Tire pressure help
I have a 2019 f350 6.2 long bed. I just installed 295 65 20 toyo at3 tires on it and tonight had the first opportunity to take it for a lengthy ride. The installer has my fronts at 63 lbs and rears at 81 lbs. Comparing it to the Michelin at i took of the ride seems a lot harsher and at times a little squirrelly. My question is what is a good pressuer to run this truck at? I dont really tow anything nor have a significant amount of weight in the bed. Any help would be great

I run 45 front and 40 rear when unloaded. changed values in forescan to get rid of the low-pressure light.
I'm running 37x12.5 ridge grapplers and the ride is MUCH better with the lower pressure.

You should be fine at 55psi all around. You can always adjust the thresholds using forscan. My buddies 19 alarmed at 50 psi but that is where he likes to keep them so he always got the warning. I changed his thresholds for him to get rid of the idiot light. The tears might alarm at 55.

Download the Toyo load and inflation table, weigh your axles, divide by 2, and that's what they should be.
I always run my fronts at what the door sticker shows, and the rears about 5-10lbs over what the load and inflation table shows for my weight in case I pull a small trailer or something.
When I pull heavy, I inflate all tires to max.
