Keeps the tire pressure up a little better on very cold mornings.
40 is to high IMHO. When the tires warm up as your driving they are going to be even higher.

What was the outside temperature when they were set?

The Goodyear Wrangler tires that came on the truck reflect max tire pressure of 51 lbs. The dealer set the pressure at 40 lbs. Outside temp was below freezing.

F-150 doesn't come with E rated but can be installed as a replacement set, we have E rated 265/70-17's on our 1500 Z71, D and E rated truck tires are more popular in my area.

Explorer, not BII. Firestone had a bad bunch of tires in the mix, which added to the underinflation problems.

That's right, got my vehicles mixed up, I was delivering parts to Ford Assembly when the Bll was being built
Those supposedly bad Firestones is what I was putting on my Ranger.

Anything between the door sticker 35 psi and the tires 51 psi is fine.
I'm just saying don't get carried away over what the door sticker says.

Did a check this morning when it's a little bit cooler today, and the tires show 36 all around. I know the other day after they'd been warmed up (and it was 75-80 OAT, they were showing 39 all around.

40 would be a little high. I set mine last time when it was around 65f.
At that temp, mine are around 32psi. They will climb up to 34 while driving.

If it was my truck, I would drop them down to 35psi and recheck in the spring when it warms up.

See link for Goodyear's recommendation.

Door sticker numbers are usually a good place to start. Number on the sidewall is simply where to stop.

Exactly right.

That's the max inflation to carry the max load of that tire.

Toyo publishes the load and inflation table applicable to all DOT compliant tires. Weigh the axle, divide by two, see how much air you need for the load on that axle.
