TST 507 TPMS Signal Repeater - Solve Signal Issues and Extend Sensor Range for Your Tire Pressure Monitoring System

I installed the Tire Pressure Monitor System By TST - W/6 Sensors, plus the TST Tire Pressure Sensor Tow Car Pack for TST 507 Systems, plus the Repeater For TST Tire Pressure Monitor System - TST507REPEATER. Once installed and operating, this system shows the continuous PSI and Tire Temperature for all six (6) tow vehicle (dually) tires, plus all four trailer tires. TST has newer and more advanced systems than what I purchased. Nevertheless, this system is giving me the continuous tire pressure and temperature for all tires, I used the recommended setting of ten percent (10%) below normal inflation, twenty percent (20%) above normal inflation, and a maximum tire temperature of 158 degrees fahrenheit. Once any of these parameters are exceeded, you will get a screaming loud and visual alarm. You can monitor visually each individual tire as you are driving. The monitor has two different mounts for driver convenience. On a 1 to 5 start rating, I give this system a five star. It works as advertised, and I am absolutely confident that if there is a problem with any of my tires, I will know it BEFORE a tire blows out. The monitor with six sensors was $261.23 on Amazon, the additional four sensors was $170.00 on Amazon, and the Repeater was $50.00 on Amazon - Total $481.23 - peanuts compared to the cost of a blow-out on a travel trailer, the inconvenience, replacement tire and rim, and damage to your rig. If you are towing a travel trailer, you really do need the repeater. PROS: The system works, period, full stop. Programing and installation is fairly simple. Read the directions! Inexpensive compared to other units. CONS: The Monitor with six (6) sensors is an older model. It is roughly 2016 vintage, and when it arrived, all six sensors had dead batteries. I contacted TST directly and they did send me new batteries, and new rubber gasket seals, which need to be replaced after changing the batteries. So, other than the mild inconvenience or having to replace the batteries, there was no additional cost. Installing the repeater required that I install a switch in the line, then directly wire it to my fifth wheel batteries. There are other methods for wiring this repeater, however putting a switch in the positive line makes using this system vary simple. If I could make a recommendation to TST, it would be to sell the Repeater with an on/off switch preinstalled. Here are the links that I used for my purchase. You should look at newer models to decide which is best for your particular needs.

There are a lot of TPMS systems. Not all are created equal. There are lots of devices competing for RF frequencies. A weak signal and the receiver can't/won't connect to the transmitters in each tire. I have a long bed pickup-was losing connection with my 21ft camper and then bought a 5th wheel. I can tell when I forget to turn on the booster. I lose signal/connection and have to fix it at the next rest area. With the booster my connection/signal is strong and reliable. The last thing I need is losing signal and having a tire failure I'm not even aware about. This is well worth the cost.

Has proven to be reliable and does the job. 65’ behind and had a good signal.

I have a 40' motorhome and tow a Jeep. I used to have issues with the rear duallies and Jeep sensors occasionally dropping out, especially when the batteries in the sensors were approaching the end of their life. I added this under the main bed (where the breaker/fuse box is) and identified an unused 12V line. I don't think I've had a single dropout since then. I overheard someone walking to a rep (not sure if he was an actual TST rep or a vendor) at the Tampa show. It blinks any time it's relaying the signal from *any* TST sensor within range. If you're in an RV park, expect it to be blinking quite frequently.

Easy install works great

Only that it works perfectly.

First of all this repeater worked perfectly and as advertised. I have had the TST 507 System in my 40’ mh and Ford F-150 toad for about 3 years with no need for a repeater. I just upgraded the display monitor to the color version and that’s when the trouble started. The sensors on both the tow vehicle and the motorhome would periodically not report. I replaced the batteries on the sensors without success. I added the previously unnecessary repeater and everything now works again.

With this booster, my TST TPMS sensors reliably transmit to the display in my truck. I installed the booster inside a kitchen cabinet in the fifth wheel and included a low profile switch to control 12-volt power to the booster.
