Now, you all have me in a "Search and Find" mode for my valve stem tool. Hmmm... Where did I use it last?

[SpringerPop]

If you ultimately find that you have to replace it, Snap-On has a pretty-good one for under five dollars.

EDIT: I just checked, and it says "currently not available". Uggh...

The tire-goop company, Slime, has one, though. Available at auto parts houses, annnndddd..... like everything else, Amazon has it.

Under four bucks, but "imported".....

Almost bought one at NAPA for $3.49, but thought I'd look in a couple more places.

Ok, this thread has me interested and I'm getting a set for my rig but now another question comes to mind. Did all of you with this system have your tires rebalanced with the sensors mounted like SpringerPop did? Is this common practice? I'm getting new tires this next week and need to know if this is a plug and play system or do I need to wait on the tires until my system arrives?
Thanks
Ron

Hey Ron , mine were plug and play.

[Dunner]

Mine too.

Thank you Cliff & Dunner

I am planning on getting the 507 system for 6 wheels plus 4 for the toad. I will also be at the FMCA rally in Indy in August. Will your company be there? I would wait to get it then.

We have six different gauges ranging from stick gauges to very expensive digital gauges.

Every single one of the gauges we use came with an accuracy disclaimer professing accuracy within +/- 2 PSI.

The variances between the gauges themselves vary up to six PSI on the same tire, within our warehouse, completely unaffected by outside stimuli such as heat, sun, etc.

If your shrader valve stems are not straight, this could cause a slight skew in your readings.

Our system is accurate within 1.5 PSI, so knowing what I do about gauges, if your gauge and your system are within about 4 PSI of each other, this is an acceptable varience.

You also might try tightening your sensors another revolution as they simply may not be fully depressing the shrader valve which will also cause a skew in your readings.

I will be happy to discuss this matter further with you. Just give me a call at your convenience.

Thank you!

Hi Dan,
Y'all just sold another 10 tire system. Looking forward to getting and using it.

Bought a 507 system about 2 months ago and have never had all sensors responding at once.....sometimes takes 30 minutes to show display on rear wheels and will stop working enroute which triggers an alarm. I removed the sensors and threw them in my toolbox, waste of money for me.....Glad to see many others have good service from their systems, just snake bit I guess.

[CLIFFTALL]

The owner of the Co has personally jumped in to assist when trouble such as yours arose. Why not give him a chance. He will return your email or phone call. It's a lot of money to sit in your tool box. Just a suggestion!

[greystroke]

I agree Ihill. Give them a chance. I am 10 for 10 on my sensors.

I would check the sensors by individually installing on a wheel that responds all the time. This will check the sensors. Valve stems could be a problem. I have had some bad ones due to over tightening them by the tire people. Could be your monitor. Let Dan help you. A working system is worth having. Especially on the toad.

--------------

May 22, 2012:
The 507 finally arrived this afternoon, which allowed me to take the sensors to my tire guy, who could now balance my new Maxxis tires.

Brought them all home and decided to activate the system. The YouTube videos were almost more helpful than the written instructions, and I had all the sensors "paired" with the display with no problems at all.

However, after ensuring that all the tires were at the same pressure, and setting the upper and lower limits, I couldn't get two of them to display anything at all. The other two worked "as advertised".

After noting that the two that worked had released "just a bit" of air prior to the gaskets sealing, and the other two non-operational ones did not, I determined that those two were not depressing the Schrader valve.

Hmmmm. I loosened the valve out to the point that there was air leaking past it a bit, and screwed the sensor back on. That resulted in the air just continuing to leak when the sensor was tight! What 'da heck????

I finally determined that any of the sensors would work on the two stems that worked initially, and none of the sensors would work on the two stems that were dead initially. Now I was getting somewhere!

I'm a tool junkie, so I have the tool to chase the threads on a valve stem. One of the functions is a thread "die" for the outside of the stem. If anyone's interested in trivia, it's a 0.307 x 32 thread. (How's that for an obscure size?) The tool looks like this:


I have determined tonight that my tire guy uses cheap (where do you THINK they were made?) metal valve stems. The O.D. threads WERE NOT THREADED FAR ENOUGH (and were slightly tapered), and the TST precision-made sensors wouldn't screw far enough on to depress the Schrader valve. After using the die to correct the errant Oriental threading job, the entire system is now playing a "right-nice tune".

I'm going to let it play overnight to see if there are any slow leaks.

Tomorrow, I'm taking my two spare tires to him to break apart, install metal stems, and balance.

I'm also taking that die with me, and before they go into my spares, those new stems are getting properly sized. I don't wish to re-discover this problem on the road somewhere!

Hopefully this helps someone, somewhere......

ihill, did you read this post?

Like others have advised, call TST. I have found them to be very responsive and customer oriented.
