    Door jamb pressure. I thinks it's 26psi on my 99. Works fine for me with 285/75/16 E load Toyos.

    In my humble opinion, the "door jamb" suggestion is too low. I feel they want 26lbs. to achieve a better ride quality on our trucks as they are inherently stiff riders.
    So my way is to strike a balance between the door jamb number and the max inflation number on whatever tire I am running. The Michelins I have now say "35lbs. max" so I keep them right at 30lbs.
    I bought these tires in 2014 at 120,891 miles and just turned 140,000. That's a little over 19,000 miles on these tires. They still look like I just bought them last week.

    Too many variables, load range and weight of your truck being the biggest. Chalk test for street driving. Experiment with different pressure offroad. I generally start around 13psi for most of my offroad driving with E range tires and 2000lbs heavier than a stock truck. In snow I've been down to 7ish without issues

    Doesn't get too harsh on the street? I haven't tried 45 but when I first got my truck, the dealer had the KO2s inflated to 55 psi all around and I thought I was going to die on the highway, every little bump especially on a turn made the back end feel like it was going to fly off to the side and I would crash. Brought them down to 35 and it was 1000x better

    edit: this was also when the truck had stock suspension so that could've had something to do with it, but with a lift I feel like it might make it even worse

    yeah the C rating probably helps a lot, mine were E so they were harsh to begin with

    That's not a good way to do it of say running 50psi or even 85psi max psi tires. You only add pressure based on the weight of rig. So your just giving yourself a stiff ride for no reason.

    yeah the max PSI rating on the sidewalls isn't a recommendation, haha. It's just the maximum PSI you can run before you risk blowing the tire. I wouldn't run my tires anywhere near the max PSI rating

    My chalk test wanted me to run 20psi. With the highway driving I keep it at 26-28psi cold.

    12psi on the trail.

    Wow. What tires?

    That sucks to get good wear you need to run them so high. Like riding on bricks
