Just curious, what kind of tire pressure does everyone reccomend for deep snow driving? I run 33" swampers and have had good luck with about 10 lbs. Any Thoughts?

10 lbs outta do it. Going lower you might lose a bead.
a 92 explorer is a heavy SOB so 33's at 10psi will get you some floatation but not enough for driving in DEEP snow (like untracked powder)

Without lockers you will not go far either in the deep stuff.
My BII with 35's and dual lockers at 10 psi will only go so far in the deep snow, basically it digs until the diffs are burined then thats it.

So it all depends on what kind of deep snow we are talking about.
