Tire pressure is just super odd to me. The door jam would apply to factory tires, but off-road, at tires are completely different and can’t really rely on those numbers.
On my toyo it just shows max pressure of 80psi. On initial install, I had them on 40-42, and it was a stiffer ride. Aired downed to around 36 and seems to be much better.
I’m going to lean on what half of the max pressure listed on the new tires, then air down or up/chalk test as needed for a softer, better ride. Summer and winter changes those numbers as well...depending on where you live.
