Can you actually imagine 99 mph with a 34 in tow? Crazy scary thought!

There are LT tires where the manufacturer is more than okay with their use as trailer tires. Jimnlin on Woodalls has several times compiled lists, and correspondence, of several brands and models of such.
Let's remember that ST is a recent tire designation. Not so long ago any trailer tire of this type was a light truck tire.

Even the vaunted USA & European mfgrs can make a defective tire, as the Michelin noted above.
I too had a belt separation blowout at 65 mph of a <24 months & >90% tread Michelin LT 195/70R14-C 8PR tire correctly spec'ed as OEM for our 1988 VW Westfalia camper van (back when Michelin still made them)!!!!
So, yes the LT Michi's DO FAIL as well, & don't let anyone tell you otherwise!
Is there any harm in running LT tires on a trailer? - well other than LT's having more "grip" & rolling resistance than ST tires, which are made to roll easier by design since you're pulling & don't need the traction - probably not, even if certain folks above & on here will tell you the visa versa is a disaster waiting to happen.
Far more important is that the tires are less 5 years or less old, no checking or splits in the sidewalls or treads, inflated to proper pressure, properly sized & rated for your trailer, inspected regularly ...
... & that your TV & TT tires are not overworked by speeding or running fast & hot through the desert 120+ degree heat where pavement temps can exceed 200 & that overheasts & thereby over pressurizes properly inflated tires, & any other "stupid 2-legged animal tricks"!
Now to my ST tire recco ....
On the recommendation of a vintage trailer restorer who has done 100s of vintage trailers, I'm running the MAXXIS M8008 ST225/75R15-E 8PR (we could use D 6PR on our Avion T20, but they are hard to find in the lower rating).
You cab find them at the MAXXIS link below, then check for one of their local tire stores which carry them near you - but you'll probably need to have them order them for you.

Good Luck whichever way you go!

Good Morning Tom,
Terrific info. Question: Would there be any harm moving up to a 10 ply 225/75/RS Rather than an 8 ply as recommended. I doubt if my 25' A/S will ever reach 7,000lbs.?? Max is 6,800lbs. Dr. De:

Tire choice clarification
Mannnny Thanks Jim,
Several questions: where do you note dual rating. I see only LT? Also, for my A/S which calls for 225 I do not see a tire listed as such. The closest is a 235. Any further thoughts appreciated. Dr. De

Q speed rating which is 99mph. I've not had it that fast....

If you like your ST tires by all means keep them. In short drive, cool weather conditions they may work for you.
I take at least one hot weather freeway trip a year as we drive from Mexico, through Arizona and New Mexico to Colorado in June. I have a 25 foot Safari and D rated 225 ST tires were way below their load limits. I would have at least one ST tire failure every time I took that trip. One year I had to go from Tucson, Az to Ft Lauderdale, Florida in late June. On that trip, I had 4 ST tire blowouts. One tire lasted only 200 miles. Ever wonder why there is a fly by night tire store at nearly every exit down south and there are tire hunk alligators that line the shoulders faster than the highway department can pick them up? Now I know.
Believe me lying down changing a tire on the shoulder of an interstate in 100 degree weather with semis blasting by is no fun.
I ended the trip with Maxxis E's. They lasted a while before the tread separated and never did blow out. If you have to have ST tires Maxxis' are the best. E rated tires near maximum inflation pressure will give you a bone shaking ride.
Speed was always under 65 and I checked pressure every morning. ST tires are designed for 65 mph, 100 degrees or less. On a freeway trip in hot weather you will exceed the temperature limit every day and you will have ST tire failures if you drive enough miles.

So far, the 15" ST tires are costing me a whole lot less. I've only run the 16"Michelin for 2 years or only 60000 miles..... I'm in the camp of not so happy campers!

That's a real bummer. Especially the (non) warranty. Michelin does approve the XPS RIB for trailer use.

Please provide a current reference.
On another note; Michelin dose not warranty LT tires when used as replacements for original equipment ST tires. They consider it a misapplication of the LT tire.

I have Tow Master ST on 1969 Safari since...wait for it........2006...I hear the haters coming! No issues..None. Stored inside; Always check tire pressure before, during and after each trip to the Adirondacks. Mixture of freeway speed of 65mph-75mph to US Route speeds with twisting back roads.
Drove from Ocala, Florida to Helena, Ohio to East Ryegate, Vermont in 2007 same tires no blow outs, lose rivets or internal damage. So I'm replacing my 3-2006 Tow Master ST's with 2015 Tow Masters ST225/75r/15

I’m not a Michelin slammer, I have a new set of Michelin’s on my SUV. However, their XPS rib is a very durable, retreadable commercial light truck tire and very expensive in it’s size category. Michelin does not tout it for any sort of trailer service. That would be in the decision making process of a vehicle manufacturer.

If Michelin doesn't tout them for trailer use, then why is the first review on the link you posted read in big bold letters "My Horse Trailer Tires for 13+ Years!"?
On their RV site they are listed as "All Position" tires.
I didn't say they were the best choice for an Airstream, just that they are approved for trailer use by Michelin.

Airstream now offers the Michelin LTX on trailers as an option - just saying. The two tires listed in their parts section are the Goodyear Marathons and Michelin LTX.

True.
Black Aces will tell you that LT tires on a trailer are a "mis-application".
Black Aces,
What tires do you have on your trailers? Sizes etc...???

The Vehicle manufacturer has the ultimate decision as to what they will use as tire fitments on whatever they build. Once they chose the LT tire design for trailer axles and show that choice on the certification label that’s then the proper tire for that trailer.
Michelin considers replacing ST tires that are listed on a trailer’s certification label as OE tires a misapplication. However, they do not consider replacing an original equipment LT tire on a trailer with another LT tire to be a misapplication.

One that I don't have to shut down because the users can not comply with the TOS or CR listed at the bottom of every page and everyone agreed to when they signed up.
And I am not asking for agreement on any issue by any parties. What I am asking for is being civil, state your point of view and in the face of opposition to agree the other party has the right to disagree with your point of view. Then move on. Trading posts and restating points of view isn't productive for the posters, the readers and certainly not for the volunteer mod staff.

NO I know of no tire rated above 75 for RV application by the tire manufacturer. Tires can have their capabilities changed based on application.
If you put a P type on truck or trailer you need to de-rate the load by dividing by 1.1
No matter what the speed symbol is when in RV application (trailer of MH) the Max speed rating is 75 (until someone can show me a clearly stated exception from the manufacturer)

If by "recent" you mean 1980's you are correct. They are listed in the 1990 TRA yearbook.
