You would expect the pressure to drop. But, if there was also an increase in temperature, that could raise the pressure back up. If your TPMS measures pressure and temperature then you would still expect to see a warning based on one of those I would think.

Our 2014 31' Classic Michelin LT225/75R16/E LTX M/S2 tire loads are:
Classic Scale numbers May 2014
……1200……——1200
2034……2042—4076
1921…….2062—3983
Total weight——9259
We target 2,500 pound payload so that is 72.5 psi per the load table. So we set pressure at 73 to 75 psi. That is still slightly more that a 15% safety margin. We tow at a max speed of 65 mph. The trailer tires get covered when exposed to sunlight.

Because they work and are extremely reliable :-).
In three years of running LTX 15" Michelin tires on our 30' AS I only need to adjust the air pressure when we migrate to FL in the fall and back up north in the Spring. Its almost boring.
Unlike the GYM tires where I had to add air every other day for sure. Not having GYM ST tires is one less headache to deal with every day. Not to mention the anxiety of having to maintain your speed under 65 MPH.

Airstream offers Michelins as an option on new trailers. I wonder if they've had a discussion with Michelin about the suitability of their tires on travel trailers.

That is what I would have anticipated ....... but maybe not, someone said they just get them from a local tire shop.
A bit surprising if they did not do a little more checking.
So far, I'm still very happy with mine anyway!

I've been more than happy with our Michelin LTX, but I gotta tell you, they look pretty rough after 25,000 miles. Besides two obvious flat spots, the tread is mangled. It's like chunks are taken out. Had a mechanic tell me that can happen when the shocks are bad.
Answers the "why does Airstream install shocks on axle" question...

It was my understanding that Michelins were found to be good bias ply replacement tires. That would have been before STs were available. A Canadian company is blamed by some for the application, but that may be one of those unfounded legends that gets told around the campfire to keep Bigfoot entertained. Pat

They are not implying tires used on trailers, rv, and commercial vehicles are a misapplication, just that heavy duty use is not warrantied.

I've had non paved roads take chips off tread of older tires.

LTX is a passenger car tire? Check the load ratings, that is why I went to 16" Lt ,light truck tires...

Curious whether you replaced the shocks here?

It's not so obvious from the formatting here, but we're looking at footnotes, and neither applies to the warranty. Footnote 2 that "...specifically excludes trailers, recreational vehicles..." refers back to the 3 year flat tire changing assistance.

Tires, blah blah, GYM, Michelin, blah blah, we're all gonna die, blah blah. We moved from 15" wheels and GYM's to 16" wheels and Michelins. We run 68 PSI. Discount Tire sold us the wheels, tires, and a warranty on the tires. We sold the 15" wheels to a fellow streamer who's re-building an Airstream. He's happy. We're happy. Life is good.

Rocinante, this is a TIRE thread, we're talking 15 and 16 inch wheels and even more so GYM vs MICHELIN, the thread is only on post 56, you can't blah blah blah it until it goes past 200....

LTX/MS2/P235 R15/108 T is a light truck tire as in Pick Up.
I have the same tires in 20" on my truck.
And yes at 50 PSI it has a D rating and is a perfect replacement for the GYM with the 15" wheels. I did my research before making the change and could not justify the additional cost to go to 16" wheels and tires.
I have been tooling in around with these tires for 3 years, on interstates usually moving at 70 to 72 mph depending on conditions and they have performed flawlessly in every aspect.

These are not LTs, as designated by the "p". They are passenger tires.

We need to be careful about statements like this. I will agree that the number of GYM failures is much greater that Michelins people have put on their trailers. If indeed the "failure rate is common" I would like to hear the background for this comment. I would guess that there are many many more GYMs on trailers out there than there are Michelins. It is very similar to those who trash Ford pickups because you can read about a lot of problems with these trucks. The big issue is that with a very large number of them on the road you will naturally hear about more issues. Doesn't mean they are bad trucks, just that there are a lot of them.
Another factor is how people take care of their tires. You can hear many who have had no problems with their GYMs and I would hazard to guess that is because they are the type who pay close attention to things.
If you like your Michelins, or Maxxis, or Towmasters, I hope you enjoy them. Just please don't tell me that mine are junk, and that I am putting my family at risk by using them. So far this thread hasn't gone there and I do appreciate that.
