What tire pressure are you running?

I usually run 34 psi front and 38 psi rear. I'm willing to sacrifice tire wear for comfort, but my tires have worn pretty evenly anyway.

Would help to also specify tires. I run BFG MT 255/85R16's . I run 32-34 all around.

40 psi all around for over a year now on new Good Year Wrangler DuraTrac LT235/85R16 E load range. Very happy with ride and wear.

33ish front 37ish rear. I felt it improved the handling and made the slight bobbing front to back on interstate gaps/road go away. I was running 40 all around originally. 265/75 BFG AT with OEM rate/height springs, Bilstein shocks, Superpro bushings, F&R sway bars

On the beach I don't really have to drop for traction but when I do drop I go to 18-20 all around.

That is the exact same I run on my 110 CSW. 235/85 R 16s. Smoother ride and I almost never air down when off road as well 👍👍

Running 40 psi must be why I get constant 28 MPG. :D From the factory my LR4 had more psi than 35 psi in the rear I remember correctly.

For my Tithonus I'm on BFGs 235/85/16 AT KO Load E. Running them 33-35 all around but may increase the rear. Interestingly, my tith handbook has the tyre specs (converted from bar) at 27.5 front and 42 rear for XZLs.

My D90 SW is 28 front, 35 rear on BFGs 165/75/16 AT KO.

x2 Above 35 for me isn't worth it and often ends up causing something to rattle loose.

Contact patch on your tires is how its supposed to be done. Too high and you wear the centers prematurely. Too low and you wear the outers prematurely.

Tire construction varies considerably by brand and size and model. Just because a load range e tire says you can run a high psi doesnt mean that is whats right for your application. These are light trucks and unfortunately the tire sizes a lot of us like to run are now only made in load ranges C,D, and E which is total overkill and thats not necessarily a good thing for ride quality and road handling. Stiff sidewalls make for harsh ride and poor road handling on a light truck.
Load range rating of C for instance is 1800 lbs per tire ie rating for a loaded truck weighing 7200 lbs.

There is a two digit number after your tire size on the sidewall. This link translates that load index number into an actual lbs per tire load rating for you.
