LT tires on a trailer should be filled to the max pressure on the side wall.
On a vehicle, the best answer is to contact the manufacturer of the tire, but 35 PSI is way too low and will cause excessive wear.
And after the “air em all up” recommendation, you come in with the just as wrong recommendation the other direction! Roflmao
OP you analyzed everything and you got the right answer yourself.
Those weights those tires, 35psi +/- for normal driving is right.
Load up the back, air the rear tires up a bit.
Winter/snow, less psi = better traction
Summer/ towing/heat , more psi = Better handling and cooler running.
All within 10-15 psi or so of 30 for that weight and tire.
You’ll never use all the capacity of those tires. Which is great, they last longer and are tougher.
Getting into the finer points of what is too much and too little air is another discoussion.
But old wiz is 100% wrong.
