My truck came with P tires so it doesn't have the HD Payload package. The front axle is rated at 3800# and the rear is rated at 4000#.

I found a chart from Toyo tire here

but I haven't seen one from Michelin. Does anybody have a link to that one?

Yep. This trailer wheel, for example:, available from SouthWestWheel:


167041-12



Alcoa Classic Single Wheel 16" x 7" 8-6.5" bolt circle, 5.155" hub bore, 4.290" backspace inches, 0.250" offset, 3750 lbs. max load, 110 psi max inflation, weights 19 lbs., stud pilot, uses TR-542 valve stem. Comes with eight 1/2"-20 lug nuts, eight Alcoa lug nut covers, and one closed Alcoa center cap.


Price: $247.95





That Alcoa above is rated for a max of 110 PSI.

Itat - My post was intended to give an idea of what an E rated (80 psi) LT tire should be inflated to. My front axle rating is 4,050 and the recommended tire pressure on the front is 55 lb. So my LT245/70R17E tires will carry 2025 lb with 55 psi air.

I checked the Toyo Tire chart that I linked to. For a P275/65R18 tire, the max. load is 2601# at 32 psi. Going to a LT tire of the same size, you need 55 psi in the tire to get the about same load capacity (2660#). So I probably should be running the LT tires at 55 psi without the trailer. I'll have to take my setup to a CAT scale but with the rear axle rated at only 4000#, even the 55 psi should be sufficient.

So at the end of the day, as long as my wheels are OK for the weight they're actually carrying (measured at the scales) and 55 psi (preferably 65 psi for a safety factor), then I'm golden.

Yes they do. Its stamped into the bowl of the wheel inboard of the center. That being said, I don't think I've ever seen a wheel that wasn't rated for at least 80 psi.
