Tire Talk...
Since I am running right up against my GVWR on the truck I have decided to upgrade to 10 ply tires. My choices at this point are Cooper ST Maxx and AT3 and the Nokian Rotiiva AT. I am looking for size...

Your OEM wheels are fine for 80 psi .
The weight rating for the wheel is more important .
When aluminum wheels fail they do not do so catastrophically .
Instead they develop a hairline crack at a weak point , often a ridge , and they just fail to hold air pressure .
You would be best served by going to the tire rack website and doing some research .
Plug in your tire size and research the data available in that size for P rated , load range C , and load range E .
You can choose your preferences from the left hand column to sort for price , or speed rating , or load range .
Write down the specs of the tires you are considering .
Pay attention to the tire weight between load ranges within a brand .
You will observe that an E tire weighs more than a C tire weighs more than a P tire . Dimensions are often the same .
More cords equals more tire weight .
If you like you can compare tire weight between brands as well .
I have about 60,000 on my LT265/75R16 load range E Michelin LTX highway tread .
They have suffered zero mishaps and are not quite to the wear bars .
They have not needed to be rebalanced over their lifetime .
I mostly run them at 50 psi on my duramax ( 9200# gvw ) .
I have a compressor and on occasion I have run them up to 80 psi for loads that run me up to 9000# gvw .
My duramax is typically 6800 # most days .
As you know we can weigh for free at the ODOT scales when they are closed .
