Chevy dually load range E tire pressure

10,600 lbs gross with 235/86-16 E-rated tires, RAW 6,850lbs, FAW 3,750lbs. Fronts at 50psi and rears at 60psi, and that's 5-7 psi more than manufacture load-vs-weight inflation.

The S&S is just over 4,500lbs ready to camp

It is everywhere but on rvnet. Where people have been complicating the simpler things in life since 2003!

Is not the max weight rating of a tire at the max pressure listed on the sidewall of the tire, ex. 265/75/16... 3415 rating @ 80lbs?

I drove on scales with my TC and about 5000 lb of camper + 120lb generator on front hitch calculated to 70 psi front and 60psi rear.
I added 5 in the rear as safety precaution.
Without front load it would come to 65 psi all around - aluminium bed that is about 300 lb lighter than steel.

If you were to load a DRW truck at the rear tire ratings, your rear axle would be carrying 50-60% more than the axle is rated for and the GVWR exceeded by 80-100%. There is simply no argument that such a load could ever be safe. DRWs have a lot of excess tire capacity

Jeeez....Read what I said and note at the bottom of my reply I said "like my truck".
My older 3500 drw has LT225/75-16 E tires at 2470 lbs capacity for "dual application". Four of them = 9880 lbs total.
This truck also has a 8200 rawr.
Now having said that I have no idea what year model one ton DRW truck your talking about.

So the card on door jam is tire pressure fully loaded?

Yes, it is fully loaded. This will cause slightly more wear in the middle of the tread in situations where the truck is not fully loaded, but it is better than being underinflated.

If you want to be spot on you need two things:

1. Actual weights on each wheel.
2. Manufacturer's inflation chart for your brand and size tire.

Anything else you're just guessing. Most people can guess okay enough to get by.

GMC door sticker on my dually says 70psi front, 65psi rears.....when loaded for big trip I am just over my GVWR.....I run 70psi front, 72psi rears.....tires run good temps at speed and corner really good. I have had an issue with two OEM valve stems rubber blowing out like it was rotten....GM replaced all 7 with solid metal screw in stems under warranty, but insisted there was no problem or recall on OEM ones....hmmmm?

To the OP, I would use the door sticker ratings. For my SRW it is 75 psi front and 80 rear, for a DRW it would normally be the same in the front and 65 psi rear. DRW trucks have more tire capacity in the rear than the rest of the truck could ever handle, 65 psi will be plenty.

that is the psi what I run in my older 3500 DRW. This truck runs full axle/tire loads with my heavier GN trailers.
