Tire Pressure
I realize this might be an open ended question but looking for your experiences. I just purchased a new 2022 F250 extended cab with the short bed. This is my first HD truck as I’ve owned nothing but long bed F 150s these past 45 years.. while it’s not surprising that the HD tires use more air pressure I was a bit surprised at just how much and that they spec running more air in the rear? My door label shows 60psi front and 65 psi rear with the Goodyear AT LT275x70-18 tires. For casual around town unloaded driving do you really run that much pressure - especially in the rear? Why does a HD require more air in the rear, especially unloaded?

The larger trucks are capable of carrying more weight on the axles. The tires must also be rated to carry more weight as well. Your truck came with "E" rated tires. Since it's the air in the tire that actually carries the load, you will need more pressure to carry the weight. If you want to work the truck to it's design limits hauling or towing you'll need to air up to the recommended pressures. .

Right but only if you are carrying or pulling a load right? 0n the half tons they recommend 35/35. I usually ran 35 fr and 32 rear unless I was pulling or loaded. Why would you run more pressure in the rear with no load with most of the weight on the front axle?

KU4OJ nailed it.
Just to add a little, there's tire pressure and working load charts you can find on Google. It's standard across the industry so they apply to any tire. You only need enough pressure for the load that you're actually carrying. Also the max pressure you see on the tire isn't even close to burst pressure, it just correlates to the maximum load the tire is designed to carry, and that is the pressure necessary for that load.

My 2WD has factory A/S tire pressure recommendations of 60F and 75R, I run them at 60 and 70 all the time, I feel like mine rides just fine.

Unloaded I run 55 psi front, 50 psi rear. Pressures checked cold. Get a tire depth gauge & measure tread depth across the tread to adjust pressure.

OP you'll see everyone has their beleived to be ride good air pressures. 65f/ 70r and I'll get atleast 50k miles out of a set of tires.

I just had Discount Tire rotate the tires I bought from them 5000 miles ago, spent 10 minutes in the parking lot adjusting pressures down after they put the rears to 80 psi. I could instantly tell they overinflated my tires, the difference in ride is very noticeable.

In my case (F-250, 7.3, CCSB, 20" wheels) the sticker calls for 60 front, 65 rear. That's where I set it when towing my 9,900# fiver and it feels perfect, but when I'm empty those pressures make it feel like I'm going airborne if I hit a serious bump at interstate speeds. In my case 55 front and 60 rear when I'm empty gives me what I consider an excellent ride. Admittedly I only have about 10,000 miles on the truck but so far the tread wear pattern looks good, nothing unusual. At the end of the day our trucks (and butts) are all different, you should try a few things and see what works best for you.

Reading for evenness of tread wear. Too much pressure and the tires wear more in the middle, etc..

Seems there is likely a phone app for this now since I watched the DT employee run his phone across the top of all four tires before putting it in the shop for a rotation. No mention of problems even at my low pressures but this set only has 5k on them. My last set wore very evenly, even given the aggressive nature of the tread.

Best method, IMO, is to get accurate vehicle weights and adjust pressures based on the tire and axle specifications. Probably can find all the information you need here https://tirepressure.org/ and/or here https://tirepressure.com/ .
