Tire pressure monitoring system (TPMS)?

[dutch6]

My '08 3500 SLT has rubber valve stems. Since these stems make it hard to check/inflate the tires (especially the inside duals) I want to change them to hard stems. Called the local tire shop and was told that since mine is an '08 it has a TPMS and the rubber stems can't be exchanged for steel. Then he said he could put extensions on the rubber stems. I don't think I like the sound of that idea, so--

Questions:

How do I tell if I have a TPMS?

Is it true that I can't change to steel stems?

Recommendations?

I don't know about TPMS, but I don't have any difficulty checking and inflating my dual wheels, even the inside tires. I have a long stem double headed trucker's gauge and a long stem double headed air chuck. I use the out side head to check and/or inflate the inner tires and the inside head to check and/or inflate the outer tires. Sounds like a bunch of double talk!

My 05 Jeep and 08 5500 have the TPMS and we were told that the sensor is on the inside of the wheel, not in the stem on Chrysler vehicles. If that's the case, you should have no problem in changing the stems to suit your needs... .

Just looking at the stems, they appear to be standard stems...

Are you 100% sure your Jeep has TPMS? My wife's 2005 Jeep Liberty Limited 4x4 CRD has TPMS and the sensor is the valve stem... ... even in the full size spare. Her CRD has the standard system; if a tire is low, the indicator on the dash lights up. The "enhanced" TPMS that was offered in some CRD's actually show the exact psi of each tire in the EVIC (overhead console).

Let me stand corrected if I'm wrong... both the jeep and the truck show a low tire... . it doesn't display the actual pressure... I had problems with the jeep about 100 miles into ownership and the dealer had to upgrade the software... . so I know it says ""low LF tire"" as an example...

The 08 5500 came with the feature but I've never personally read the manual just saw the system on the invoice and just assumed it functioned as the jeep showing a low tire...

In both cases, the stem looks the same as an old design stem... I changed more tires than I can count years ago... and changed my share of stems... . and this stem is not larger on the outside of the wheel than a regular stem... .

Last point... I just assumed there was only one style of system... either the pressure is good or bad, based on how they are calibrated... I'm not aware that one system shows just low and high and the other system shows pressure... . and that all TPMS on Chrysler manufactured vehicles were the same... .

Hope this helps. .

Not sure if this matters, but My 07 Nitro has the TPMS. It shows the tire pressure for each tire on a little picture so you can see the pressure at each of the four corners. My spare (full size) does not have a sensor. I found that out when I started using the spare and the flat tire kept transmitting date from inside the back hatch of the car. <?xml:namespace prefix = v ns = "urn:schemas-microsoft-com:vml" /><v:shape id=_x0000_i1025 style="WIDTH: 17. 25pt; HEIGHT: 11. 25pt" o:bullet="t" type="#_x0000_t75"><v:imagedata o:title="cookoo[1]" src="file:///C:\DOCUME~1\cskal\LOCALS~1\Temp\msohtml1\01\clip_image001.gif"></v:imagedata><?xml:namespace prefix = o ns = "urn:schemas-microsoft-com#ad
</o:lock></v:shape>

Either way, I have solid valve stems all around.

Partially deflate one tire on purpose, and see if the truck complains.

Is it true that I can't change to steel stems?

It might. I'm not familiar with the sensor package that Dodge used, but it's possible that the sensor is integral with the valve stem. If so, you'd actually have to remove the sensor to change to a standard metal stem. But then the TPMS would be complaining at you constantly.

The valve stem is part of the sensor. There is no way I am aware of to change the stem to a metal one. If you damage the stem and cause a leak, you have to replace the sensor#@$%!

What happens over time when the rubber stem goes bad? How expensive are these "special" valve stems?

So far I have not found a sensor with deteriated rubber causing a leak. The only leaks I have seen was from owner damage. I am retired from the dealership now and do not remember the pricing of the sensors. I would guess they are in the $50 range. Maybe someone could chime in with current pricing.

Just to further confuse the issue, I called my local Dodge dealer service dept today and asked how to identify TPMS. He said if the stems are rubber I don't have TPMS.

... which means that you don't have TPMS since your valve stems are rubber.

 

[gsbrockman]

To further confuse you guys, and I know this is a Dodge thread, some GM cars use a special rubber valve stem that attaches to the sensor inside the wheel via a short screw.



The one in my wife's Jeep Liberty Limited CRD looks almost exactly like this, and is pretty plain to note it's TPMS equipped :

Leave it to the Nazi's at GM to utilize this style for the ultimate confusion :
