Tire pressure
Just replaced tires/rims from stock 18 inch to Bridgestone 275/65-20. Tire/rims came installed and balanced with 80 psi in them. My stock tires were recommended at 65psi. Max load inflation psi on new sidewall is 80psi. I dropped to 65, but curious what others run in their 20”s when not loaded or hauling. Thanks…….Tonebone

An F-250 with 20" wheels has a suggested psi of 60 front/65 rear(tire max 80). But that is based off of the maximum capacity for the 250. Unloaded they can be lower. I aim for around 55 all around on my unloaded diesel 250.

Yea, I have the stock 20s.
I run 65 front and 60 rear.
I run the rears lower because the rear of an empty truck is a lot lighter than the front.

When I first got my truck, September 2021, about 4500 miles ago, I thought the OEM tires were quite "hard" and could feel every little crack in the road. So I let some air out, about 5 pounds under what the sticker called for and the ride seemed a little better.
Now that gas is outrageously priced and I'm trying to squeeze every MPG I can out of this thing, I pumped my tires up to 65 front and 75 rear, a little over the sticker. This didn't seem to diminish ride quality any. So I guess it takes a little time to soften up the sidewalls a bit. Or my butt has become calloused.
So you may revisit your pressures after the tires get broken in a little.
