There are several threads on tires for various trailers on many RV forums. You might want to do a search and read what others have said. There are many strong opinions on tires.
I chose an upgrade on my trailer to Maxxis tires but Goodyear Marathon tires are also well regarded by some. ST tires are designed for trailers. Many claim success with LT tires while others say the sidewalls are too pliable, the tread is too soft and they can cause towing problems. I have no experience with LT tires on a trailer. I recommend you keep up your research as opinions are not necessarily facts.
