TST, TPMS with internal sensors

JMO, but the benefits of an internal system don't outweigh the hassles. In fact, TBH, I don't really know what the benefits would be, maybe the fact you wouldn't need metal stems?

and not every tire shop can deal with them. We have had the Pressure Pro for years and they work just fine.

I have had my TST 507 system for 10 years. I have had to replace 2 wheel sensors, out of 8, in that time that failed and I did spring for the newer color monitor a couple of years ago. Other than that the system has been rock solid and sensor batteries and o-rings are not hard to replace when needed.

The advantage for an internal sensor would be more accurate temperature readings.

And being more accurate is important because...

Go with the 507 system and get metal stems and be done with it.
That's what I did about 10 years ago.

Having played with three types of external TPMS sensors on my Sprinter RV (6 wheels), I have a different opinion. The external sensors are much easier to install, but they can be a hassle when adding air and even with metal stems can create problems with leakage and sometimes broken stems. I finally gave up on TPMS but if I wanted to get back into it I'd opt for the internal sensors. I've had factory installed internal sensors on three different vehicles now and the only issue I've had is having to replace them when the batteries finally expired.

Now admittedly installing (and maintaining) internal sensors is more difficult than externals, but typically once they're installed they should last about 5 years before needing battery maintenance.

I can see your point, but after 8 years with external sensors, with no leaks, no broken stems, no sensors replaced, easy battery changes, and no issues, I still see no advantages to internal sensors.

I have to replace the batteries at least annually on my 12 sensors. Easy to do when they are external.
