Truck tires on tt?

You can get an LT tire in a "C" rating. But that's it. I was looking for an LT tire for my current TT, nothing in a "E" rating. I ended up running Carlisle's in an "E" rating which have worked very well. I got 5+ years out of the first set, I installed new ones last year and I expect another 5+ years from them.

Truck tires and trailer tires are two different animals. The truck ones are not as strong in the sidewalls and the general method of building is different.
The main problem with having a trailer just sit is they rot out from the inside as the need to move to lube the inside.

I modified the suspension on our small fifth wheel just so I could run 16" LT tires on it. You want to stick to ST or LT tires, and LTs only come in 16" and bigger. For 14" and 15" another option is to switch to better brands of ST tires--Maxxis is popular and that is what I use for 14" and 15" trailer needs. If possible it would be a good idea to increase the rating of the ST tire that you're using by going to a higher ply rating (such as switch from C to D) or a wider tire (215 to 225). Search for threads on tires--probably one of the top 3 topics. In fact this thread will probably explode just after everyone wakes up.

14"/15"/16" light truck and passenger tires were used for many years before the tire industry gave us the infamous ST tire.

Trucks don't use 14" or 15" wheels anymore so all those sizes LT and big P tires we used are history.

We have a fair selection of 16" LT tires up 3750 lbs for using on a trailer.

I could find and make a list of LT or P tires but it would be easier if you could tell use what size/load range the OEM tires are on your trailer......or trailers axle ratings and its GVWR.

Doing a search, you will see a lot of LT vs ST tires discussions. Entertain yourself with them.

Have not done it myself. I ran into a campground host this week that suggested truck tires. Until that moment, I would have never thought of that. He was one of the hosts at Florida Caverns State Park.
