The Tire loading chart also specifies a set PSI that the payload of the truck is set at. Most half tons payload is calculated around 36psi on the door sticker.
This is the problem I have with the silly payload sticker. Once you change the variables (modify) then the capability changes. No the payload sticker doesn't change but who really tows a TT at 36 PSI? I'm airing the tires up to the Max PSI on a half ton.
What if I put P XL tires on my half ton with a max PSI of 51 psi and a max tire load of over 2300 lbs each? What if I fill my tires to 51 PSI...the tire is fully capable of carrying the stated weight at the stated PSI on the tire sidewall.
Now we get into the operators ability to know the equipment and operate sensibly.
Reminds me of a loaded Ram 2500 4x4 Mega Cab I looked at recently...awesome truck...but had less than 2,000 lbs payload. I think it was actually less than 1,800 lbs.
I pointed this horrible payload rating out here on a thread and someone made the truthful comment..."put 1700 lbs in the bed of that MegaCab and it won't hardly even squat."
TIFWIW...use your noggin and operate sensibly...I don't care if it's a half ton or a HD truck...load and operate sensibly. If you don't know how...learn how to load a truck and trailer..don't just stare at a computer and read ratings numbers. Go rent a small UHAUL trailer and lead how loading impacts handling...spend time pulling that little trailer and learn how to properly load.
Clueless Newb with a huge trailer under all ratings with zero experience In a truck, loading a truck and trailer, and COMFORTED by the fact that they are under all ratings is more of a danger than the experience operator running a little over that silly sticker on the door.
