Unless he has LT-Metric tires his stock P-Metrics don't gain any weight carrying ability beyond 35psi. Anything beyond that is only required to achieve the max speed rating.

However the tires max load capacity far exceeds the trucks GVWR. He should be fine but they are just going to be squishy no matter what.

I've put a ton of coal in the bed of my '13 a few times. It sat pretty much level. It was a bit squirrelly to drive. Almost like driving a stick of butter. Won't be doing that this winter.

Sorry. I appreciate help. I had really figured that this would be a simpler question than it has been. It would seem like a simple note in the owners manual would be a standard item.
Your idea is a good one. I found that a cubic yard of cement sand weighs about one ton.

Really? You don't want to use math to figure out what your truck can hold? Maybe it should just tell you, like a big red light goes off?

There are three types of people in the world. Those who are good at math and those who aren't. I am the later.

I don't mind doing the math to figure it out once, but out on the Mesa loading with a shovel, it would be more convenient to be able to tell visually.

Once you are hitting the bump stops, I'd say you have loaded enough dirt into it.

That's probably to much honestly but just use common sense and be safe while hauling.

So if 720lb will level a stock truck, Load it a little more and you should be there.
I understand the impracticality of trying to make your mound of dirt in the bed level so you can measure its depth. So maybe eyeballing the angle of the truck is a little better.
But if you want a guide, if your truck has a 6.5ft bed and we neglect the area in front and behind the wheel wells, that's 4 ft X 6.5 ft = 26 sq ft. One foot deep is 26 cuft.
A cubic yard is 3 ft X 3 ft X 3 ft = 27 cuft. So if you fill it to an average of one ft deep you'll have about a ton.
