I need to replace my tires on my TT. I have ST225/75D15 Duro tires. Please tell me if my memory serves me. ST tires have larger poly cords and a stronger side wall than LT tires? is this correct?

If you can get LT tires in your size or close to it make the switch. I have never seen anyone on this forum that switched to LT that had any issues. LT tires meet different (tougher)goverment standards than STs which in general are made as cheaply as possible. I have even used high quality passenger tires on a travel trailer rather than use STs. I had no issues with those either with several thousand miles on them.

I would stick with trailer tires (ST) because they're made for towing. I replaced my GY Marathon's (225/75 15" LR "C") with Denman's, same size LR "D". Your tire dealer can order them.
You'll read arguments on both sides of LT versus ST.
You choose.

I don't believe you can get LT tires in 15 inch. I do believe switching to 16 inch would be the best option if your situation allows it. For our rig, it simply wasn't a viable option. If you are staying with 15 inch rims, either Maxxis or Denman would be a prudent choice. I bought Denman Express ST Radials (made in Mexico) E rated 10 ply. I did have to by new wheels capable of the required 80 PSI. I also had metal valve stems installed.
Best of Luck!

ST tires have stiffer side walls to help as the trailer moves left and right when being towed. I would stay with ST but get radials load range E.

Yep I have Michelin LT (load range C) tires in 15 inch on our trailer.

True, but for that very reason they also run hotter, wear faster, age quicker, and normally will never see more than a 3 yr life span at best. If you go stump jumpin w/ your trailer, you may need them, but if your trailer's tires don't see any more abuse than your passenger car tires, passenger car radial tires will last longer than anything else on a trailer,....provided that the maximum load ratings are not pushed.

Yes you can! The LTX and Cross Terrain come in 15 LR C 35 PSI max. I had meant to say to the OP that I could not find a 15 LT in an E rated tire or one that would meet my rigs (and probably his) weight requirements.
Have a great weekend!

P radials in trailer use need to have load ratings DOWNgraded by 10%. I tried P-radials on trailer once and took them off at first opportunity -- Trailer waddled all over behind me -- I could even tell the difference just stepping into trailer!! Put STs on trailer, moved P-radials to rear of truck (both 15" wheels) and all was well.
