My EB has rubber stems and 80# max tire pressure on the Michelins,

And I thought I was done when I swapped out the bimetal lugnuts, , ,
No "High Pressure - Snap in" are not news. I even mentioned in previous post. While they can handle the higher pressure I am unsure about their ability to have no flex when a TPM sensor or hose extender is used on them.

You can still file a complaint. Simply identify the Discount tire store as the seller and let them worry about establishing if the valve or their workmanship of doing the install was the cause of the failures.
I would enter under Tire Complaint.

BTW, I had the stems, referenced in post #25, installed yesterday. They fit fine in the Sendel wheels and are the perfect length for the sensor mounting.

The sensors with the Dill system go to sleep when not moving extending the battery life.They wake up at 20-30 mph

I just recently installed the TST TPMS system with external sensors at the same time as I replaced my bearings and installed centramatics.

Although I have not had them for long I am very pleased with the setup. I have noticed my right tire runs about 6 degrees hotter than the left one, but both are well within temperature range. I am not too concerned about the rubber stems, the sensors are very lightweight and in talking to TST they should not pose a problem. One of the things I really like about the TST sensors is that they require a key to remove, have user replaceable batteries and when not threaded to the valve stems they go off conserving their battery.

My only complaint is that the little LCD panel that reports tire pressure and temperature is made to monitor something like 22 wheels and I only have 2. But the panel is small, attractive and comes with two different mounting systems.

I have no personal experience, but there have been some fans on the forum in the past. I bet if you search on Hawkshead, you'll find quite a bit.

I wouldn't be too concerned with a 6 degree difference in temperature as we do not know if 1. Your loads are different side to side or 2. If the TPM sensors are exactly identical.
I have done a number of comparison tests and posted the numbers on my blog if you are interested.
If you are really concerned then I suggest simply swap the sensors. You don't even have to re-set the TPMS system while doing the test. Now is the "Hot tire" still hot or did the increase in temperature move when you moving the sensors?
Just remember to either move the sensors back to their original position or do the system reset so you are getting the correct reading from the correct position.

If the Hot tire is still the hot tire after the sensor swap then I suggest you need to learn the actual loading on each side of the axles as higher temperature could be indicating higher load so you may not be setting the tires to the proper inflation.

My point is, we both purchased simple TPMS systems for our trailers this year and, with every blow out, our trailers were spared damage with these monitors!

TPMS systems are the only way to go!

I found a $300 system on EBay to monitor all eight tires on truck and trailer. This system saved me THOUSANDS in trailer damage!
With that many failures something is wrong. If it isn't your load, inflation or speed then there may be problems with the tires. You really should be filing complaints with NHTSA.
Failing to file complaints is not helping yourself or fellow RV owners get better quality tires to the market. Properly filed complaints are important if NHTSA is going to consider or start an investigation.

Based on my reviews of posts on RV forums and of actual actionable complaints filed with NHTSA we are our own worst enemy when it comes to properly reporting tire failures to NHTSA as we either don't bother or if a complaint is filed incomplete or incorrect information is provided. The net result is that some questionable tires continue to enter the RV market.

You might consider the length of warranty.

One year seems to be the norm for RVs and RV products ( pretty poor in my opinion considering that many vehicle manufacturers offer 3 to 5 or 10 year warranties)

I know of at least one system with replaceable batteries and three year warranty.

Gosh! I haven't posted here for a while and need to catch up!
First question: Nature of tire failure - I don't have any pics right now but I'll post when I can take some. 60psi per AS manual on all tires. Tread separated two different ways - one bulged out the sidewall and all the others blew a bubble under the tread. At some point the bubble just split or popped and my TPMS started screaming. Each time I pulled over very quickly (envisioning the tire flying apart and causing damage) in time to hear loud hissing noises. Was it a blowout? It didn't go "bang" if that's what you mean. Each time the "bubble" had all the rubber worn off and a split in the tire where the air got out.
Next - My TPMS does consist of the round sensor hanging off the stem. I can see where it has touched the wheel a bit. My truck stems are all metal and there is no evidence of movement.
I'm in the process of changing to the 16" wheels and tires. I purchased a set of the Sendel wheels and have installed metal stem already. I'm now looking at tires but don't intend to drop $1000 on a set of the Michelins. There seem to be a several good brands out there with the exact same specs at half the price. I'm still looking.

Looking forward to seeing the pictures. Please get close (about 2' or so) in direct sun will give best results.
Not sure how the sensor touched the wheel if something didn't move. Are you sure the valve is properly tightened to the rim? There are torque specs but a lot og guys don't follow them.

??? I believe the OEM sensors may wake-up with the PCM & or ECU, as I get readings with just the key on. I can program/re-set them without using the TECHII or moving, by cycling the DRL's, letting air out 'til the horn sounds and then setting TP.

I have forgot after rotation.....makes accurate readings very cornfusing.
