It appears to me there is a valve stem base screwed into the rim and then the actual valve stem screws into that base. It looks like I could put a socket or wrench on the base and unscrew if from the wheel but isn't there a pressure sensor on the other side? I have tried to extract the inner valve stem but have been unable to do that. It appears I would only need to replace that inner stem. Is that an item I can get at the local tire shop or auto parts store (it does not look like a standard valve stem to me)? Do I need to remove the wheel from the car?

On a related subject, is it a bad idea to leave the car stationary (parked) on the runflat for a few days with no air or should I jack it up or keep moving it to a different spot? If it needs to be jacked up how should I place a jack under it?

Thanks for any suggestions.

The valve stem is part of the tire pressure sensor.

Do some research here on this forum regarding valve stems/tire pressure sensors.

When you dismount a Prowler tire I think the proper procedure is to let all the air out, remove the nut and allow the valve stem to fall inside the tire. This should prevent damage to the sensor when dis-mounting the tire.

If I am incorrect, someone will respond here with their interpretation on what to or not to do.

As far as the jack is concerned. I would suggest that you put it on the lift pad on the frame and only lift enough to get the tire off the ground. I would also suggest a rag or small piece of wood between the jack and the car if you are worried about scratching the frame.

Do NOT lift the car by the lower control arm or try to lift under the center front part of the car. JMO

I hope this helps.

That is what you need to take out the core. Any gas station or tire shop should give you one free.

Leave the tire on the car and don't worry about harming the tire. Remove the old one and replace it and fill it with air.
If you have an old bicycle or a wheelbarrow with an inflatible tire you can actually take the stem out of one of those to use. They are all the same.

At this point I will try and obtain a new sensor and drive the car to the closest tire center which is about 6 miles.

Unfortunately I believe the company that transported the car ran their tie down strap through the wheel and broke the valve stem/sensor assembly when they tightened the strap. There was a 2" wide mark through the wheel right at the location of the valve stem. Fortunately there does not appear to be any damage to the wheel.

Thanks,

I had my TPMS's installed at Goodyear since my dealer did not have a runflat friendly tire machine. Some tire stores can "sync" the new TPMS to the on board computer; but your dealer can definitely can do it.

You may want to think about replacing all four since they only last about 5 years. Most likely the dealer is going to charge you $100 to sync one sensor; probably the same price for all 4 sensors. Also a good time to swap the tires side to side since the tires will be off the rim.

Thanks for the tip. I don't know if mine have ever been replaced.

To swap sides you would need to make sure that the directional arrows are oriented properly.

Bad news is the 1997-2001 are proprietary to Mopar (not sold externally). Besides the 1997-2001 TPS has been sitting on the shelf for 9 years.

The good news for 2002model TPS is only $52 and there is plenty in stock.

Here is a 1997-2001 TPM sensor:

Here is the 2002 TPM sensor:

when your TPMS batteries start to go in your 1997-2001; it is cheaper to upgrade the whole system to the 2002 model:

4 x $53 (New TPS) + $115 (TPMS module) + $100 (dealer computer) = $427

4 x $224 (Old TPS) + $100 (dealer install) = $996

Therefore, converting to the "new" TPMS system saves a 1997-2001 Prowler owners at least $569 if not more!!
