TST 507 TPMS...A Review

[Rbertalotto]

I ordered a 4 channel/tire Truck System Technologies 507 TPMS tire pressure monitoring system from www.TechnoRV.com . Great price, free shipping and I had it in two days!

PACKAGING:
Nicely done with lots of extra O rings for when you need to change the batteries in the tire sensors in a year or so.
A cigarette lighter cord and a hard wired cord is included.
A dash board mount and a suction cup window mount is included
Three different installation instructions are included. Seems they kept writing instructions to make it easier. The single sheet that looks like the last iteration was the easiest to follow, along with the TST YouTube video. TechnoRV also has a video on their web site to aid in programming.

SET UP / PROGRAMMING:
I suggest you view the number of YouTube videos available (Google Search) before you do anything. The programming is a bit confusing as it uses a relative few buttons to do multiple functions. If you go slow and be deliberate, it is quite easy. If you can't figure it out, this is why God invented 12 year old grand children!

OPERATION:
I only installed it on my pick up truck. I'll order sensors for the trailer once I'm sure it is accurate and robust enough.
Sensors were programmed and installed on the four tires. I did not replace the rubber valve stems with steel as suggested by others. Reports from others is that the sensors are so light they do not add stress to the valve stems. I agree. Time will tell.

The kit is available with standard (you must remove to add air) and "Flow Through sensors that you can add air without removing the sensor. I went with the NON-Flow Through sensors. I'll have to remove them to add air if needed. Time will tell if this was a good decision. But on my truck the valve stems are about 90 degrees perpendicular to the tire and I had concerns that the longer "Flow Through" sensors might get damaged on curbs or when I take the truck on rough roads.

The system came up and started to send PSI and TEMP immediatly. To test it, I lowered the air pressure and raised it with my compressor and in both cases the reported PSI was extremely accurate and the alarm sounded at low and high PSI parameters I set. The temperature is reading the exact same from each tire (37 degrees in their static state)

The interesting thing is the monitor is sitting here in my office, some 100' from the truck, through a number of walls and an aluminum garage door and it is reading fine. This leads me to believe that it will easily work on a relatively long trailer tow vehicle combination.....If not, an amplifier/repeater is available to boost the signal from the trailer.

All in all I'm very impressed with the quality of construction and performance. The monitor has the feel of a well built cell phone. Nice glass or heavy plastic screen, I can't tell which. Brass antenna connections. Very secure power cord plug/jack.

The tire sensors include anti-theft collars that I chose not to use. Maybe I trust folks too much. We'll see

Hope this helps if someone is thinking about getting a TPMS

Wow, you bought those about 10 years ago then? What part of the warranty didn't they honor? Did the monitor go bad? Sensors? Batteries? A little more info would be great.

[buc1980]

When I bought the monitors they offer me that warranty may be because they just open the business.

[Ron3rd]

I've had the 507 kit for about 5 years with no problems, works as advertised.

[fj12ryder]

Thank you Dck A. Nice to have that cleared up.

A vendor simply answering a question about their product is not against the forum rules. A blatant "for sale" post is against the rules.

[fj12ryder]

A little explanation could be in order.

What part of the warranty wasn't honored and why not? What company? TST? The TST website specifically states that the warranty is for 2 years? Where did you see the lifetime warranty?

[buc1980]

I am not satisfy with this company.I order a TPM with life time warranty but after 2 years they don't want to honor the warranty.I give up with them.Be careful with them.

Just for everyone else's enlightenment since there is also an ongoing PM between Sarah Lichtman and me, my sensors work immediately if I take one off the valve stem. That sets off the "Low Pressure" alarm. But if I take the tire off and move it out of range of the monitor, it can take an hour before the monitor notifies me that my tire is missing. During that hour while the tire is out of range I can remove the sensor and there will be no notification of "Low Pressure". Not a good thing IMO. Just too long of a time lag.

That seems kind of dumb. I was hoping to see some kind of reply from the equipment supplier. Telling them they can't reply just leaves all of us guessing.

This is a typical repeater issue you're having, I promise.  Very simple fix and you will be 100% confident in your tst system.  Once you have the repeater plugged in, just  take one off and you'll see how fast you receive an alert.  You will get immediate notification of signal loss or any other tire issue.   I stand behind our system 100%.  I've never  seen an instance where we couldn't make it work, and make it work well.  All you have to do is let us know what's going on.  It's normally a very simple fix, even if it doesn't seem so at first.  Anyone else having this issue or any other issue, feel free to call me.  678-725-4497

And it's my pleasure to be here.  Glad to see all the support.

[fj12ryder]

I don't have the repeater, but my main concern is the length of time for notification of loss of signal. I can see losing contact for a half hour and then regaining contact, and you'd never know that you had been traveling for a half hour with no protection.

I realize that the repeater will probably solve the issue of loss of signal, but how can you tell, if it takes an hour to notify you? An hour is a very long time to go without knowing you have a tire or two that is not reporting. Five to ten minutes seems like a better time frame.

BTW thanks for posting on the forum, nice to know that some companies are concerned with their products' performance and reliability.

[SarahLichtman]

And when you drive away from the monitor, that often happens. Any sudden change will alert right away. When you drive away slowly, it holds onto the last reading, but that should never be the case otherwise. I'm thiking you have some other issue that we can work out to make your system perfect, such as a repeater.

[SarahLichtman]

Hi Howard,
I'm genuinely sorry that that happened to you. Are you using a repeater?

[fj12ryder]

I can personally attest to nearly an hour's worth of travel before the system alerted me to a lost sensor.

About 45 minutes after leaving the campground one morning I noticed I had one tire that was not giving the same readings as the others. It was showing the same readings as it had when first leaving the campground nearly an hour before. I was looking for a place to stop and check things out when it beeped and showed no reading for the errant tire. Before I could stop and look at it, the next check showed the tire sensor had regained contact and now showed the same temp and pressure as the other tires. It had been out of contact for way over 30 minutes with no notification of that fact.

An easy way to check the length of time is to simply leave the monitor on and drive away from the trailer. It will be nearly an hour before the monitor alerts you that it has lost contact with one or more of the sensors. That's a long time.
