Tire pressure
#11
Max tire pressure is for carrying the max load. Heavy duty truck tires(f250/350 type trucks) have very high load capacities and need tires that can handle it. My work truck's tire max is 80psi and I run them at 70.. it rides like total crap but it is hauling heavy trailers, tools, and a 100 gallon diesel tank around all day. The 20,000 pound Freightliner tires run at 105psi, you get the idea.
On a light Jeep these beefy tires can be run at lower pressures and support the jeep more comfortably.

You have to keep in mind that a tire is meant to be used on a variety of vehicles.
For example my 2500hd crew cab has 285/75-16 duratracs and our JK has 285/70-17's. Same max psi rating but I run 50psi on the truck and 30 on the JK. Only because the truck weighs sooo much more.
Hope this helps.

37's and Tire Pressure
Putting 37's Trail Grapplers on an Expedition Modded rig as we speak. I went with the Nitto's on your reco WOL, based on the sidewall strength you mentioned etc. My JKU has a lot of extra weight. AEV front bumper and Warn 9.5, AEV rear bumper with gas storage (plus 5 gallons of potable water in the bumper), 60" hi-lift, pull-pal, gobi rack with 135lb Maggiolina RTT with 30lbs of gear inside, ARB fridge and 2 drawer rear area only storage. Full armor underneath, and a few other things. What air pressure do you think I should run the Nitto 37's at with all that extra weight?
I'll be on beadlocks with on-board air for off-highway.
Thanks in advance.
