This is a fact you should be aware of tire/payload sticker was not required until 2006.
The payload sticker has nothing to do with tire size. That's one of the purposes of the vehicel certification label.
The abuse an LT tire takes on a TV is far worse than it takes on a trailer. That's mostly because they are on drive and steer axles and are designed for them. The only entity that has the authority to say it's an appropriate fitment on other vehicles is the vehicle manufacturer. Many blame instances of curb scuffing, potholes, and hitting bad RR crossings for blowouts on ST tires, while I try to avoid these I don’t worry when it does happen.
As to weight capacity, seeing how my LTs have a 3,042# capacity good to 106 mph, I would believe that at 65 to 70 mph they are capable of supporting more than that at the lower speeds. I don’t expect them to support any more than their rated 3,042#, in fact they are only supporting 82% of that when fully loaded with 10,000# on the two axles.

On the record, no one will officially say a LT or ST tire with a 3042# maximum load capacity really has a higher load capacity. However, there are two standards for measuring a tire's load capacity. For all ST & LT tires the Load Range formula is the official number. For all passenger tires it's the load index formula. So for the LT235/85R16 LRE tire the maximum load capacity is 3042#. If a load index number of 120 was used for that same tire it would be 3086#....It's just how the industry works.
