow air down to minimum PSI to increase Foot print and flotation.

In the Intermountain West (Montana, Wyoming, Utah, Idaho, Colorado, etc.), for offroad snow wheeling we air down to less than rockcrawling psi for more flotation.

With 33s, it is common to air down to 10-12 psi for rockcrawling and 6-8 psi for snow wheeling.

With 37s it is common to air down to 7-10 psi for rockcrawling and 4-8 psi for snow wheeling.

These psi levels are for offroad use only.

I have never seen someone lose a bead at these psi levels. If there is someone in our group who struggles (constantly needs a tow strap), they are always running too much psi.

The strategy in crusty snow is often to idle over it--at least with a 2 dr on 35s at 6 psi you can drive on top as long as you don't spin your tires and break through the top layers.

The strategy for soft snow is to have the rigs on 40s with lots of horsepower break the trail, followed by the guys on 37s, then the 35s, etc.

Regarding the picture below, the first rig was a 4 Runner on 39s with performance V8 (not in the picture). The rig in the right front of the picture is a 4 Runner on 37s. Then the black TJ is mine on 33s, followed by the yellow Bronco on 35s, etc., etc.
