TST 507 Tire Pressure Monitoring System, 2 Flow Thru Sensors for Metal Valve Stems by Truck System Technologies, TPMS for Caravans, Motorhomes and campervans

Easy to add to the main system unit. Gives good feedback on status of tires on towed vehicle.

We drive a 38 Class A motorhome and have had the TST TPMS sensors on all 6 tires for over a year. So when we added a Honda CRV as a tow car we needed these additional sensors for it. These are easy to program and give a very strong signal so we didnt need to use the repeater to get signal to the RV driver. In my opinion having a TPMS is a must have item for any RV motorhome and tow car and weve been very happy with the TST 507 model.

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.

I have the tst system but I needed 2 more pass through valve stem Monitors. They work prefect with my existing system. On time delivery product as advertised

Much larger than I expected. Easy to install and they feel secure.

Very good

Works goood so far

I bought this for my utility trailer as an add-on to the TST 507 system that I use with our 5th wheel. These paired up with my existing receiver without any issue. Even good quality tires that are within their capacity ratings and expected life span can fail, and my TPMS has alerted me twice so far when a tire was starting to come apart at 65 mph. The warnings came in time to get safely off the road before either tire failed completely.

You need to read the reviews on the TST 507 TPMS system these do not work without the monitor

I like these better than the banded interior tire models that break.
