Every tire manufacture and trailer manufacture will tell you not to, never to, use a tire with a lower weight carrying capacity than what came equipped on the trailer or as placquered on the vehicle…
In other words a tire rated for 2540 pounds needs to be replaced with a tire that has a rating of 2540 pounds or better… it could be a ST, LT, or a P rated tire that has been derated, this is only the starting point…
2470 pounds falls short of that by (70) 280 pounds but if upgrading to a LR E it falls short by (360) 1440 pounds… based on the G 26 load rating they may be a good option for the ST 225x75Rx15 in LR C…
Truth be known few trailers have designated anything but a ST tire for use on their units, and if you think it doesn’t matter, it is the reason no tire manufacture will recommend a LT or a Commercial tire for a direct replacement for a ST tire… it is the reason many tire dealers will not knowingly replace a ST with a LT…
Hopefully if you do it on your own that their use is not considered a misapplication and misuse of the tire if it fails, and it will be if wording in the warranty don’t support it... read below…

From a RV net member…
“Called BFG and had a recorded conversation with Alvin. He immediately asked me the year of my vehicle and when I said 5th wheel he quickly began to lecture me on the BFG not being a ST tire and that I had misapplied the tire by mounting on my 5th wheel. He explained all the advantages of ST tires on trailers and yes he was aware of the horror stories of damages they cause. I had told him that I had removed them from a previous 5th wheel because I refused to have a trailer with ST tires. He got part of that story wrong when he repeated it because he said I took them off a truck. After I corrected him he said by taking a tire off the original vehicle and putting them on another I automatically voided the warranty. “
“He then began to tell me that the ST tire-and he said BFG doesn't make them-are rated with a higher capacity that LT tires. DUH!!!I told him that I was aware of that and my axles are 5200 # and I have weigh tickets and that the BFG tires were well within the limits of their capacity. He then began another explanation of the legal ramifications of having LT tires on trailers and that from a legal standpoint BFG was declining any assistance of the failed tire. “
“To sum things up:
I voided warranty of the tires when I put them on a trailer.
I voided warranty of the tires when I moved them from one vehicle to another.
BFG from a legal standpoint will not honor any warranty for LT tires on anything other than the original installation of a light duty truck.”
Snip:
While many of the illustrious car guys and self- proclaimed experts will tell you this is no problem and to trust them on all things tires, let them point out the warranty language from any manufacture that includes the wording to substantiate their claim of trailer use…
So many assumptions made through so many apples to oranges comparisons, equals logic to their superior minds…
It so hard for this commoner and lowly civilian to take their words and recommendations seriously when so little if any of their self drawn conclusions drawn from unrelated data be found in any of the tire manufactures material and data…
That’s way they want you to as proof to search and read their last post… it’s the only place to find their self drawn conclusions…
