Curious about what pressures you all are running when off-road. I typically run 60 front/ 50 rear when on-road. The last couple of trips off pavement I've run 40 front/ 30 rear. No particular reason why I chose those numbers. I wasn't "rock-crawling" so didn't air down too much. Wondering if anyone else has run lower pressures and how things went.
 
Have not aired down yet, have only been on rough forest roads in PA. My pasted vehicle had 33's. Taking 25-30% off the rated psi seemed to work well for me.

This answer will vary depending on the weight of the truck.... I have the 6.7PS so I err on the side of caution and go w/ 35 front/30 rear when doing trails like at WindRock ORV where there's a mix of conditions (rocks,mud, corrugated roads) could go lower but then you run the risk of de-beading the tire/sidewall damage in certain situations or losing precious ground clearance on such a long truck with a very vulnerable belly..... In pure mud/sand you could definitely go lower but how low, I've not tried less than 35/30.
 
Gas truck in the sand ran 14 in back and 16 in front, about a pound more than I ran in my Raptor. In our local off road park went down to 20 all the way around, but really did not need to go down that low. Next trip in will probably do 24 and 22.
 
did the rocks and sand of Utah with 20 front and 15 rear and the trail i did 23 front and 20 rear and have zero problems but if you check my thread the rear tires look very flat

 
30 rear barely caused the tire to bulge so probably a lot of room there. 40 front had some side-wall bulge but nowhere near flat. I'll try closer to 30 front 20 rear next time and report back. just thought i'd throw it out there for opinions
