I just purchased a set of Trailhead tire deflators. I ran my last Jeep off-road at full hwy pressure. ( only took it off road twice) I decided to get some tire deflators for all future runs. I now have an 07 Unlimited Rubicon with stock suspension and stock tires (255/75r17) BFG Mud Terrains.
The question I have is what would be the recommeded (by you guys) tire pressure for off roading. Conditions on the trails vary: mud, gravel, rocks. Nothing severe but all fun.
I have a deflation guide that came with the deflators, but it does not have my tire size on it. the closest is 285/70r17. The guide shows that tire size with a gvw of 4000 to be 12 psi and 5000 to be 14 psi. Is this a good setting for my Jeep with the tires I am running?
Yes, I did do a search, but could not find what I was looking for.

Run your tires round 10-12 psi. They will be fine there. I run my tires at 8 tho.

Thanks, Now I know where to set my deflators at.

Yep, you should be just fine at 10-12psi. Grippy too!

Hell I run my tires at like 15 alot of the time, I go lower if I need more bite but its surprising how grippy BFG A/T's are;)

I run the following pressures:
Street pressure: 28 psi
General trailing: 12 psi
Wet/muddy conditions: 10 psi
Snow: 8 psi

I run the following- 25-28 psi depending on the day out on the street-
8psi every time it sees trails :D will be going to zero here soon ;)

For your tire size, set them to 12 to 14 and go.
Only need to risk (risk = popping a bead) if you need more tire flex for traction. From your description, you are mostly airing down for ride comfort anyway.
