More LT vs ST. I know, ad nauseum...comments invited anyway...
Went to seven (7) tire places (5 tire dealers, 2 RV). All tell me I need ST primarily because the sidewalls are thicker/stiffer. 4 of the 5 tire dealers showed me LT & ST side-by-side and it seems they may be right, the ST are much stiffer than the LT (including Michelin). In fact, the LT sidewalls were so flexible makes me wonder if they're really suitable for 1T & heavier pickups. The ST felt heavier, too.

They are correct. Want a good tire? look at Greenball Towmaster Radial Special Trailer Tire. I got four for $500 balanced and installed two years ago.

Agree with donn0128. You often hear about OEM ST tire blow outs. But much lesser so about an LT tire blowout. And some manufacturers are putting LTs on their trailers.
Don't know that you can go really wrong with either. But it is LTs (Michelin) for me.

Choose what you want. If you have/had read the threads over the past six months there would be no question in your mind. There are some on here who insist ST tires are the way to go. The same ones have blown out somewhere around 20-25 ST tires in recent years. On the other hand those of us with LT tires are still merrily tooling along on our LT tires with no hint of problems except the occasional nail etc. I just took off my OE LT tires from my 2005 fiver. Replaced them with ????? You guessed it LT tires.

I put these on my TT and could not be happier... I went from a 28lbs ST tire to a 52lbs LT tire. Steel sidewalls, heavy duty everything... in a LT225/75R16 flavor...

Bridgestone Duravis R250


By far, the most heavy duty tire I have ever owned, on both a trailer and a truck... These are fantastic! I can now pull my TT without fear of constant blowout..

Once you get past a Maxxis 15" tire, I believe it becomes more of a quality and availability issue with the LT tires. You can buy a "good" quality 16" LT tire almost anywhere. Stuck on the side of the road it will be much harder to find a 15" Maxxis (the only ST to buy) than the LT tire. JMHO

They want to sell ST tires. LT tires are better for trailers because of the greater reserve capacity and are stronger. LT tires do blow out but not as often as ST tires.

What SIZE tire do you have?

If 15", IMHO Maxxis is the way to go. If 16" there are LOTS of choices.

The following quote can be found in the RMA document (chapter 4, page #49) in the reference listed below.

“Tires specifically designed for travel trailer use in highway service have an "ST" (Special Trailer) molded on the tire sidewall (ST225/75R15 or ST235/80R16). ST tires have different load capacity characteristics. Therefore, ST tires should not be
replaced with any other type tire.”
