tire pressure monitor systems

I couldn't find much with a thread search but was wondering about how the systems that go inside the wheel compare to the valve stem cap type. And would also like to hear everybody's experience with these systems.

Not sure what you searched for but if you used "TPMS" lots of threads come up. Here is one you might find useful.

I have access to a fleet of vehicles to drive for the work I do. Most of these are equipped with the in wheel type pressure monitor systems. In the past two years no fewer than 6 of the vehicles have had a sensor failure in one wheel. This requires the dismount of the tire and replacement of the sensor. I seem to remember the invoice for one of the replacements was $280 parts and labor...but my memory isn't what it used to be. I know it was more than $100 because the fleet maintenance carrier had to be called to appprove the work.

For me I would go with the valve stem cap type external sensors just for the ease of replacement.

I considered the internal kit but the downside is if you have a problem, you have to dismount the wheel. I went with the external TST 507 system and it's been working fine for 3 years.

I have Pressure Pro (external) TPMS for the motor home and the toad. The toad was also factory equipped with internal TPMS for times its not being a toad. Both units have worked flawlessly. I wish there were some way of monitoring my Toad's internal TPMS on my Pressure Pro monitor when I'm towing it. Alas, ain't gonna happen.

My 2012 Ram has those and so far they have not been a problem. I can take'em or leave'em. I did have a huge bolt go through on of my tires and it told me which one, but it also didn't take long to figure out which one of them went flat either. It kind'a pulled to one side. It is fun to play with and watch the pressure change during the day, but that's about it. There has been no problem when I go to change tires either.

I used to have one on my MH (before stem type came out) and it worked great. The company who I can't think of the name pulled out of the RV market. I had problems with getting the tire changed on my tow rig as the people didn't know how to do it. MH tires no problem.
Think they are only good for 18 wheelers as they change tires regular and replacement of batteries can be done on regular maintenance.
With the stem type available I guess that why they pulled out of the market.
The cost was like 2-3 times the stem type.
