Door sticker is inflation for max weight capacity. Kind of like my truck 65 PSI in the front then 80 PSI in the rear.

 

Now doing it correct. Front axle is 4,440 pounds, and 2860 pounds in the rear. Tires are Es with 3,042 PSI at 80 PSI.

 

(4,440 / 2) = 2,220 / 3,042 = 0.72 × 80 = 58.3 PSI Front inflation 

 

(2,860 / 2) = 1,430 / 3,042 = 0.47 × 80 = 37.6 PSI Rear inflation

 

Smooth ride and no impact on performance or economy. 

 

 Now the 4440 and 2860 front and rear, are those the weight as the truck sits empty as driven daily?

Yup. One the scale it's 7,300 pound empty curb weight. Just added the two numbers together.

 I don't have a scale readily available. (other than the expensive CAT scales at the truck stops) I could guesstimate mine slightly higher, I do want to weigh it with and without the 5th wheel camper once that season gets here.

 Such a PITA to change rear pressure. I have 7 hole wheels with 4 hole shiny covers so nothing lines up to get a gauge or air chuck in there. Been looking at extenders and such for a solution.

 

The math method is easy, but usually nets a slightly higher pressure that the published load and inflation tables. I keep a downloaded copy on my phone with my tire sizes highlighted.

Based on your weights and the chart I’d personally run 55/35 summer and 50/30 winter. 
 

2nd gens are light! My 18 was 5250/3300 empty coming home from the dealership with just me in it. 
 

Now the daily empty weight is closer to 5450/3550. I run 50/25 around town in the winter. LT275/70R18.
