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

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 tow an expedition behind my Mountain Aire- they work great! I am within 1# of my digital gage. I didn’t put on security nuts. I remove when I unhook. Then check and air up before we start to tow again. I have a repeater on RV

Monitors are working great with original TST system. Now I can monitor my dolly and car behind my motorhome!! No worries

Shipping was fast , install easy, set up was easy with well written directions

Just back from 1500 mile trip and these worked great on my trailer.i felt much better rolling down the road and able to keep an eye on my tire heat and pressure

I had the old style cap mount and would have to remove them each time to air up the tires on the RV. These are so much easier. Accuracy is spot on also.

This is not a recommendation for this manufacturer. I have only had their monitor for a few months and it seems to work fine. It is a recommendation for the product. I have had tire pressure monitors for over 10 years and they have alerted me to serious tire problems several time which potentially averted major tire failures while driving. Blow outs can not only cause major accidents, but the shredded tires can cause thousands of dollars of damage to your coach, even if there is no accident. Ask any coach manufacturer what it costs to repair damage to compartments and side walls of coaches after a blow out.

good to have these on our tow vehicle as at a glnce we know the status of our tires! Prompt delivery.

Was able to set it up on my 2012 Honda CRV.

I have 6 sensors on the motorhome placed 8/19 but I have a towed vehicle to monitor so I got four more sensors in the Spring. All 10 sensors work great rain or shine. The monitor has caught two leaks and alerted me to excess brake disc heat while towing. The rig is much safer with the TST pressure/temperature monitors and only need annual battery changing.
