My understanding is that use of a monitor on rubber valve stems is bad news. All recommendations are for metal valve stems when installing an air pressure monitor.

I can see why... the weight and the tire rotation would tend to continually flex the rubber stem and eventually cause the stem to crack and leak.

X2 .
The centrifical force would be too great and over time you'll have an issue. The smaller the tire, the greater the force at high speeds.

I have steel valve stems on all 11 of my wheels-

- 7 on the coach. I have a mounted spare.

- 4 on the toad.

Several folks have asked how tight do you put these sensors on? I would say SNUG, not TIGHT.

Having the system for about 3 years now, I have a suggestion for all you folks.

Get an old empty spray bottle, like a window cleaner, and put some Dawn dishwashing liquid and water into it. Everytime you adjust the air pressures and remove/replace the sensors, spray the sensors and stems with this solution- let it sit for five minutes or so, then go around and look at all the wheels. If you see bubbles forming, readjust your tightness until the bubbles are gone. If it's still leaking, call TST and have a new sensor sent out. You'll have an airtight, dependable system then-.

I speak from experience about this-

Good luck to all,

I have had a tire monitoring system since 03 and both my toads had the rubber valve stems and I have never had a problem.

Some folks have issues with the rubber stems, others, like you don't. The prudent thing to do is have a metal, non flexible stem to support the weight of the sensor from any tire monitor system. Is there a possibility of the rubber stem breaking while underway, yes, would a metal stem be stronger, yes. You won't be stopped by the TST police if they find you with a rubber stem, but should it fail and you loose the sensor, along with the damage caused by the failed tire, you would have been warned that a metal stem was suggested, and recommended.

I am considering a TST system but a little confused. As I see it there is 510 system, a new 507 system both of which will monitor upto 22 devices. There is also a system that will monitir up to 34 devices, which I do not see a model number listed.
Which of these would be the best solution on a MH? Looking for simple reliable use. I certainly will not ever need 22 senders.

The 507 system is the newest technology with user replaceable batteries.

I use an 8 sensor scheme on my setup due to the use of Crossfires.

I have the short stubby rubber valve stems and have many thousands of mile on them with the TST sensor's attached and have never has one issue for leaks. I did try to get metal stems once but because my toad has fancy spoke aluminum wheels from the factory no one had them in stock.

I can finally answer the question- "How tight do I put these sensors on?"


Mix some water with liquid dish washing soap in an old, empty spray container-





Install your sensors "snugly" and spray with this solution. Go have a cup of coffee, or a adult "libation"- About 15 minutes worth.

If no bubbles, hose off the water/soap solution and your good to go . If bubbles appear, tighten slightly more and repeat these steps.

Good luck,

Believe me, I've learned this the hard way
