Anyone think those are a money saving devices? I just learned that
the sensors in tires should be replaced every time you buy tires and
they are over 40 bucks per tire.

The cost would seem to outweigh any savings from preventing any
improper tire wear.

"Money saving?" for a passenger vehicle? No, not really unless one paid
no attention otherwise it's possible. They are a safety feature that is
worthwhile imo; again if paid attention to when indicate low pressure.
For commercial I think there's no question of "yes" than can easily be
cost effective...

Where did you hear they need to be replaced every tire change? I've
vehicles well over 10 yo with them and have never replaced a single one
and they still check out w/ a gauge.

The firmware has to be reset for a reference point after one has been
off the rim but that's just mashing a couple of buttons on the control
panel--just how depends on the vehicle, of course.

Snipped and hit send by mistake above......this is what I have to
do....and it's a PITA.

There are two different ways to relearn your Tire Pressure Monitoring
System (TPMS). One is with a TPMS scan tool (this is the preferred
method) and the other is the manual method (pain in the "you-know
what", but requires no special tools or equipment).

To use the manual method, set the parking brake. Enter into TPMS
RELEARN using the Driver Information Center (DIC) controls. (SEE
Owner's Manual)

When you have successfully entered TPMS RELEARN, the horn will chirp
and the left front turn signal will illuminate. Increase or decrease
the tire inflation pressure on the left front tire for 8 to 10
seconds. The horn will "chirp", indicating that the left front tire
pressure sensor has been relearned and the turn signal at the right
front will illuminate. Repeat the process for the right front tire.
The horn will chirp and the right rear turn signal will illuminate
indicating that the right front tire has been relearned and now you
must now repeat the process at the right rear tire. Then you will have
to repeat this a fourth time at the left rear. When the left rear tire
has been relearned, the horn will sound a "double chirp" indicating
that the relearn process has successfully completed.

Yep, that's how I did it! I had to read it a couple of times before I
believed it! LOL

And you need two people to do it.
