Hello All;
I have seen an upcharge of $15 to $30 per tire for dismounting a tire with sensors inside the tire. If the dismount is not done correctly the sensor is distroyed. Use a high quality tire shop and chances are the rims and sensors will survive. Also the valve extensions on the inner tires can and will cause more headaches than they are worth.

We have a factory installed TPMS system on our 2007 Honda CR-V. WE have used Discount Tires for new tires and did not incur a special handling charge. Now, having said that our situation are the time of getting new tires was quite unusual. We had broken a valve stem. The valve stem is an integral part of the TPMS and the cost to replace one stem was something in the neighborhood of $165. Discount tire was able to attach that portion of all 4 valve stems inside the rim so that we could travel down the road with standard valve stems with our Pressure Pro sensors in place. There was a one-time $40 kit cost to put the sensors inside the rims. So far all has worked very well. Both systems work independently of each other.

As many new cars today come equiped with TPMS, the tech's at tire stores should be trained in the methods needed to properly mount & dismount tires which use these systems. As this is an added procedure, I could understand if there is a small fee to provide competent service...emphasis on the competency piece, eh?

Consumer beware when purchasing anything. The pro's & con's should not become a surprise after purchase...FWIW

not just many:
After five years of continued debate, the
NHTSA developed a new ruling that states as of September 1, 2007 all 2008
model passenger vehicles, light truck and buses are obligated to have a sensor
-based tire pressure monitoring system (TPMS). The TPMS alerts drivers when
one or more tires are underinflated 25 percent below the vehicle
manufacturer's recommended inflation pressure.

Yeah, I was surprised to see an earlier poster refer to valve "extensions." These are a big no-no in my understanding. A LONG valve stem is OK. But not a two piece job ANYWHERE inner or outer.

Paul,
Why do you not like valve extensions? It is very difficult to use a TPMS on an inner dual tire without the extension.

Because they often leak. Perhaps we are not communicating.

A long valve stem is needed for an inner dual.

An "extension" is not.
With an extension there are three places a leak can occur.
1. At the valve stem cap or PP
2. At the joint between the extension and the valve stem
3. At the joint between the valve stem and the rim.

George,
We have a long stem on our two inner duals and they just sit there begging for a TPMS to be screwed onto it which, of course, is what we do. It really couldn't be easier.

Paul,

I don't know whether to be happy or to be ticked off. We were at Les Schwab (one of the biggest tuck tire dealers in the northwestern part of the U.S. and when I asked about such stems they looked at me like I was goofy. When we bought our tires in Arizona from a pretty good sized dealer, he told me they do not exist.

People who have been RVing full-time for 8 to 10 years have posted about this topic and apparently do not know that such longer valve stems exist. Evidently, they are not commonly found, but I would sure like to have a link to them. I truly do not like the valve extensions on our inner rear tires. They have been problematic and whenever I need to remove a sensor on an inner tire, I have to hold the valve extension with a pair of needle-nose Vise Grips so as not to disturb the connection.

I would be so grateful if you would provide me with the source of these stems so that I can get a pair and have them installed.

Thank you for this information.

Herman Power Tire in Nac 936 564 8751 has the long stems, they put one on my inside dual, to solve the leaking issue with the PP mounted.
Not all big tire shops are created equal

I was at MOT planning to leave on Sat (after my normal pilgrimage to MOT maintenance earlier in the week). I took off the PP on driver's inside dual to add air and the entire long stem came out. I could not fish it back in so I called Herman. They removed the outside dual and fixed it. Great! I was still good to go on Sat.

Then I opened the door to the large bay next to the utility bay and one of the attachments broke. It took me and the Herman guy to get it partially closed.

No one at MOT on Sat, of course, so we went to the movie.

Monday morning the MOT guys did their thing and we were on our way by 10a.

Foretravel people seem to get to know their way around Nac ;o)

"No way am I going to buy new batteries from Pressure Pro."

George,
I don't believe that batteries can be replaced in PP. At least that is what I was told a few weeks ago when I had one shut down on me. On the other hand, I had a new sensor in my hands two days later and then I returned my bad sensor to them. It was a very painless transaction.

Paul,

Not to nit pick, I just want to be sure I am getting this right. Don't you mean to say that Herman Power had to remove the inner rear tire and dismount it in order to install the new longer valve stem?

In my case, Herman Power man removed the inside wheel and broke bead on one side, and was able to fish the new long stem in and mount it, air it back up, not a BIG deal for the boys that know how to do it, again all shops are not equal, some can make it look simple, some look like they are fighting a gater

George Stoltz asked: " What was the cost involved?"

George: I recently replaced all of my PP sensors, as they were 5 yrs, 8 mos. old and 2 of the batteries had died within a week of each other. Paul is correct: They do not replace the batteries. For $35/sensor they send you a brand new set. The total for 10 sensors was $365. They ask you to return the old sensors (pre-paid box) so they can be examined by R&D people at Advantage Pressure Pro. At that time I also ordered extra (10 in a package for $4) rubber inserts. Although they do wear out after a couple years, I have never had a new one not fit snuggly around the inner circumference of the sensor. It is also my impression that their function is to hold the Schrader valve down (open), so the pressure may be read by the sensor, not to keep the sensor air tight.

I have had my rear sensors connected to braided metal extensions for nearly 6 years without issues.

Thanks, Don.
I smell a little "gilding of the lily" in the phrase from PP about having R&D examine the sensors.

C'mon Pressure Pro. Really! R&D people are gonna test batteries?

While I do not find the $35 price per sensor out of line, for me when the time comes to get new ones, I will be putting my money on a brand that allows me to replace my own batteries and should SEND me free not SELL me rubber inserts to take care of a defective design. For the amount of money the Pressure Pro system costs, the very least they could do is send FREE inserts to those of us who have had problems. That, in my humble opinion, is one way to build customer support.

George,
The cost was $35. I thought they might charge the $50 of a new sensor and then refund $15 when they got my old sensor, but they did not.

I too am looking at installing a tire pressure monitoring system, but I learned something you might want to consider at the recent FMCA rally in Perry. I will be buying the Silver Leaf engine monitoring system in the very near future, and will run it into a spare 14" Toshiba laptop computer that will reside just to the right of my instrument panel. I will also be purchasing DeLormes GPS system that will feed into the same laptop and share the screen with the Silver Leaf. I learned at the rally that Pressure Pro is the only one of the TPMS that will also share the laptop screen with Silver Leaf, so you don't have to use a separate display panel for the TPMS system. Might not be important to you, but its worth a thought, and I love the thought of having all three on one screen.

Re: TPMS questions

Pressure Pro used through Silverleaf generally will not readout tire PSI without ignition key on.
So using dedicated Pressure Pro monitor has advantages, like using the monitor in a car when being driven separate from motorhome, in addition to receiving immediate alarm if someone removes sensors or slow leak notification.
We regularly check our Pressure Pro tire pressures while parked and as part of our get ready to travel check.
