Question about tires
I have been learning a lot about tongue weight and payload capacity lately, but I have not even looked into tire capacity and weight rating at all. I am going to need some help with this. So my truck ...

Jim, not to discredit the tire boys, but the manufacturer of the OP's tires says they are LT tires, which I suspect is true with a max psi of 51 and 2,535 LR. .....
Sorry, but here's another correction:
1) P type Standard Load tires will have a max pressure of either 35 psi, 2.5 bar (36 psi), 44 psi, or 51 psi. A P type XL (Extra Load) tire will have a max pressure of either 41 psi or 50 psi.
2) An LT tire will have a max pressure of 50 psi (Load Range C), 65 psi (Load Range D), 80 psi (LR E). etc. (with some exceptions)
3) It is common for tire manufacturers to put letters in the model name of the tire including LT, ST, HT, etc. This does NOT mean the tire is an Special Trailer, Light Truck, or Heavy Truck, etc. type tire. Those designation are in the SIZE - and in the case of ST and LT tires, they are explicit. (others, like P type, they are implicit.)
You may find some exceptions to the above as not everyone has a good understanding of how this works. For example, there are several tire manufacturers who put on the sidewall of their Standard Load P type tires: Max Load XXXX pounds @ max pressure 44 psi. This is sort of incorrect as the max load occurs at 35 psi, but 44 psi is the permissible max pressure with no increase in load.
Yes, I know it is confusing.
