I don't know that I would pay strict attention to what the placard states, and OEM fitment of tires. I would go by what weight is actually on the tires/axles.
The builders actually de-rate the axles so the cheapo tires they put on will be a match to the axle ratings. The axles on my Fuzion are 7,000 lbs. rated, but they were de-rated to 6,800 lbs., so the builder could put the cheap Carlisle ST tires on that are rated at 3,400 lbs. If the axles were rated as they should have been, i.e. 7,000 lbs. the Carlisle ST tires would not have been rated high enough to be used. Just more weaseling by the builders.
When my Carlisle tires blew after less than 8,000 miles, I seriously considered going to an LT "E" rated tire, because I wasn't about to pay over $300/tire for the Goodyear G614. I have weighed my individual wheels and know that my highest weight was 2,500 lbs. With LT "E" tires rated to 3,042 lbs. I knew I was easily within the carrying capacity.
However I discovered the Sailun S637 and went that route instead. So far so good.
Tire selections fitted to your RV trailer axles are done in accordance with Federal Motor Vehicle Safety Standards, which includes recommended cold tire inflation pressures. Tires selected and fitted in accordance with the Federal Motor Carrier Safety Administration's standards are fitted to the weight carried and have no cold recommended inflation pressures.
Here is a new reference that clearly describes a tire industry standard for replacement tires to provide a load capacity equal to or greater than what the OE tires provided.
