Hmm, a company that doesn't make the stem sensors claims the stem sensors are unreliable. Who'd a thunk.

What, electronics are never wrong? ๐ I double check every once in a while, just to reassure myself.

Do we know that the stem mounted TPMS doesn't track in a timely fashion, or are we just going by speculation? It would be interesting to see the difference between the two types on the same tire. I would be willing to bet the difference would be much less than one would think.
Truckers are not going to use valve stem TPMS probably because the adding/checking air takes more hassle with a stem mounted TPMS. A stem mounted TPMS adds extra steps. A wheel mounted TPMS is pretty much set it and forget it.

Uh, the stem temperature will be the same temperature as the wheel since it is attached to the wheel, and it's a metal stem, so why should it be a different temperature?
It may lag a little behind, but basically it will be the same temperature as the wheel, ergo the stem and sensor will be the same temperature as the sensor inside the wheel. The inside sensor won't be exposed to the air moving around the wheel, but since "metal is a better conductor of heat than air" that shouldn't affect the temperature of the stem/sensor much.

Sorry I offended you. I was only trying to explain using physics why stem temperature is not as accurate as inside the tire monitors which shows that metal is a better conductor of heat than air to put in more simple terms without the mathematics.

Your excerpt:
If you think your valve monitor would have provided the same warning then show me the physics and if you are mathematician show me the surface integral of heat dispappation:
to me means I have to prove something to you. I don't. I know my system alerted me in time to save much more damage. What you feel about me, my education and knowledge of physics is just your way of puffing out your chest. So puff away. As I said, I don't have to prove/show anything to you. You are entitled to your opinion as I am in mine.To me, that is all that matters.
Our alarm went off as we were leaving the road to turn into a Verizon store. We did not have to be stopped for the high temperature to show up & the alarm to sound.
When I replied to you, I never said you were wrong. A courtesy extended to you but not returned. I said: This was not the case for us. You, one the other hand apparently believe everyone but you is wrong. Dijustme wrote:
I trust my in-tire sensor because it is mounted to the rim inside the tire and therefore will sense the change in temperature much faster than a valve stem sensor. It is the change in temperature vs time that IMHO is important. I suppose the valve sensor will eventually see the temperature change, but will it be show it in time for you to take action before permanent damage occurs to the axle? I saved my axle because I seen a small abnormal temperature rise of 5 degrees and I simply don't see how a valve stem temperature monitor would have detected that small increase in short period of time. After stopping to see what caused the temperature increase, I measured the hub with my IR gun and showed 180 deg while the temp monitor showed 135 vs a normal 130 the temperature monitor eventually went to 170 deg after stopping.
If you think your valve monitor would have provided the same warning then show me the physics and if you are mathematician show me the surface integral of heat dispappation ๐
This might help understand temperature and rate of distribution..https://www.khanacademy.org/math/multivariable-calculus/surface-integrals/surface_integrals/v/introduction-to-the-surface-integral
It is not my way or no way, but physics.

I wish I could find the pictures of our experience. Long story short, four years ago this coming April, traveling north out of Los Vegas on 15. TST TPMS system alarm goes off. Pull over, find a burnt bearing. Call Coach-Net, all taking care of, had four days left on my warranty, no cost to me. Thank the good Lord!!!
About two months later read on the internet about individual with same RV and truck as I have who also burns a bearing on his RV. He does not have a TPMS system. RV goes up in flames but he was able to pull over and disconnect the truck.
Moral of the story, get a TPMS system if you don't have one. Stop arguing about "Mine Is Better Than Yours", It's kind of childless and will never solve anything. Again, if you don't have a system get one.
