My 2500 Yukon calls for 50 in the front and 80 on the door sticker in the rear - crazy.

LT tires are usually higher then 32 psi. What does it say on the tires themselves?
My door sticker says 32 psi I run 34-35.
34-36 in the 22 inch wheels. 36-40 in the 18 and 20 inch wheels.
I've messed with air pressures as well and while lower pressures work better for bumpy roads, they tend to roll under on curves at speed (only exception is overlanding/off road driving at lower speeds for better flotation and traction). Higher inflation works well for road trips as the tires heat up and expand. I find about 5 - 10 psi over the door tag works well.
I used to go by the tire sidewall (I usually got great tire life!) But the ride quality suffers depending on the weight of the vehicle. There's a reason new vehicles ride perfectly smooth........and the factory tires last 36k when put to 'spec'
Use your noodle and set something that feels right for your driving habits, vehicle weight, etc.

I was under the presumption the max inflation listed on the tire themselves was for mounting purposes.
The max inflation is the working pressure they can handle to carry the weight rating on the tire.
That's what I was reading. It says max load 80 psi cold. Not sure that is what I am looking for

I have LTs on my Express van, they're aired up to 60 psi cold. A little different then your truck, but it rides much better--for me.
