TST Tire Pressure Monitoring System

[hammerdown]

Passing along some info about my TST 507 TPMS. I do not recommend this system, I have had it for a year and a half and have had nothing but problems. First one sensor went bad then two months later 2 sensors, then two of the buttons on the monitor stuck inside. TST replaced or repaired everything under the warranty (I have a two year warranty). Now one sensor has died and the monitor buttons stuck again. I am waiting for repairs or replacement from TST. The warranty expires in July and it will cost $50 for each sensor and I don't know how much I will pay for monitor repairs. FYI.

That's really odd since most posts I've seen on the TST 507 system have been positive.

I have the 507 system that is only a couple of months old. I have the sensors on my truck only at the moment since I haven't moved my 5'er, but that will change in about 5 weeks when I head back to Florida for my summer host position.
The sensors and monitor are working flawlessly on my truck.

I have the 510 system w/ 8 sensors in use for about 2 months. Have had no problems.

I've had my 507 TST system for a year and have not had any issues.

We have only had our TST 507 System for 4 months now, no problems at all

Got a low pressure alarm today on one of my trailer tires. Turned out it was a leaking valve stem that had been changed out yet. No damage to tire or trailer.

Tomorrow, I will finish changing the rest of them out.

I have the TST 507 system and it saved me last week. The park where I am currently hosting was evacuated due to tropical storm Debby. I moved 30 miles north for a couple of days and then moved back. The night before I moved back I checked the air in my 5'er tires. I normally do this in the morning, but this was a very quiet park and I was hooking up and leaving early so I didn't want to make any excess noise in case I had to run my compressor.

I hooked up in the early am and started out of the park. I had gone maybe 50 feet and the 507 alarm sounded. Right front trailer tire. I went ahead and left the park and stopped on the road right outside the park entrance. Sure enough, the right front tire was down 8-9 psi. I started my generator and compressor and aired it back up. Replaced the 507 sensor and drove back to my host position park. This tire is still at normal pressure after over a week. The only thing I can figure is that when I put the sensor back on the night before I didn't tighten it down adequately. Regardless of the cause, it saved me a problem on the side of the road or at the very least of running a tire with low pressure and causing an overheating issue.

I'm very happy with my 507 system.
