In my silverado, theres almost no weight on the rear tires. I put 35psi in the front and something around 32 in the back. What do you other truck guys do that don't tow or haul anything on a daily basis
Tire pressure Question

Those are the pressures I run on my Tacoma; Michelin LTX M/S-2 tires. Those pressures give me the best/most even wear under normal driving. I do increase the rears a little if I load it down.

I can't even imagine your tire pressure gauge is accurate to within 3 psi let alone that little variance making any difference in fuel economy or ride comfort.
It may not be that accurate, but should be precise enough to measure the pressure differences. I've found that just a few PSI can make a noticeable difference in ride and handling.
I go by manufacturer specs within the manual and not the door label.

We have a bunch of Silver's out there, most running the factory 17 inch alloys with a 265/70 sized tire IIRC.
If you are empty I prefer about 38 psi front and 34 rear, seems to really even out the handling and treadwear for us. But then you must increase the rear pressure when hauling stuff!

The vehicle and I do know that the door label came from the manufacturer but I've seen, at least with some foreign makes, the pressures on the door label were higher. The suspicion is that the Firestone / Ford fiasco caused the manufacturers to recommend higher pressures for US cars out of liability concerns and it's cheaper to produce a door label rather than update the manual.

I used to do the same thing with an old F-250 I had. I always ran the recommended 51 psi on the fronts. On the rears I ran 80 psi as recommended when loaded, but I ran 35 psi when empty. It made it bounce less and I felt that it improved braking.

Whenever my father brings his 2001 F350 to the dealer for an oil change, they inflate the tires to 80PSI. Makes it ride ... interesting ... and driving in the wet (empty) is dangerous.

Its significant difference in PSI
I've also noticed in BMW's that they have different PSI ratings for regular driving or carrying heavy loads. For pickup truck owners we really could use that. I'm experimenting with rear tire pressures on half-tons since they don't see everyday heavy loads despite the door sticker recommending 35psi (and front requiring really low PSI.)
I tried 29 or 32 psi in the rear tires. 32psi for occasional loads/dry seasons, 29psi for wet seasons trying to minimize wheel spin.
