I think I used to air my Duratracs down to 15 on the trail. My MTRs run 12 on the trail.
I run my tires at 35 on the street and usually about 15 on the trail (285/70/17 duratracs and MTRs). you don't need to worry about popping beads until you get down close to single digits.
even if you're not sure how to reset a bead on the trail, you all carry a full sized, matching spare when you're out wheeling, right?
I have a 265/70r17 ... dont know if I can fit a 285/70r17 on the rear

I read a Jeep club's "requirements" to participate in their trail rides and they listed a full size spare with a diameter no smaller than 3" less than your other tires. With 285's I plan to keep the regular spare. If you're not on an overland trip, you'd think that would be fine until you can get back into town and get your main tire repaired.
^^^^When I had my duratracs I was running 40 psi on the street and about 18 on the trails.
