Based on the picture, the TPMS sensor is mounted on a "rubber" valve stem. It needs to be mounted on a metal stem to get accurate temperature measurements.
The rubber stem is a thermal insulator.

Those walk around pay off. Very happy that you caught it instead of on the road. That could of been a real disaster.

Ahhh. That explanation works for me. Now I can sleep. [emoji106]

As has been said, good catch at your fuel stop, and so fortunate to have quick and easy access for the repair.

Wow, good catch. My wife gets a little annoyed waiting at every stop for me to do a full walk around of coach, toad and towbar. Definitely not going to change my procedures now.

If I’m not mistaken, it reads air temp, not valve stem temp. In fact, a metallic valve stem might show a lower temp reading than rubber as it will act as a radiator.

$1400 later....I’m back on the road!
New rear axle, four new hubs, four new sets brakes,a new leaf spring (one leaf was broken) and an extra hub and set of bearings as backup......
Great folks had me in and out in under 5 hours.......

Remember, that the sensors are simply spinning in ambient air while underway, and that's about all they will reflect, temp-wise.
I have no quarrel with those who expect more, I just don't see much value in TPMS temperature readings.

It's not reading ambient air temperature. When you put the 507 on the shredder valve it opens the plunger on the valve which allows air from the tire to move into the sensor. Without that air from the tire pushing on the sensor it wouldn't know how much pressure existed. At the same time, it reads the temperature of that same tire air, not the outside air.

I'm glad you caught that in time, it could have been a lot worse. Did you buy those lottery tickets yet? Question - there looks like a wedge of some sort between the valve stem and the rim...... never seen one before, but I like the idea. Where did you get that/them?

Blown wheel bearing. But as luck would have it, less than a mile away is a trailer fabrication business and they have a replacement axle, bearings, hub. Will be fixed first thing tomorrow am.
Always an adventure!

THANK GOODNESS you found it when you did!
My only question, how long since you last serviced the wheel bearings prior to that catastrophic failure?

Yeah, like they said go buy a lottery ticket!
I'm amazed the wheel stayed on.
You were probably just moments away from the wheel leaving the axle.
Scary stuff!

The intent is to measure the air temperature of the wheel and tire combination, which tracks the wheel and tire temperature. This is one of the reasons the sensor manufacturer recommends the use of metal valve stems. The temperature measuring element which is part of the pressure sensor chip has to have a low thermal impedance connection to the wheel in close proximity to the tire bead. There is no air or thermal circulation in the valve stem.

The hits just keep on coming! Today, outside Winslow AZ, I lost the rear universal joint on the truck! You can’t make this stuff up. Found a garage that could do it immediately and would let me help. I like doing my own work on the truck. Parts store next door to the garage. Had it replaced in under an hour. Ugh!
To answer the other question. Trailer bearings were serviced in January, before I legt for the trip. Bearings failed because brakes failed, heated grease, boiled it out of the bearings....bearings witjout grease is a bad thing.....I see a disc brake conversion in my future.

On 3/2/2018 he posted that he "Buried Both Axles in Sand" at a BLM area and stated he was glad he had 4x4 drive!  You ask if he is Rough on equipment!   Youroo!!

Before I start, I have amazing good luck with vehicles. Other than a BMW 550i that we bought a couple years ago, I simply don't have car troubles. This truck has 200,000 trouble free miles....Until this week (well, one issue was trailer, not truck)
So, here goes.....I Spent last night at a rest stop on RT40 outside Albuquerque. Beautiful night. Got up before dawn to beat the traffic, made breakfast and headed out. Wasn't a 1/2 mile down the road when I hit a shredded trailer truck tire. Somehow, a piece flew up into the engine bay and damaged the radiator fan and ripped all the wires from its electrically controlled clutch. Sheared off a couple blades! Looks like it didn't damage the radiator. Trying to drive it, the vibration is intense.
I'm on the side of the highway waiting for a tow from AAA as I need to go to a Dodge dealership which is 100 miles away....Too far to limp there.
You can't make this up.......Amazing luck I'm having this week!

A friend of mine calls that 'being snake bit' Sorry for your bad luck. If this is event number three, maybe you're done.
