Empty, 35 psi in the 4 rear tires will give you a much better ride. Chris

Do the math. To “need” the full 80psi in rear duals, you’d need to have about 10klbs on the rear axle.
Otherwise, run whatever pressure you need for the weight.
You can run too high of pressure if you want. It will only result in a rougher ride, less traction and potentially premature tire wear (but not prevalent on skinny Dually tires)
When I used to plow snow with a dually, with only a 1000-2000lbs in the bed for traction, I’d run the rear tires at 25-30psi, similar to when driving with no weight in back.

60PSI gives the tires the load carrying capacity to carry the factory rating of the truck. It's the pressure of the air in the tire that gives them their weight-carrying ability. 80PSI on a Load Range E tire gives you its maximum capacity. Maximum capacity on the tire is not needed to reach maximum capacity on the axle, so 60PSI.

For liability reasons, the installer will not exceed the door sticker. You can do whatever you want after you've driven off their lot, but they are not going to exceed manufacturer's specifications, even if you say it's okay.

60 is plenty in the rear of a dually because you have 4 tires taking the load rather than 2. The bonus of this is that the truck rides much better with lower air pressure. I run 80 psi in the fronts, though.

Simply asking if the above tires which are the right size would be a good choice for my truck? 2013 chevy 1 ton dually 4x4. towing a 5th wheel around 12,000 lbs

Umm, sure they’re perfect.
Or, no, they’re totally wrong for your application.
Or somewhere in between.

Since we have no idea how you use your truck or what characteristics you want out of a tire, other than it’s hooked to a 5ver sometimes, we can’t say.
Do ya go muddin thru cornfields?
Use it in the snow?
Tow things in the snow?
Garage queen that only sees blue skies and sunny days?

Tires are very personal in type, tread design etc.
Not sure what version you have chosen, highway tread vs traction or AT on a 4x IMHO, does not matter. Depends on your driving style and where. If all highaw, go with an agressive rib design. A bit of off road, snow etc th an AT. If off-road in mud etc, better go traction.

I've had two sets of continental, no issues.

If your truck is 4WD, I'd get something along the lines of an AT tire.

Cooper Discoverer AT/3 is a good choice. I run that on my truck

[Grit_dog]

They’re tires, Continental is good quality afaik. Your truck won’t care.
Use them if they’re the ones you want.
(Didn’t read the link, but presuming they’re the right size and load rating, in case that was part of the rather vague question. )

Not sure what you mean with the above phrase being stated as a question.
