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

Working as advertised, shipped on time. It even came with extra gaskets.

Do not buy the color screen addition of this system as the tire pressure read out us in dark blue and almost impossible to see in daylight driving.

Same price as everywhere else. Work great. New design.

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.

Its a shame TST doesnt sell these in a two-pack. My boat only has two wheels, so Im paying for two extra sensors that I may never use.

I am satisfied with these TST tire pressure/temperature sensors. They are probably not dead accurate for either pressure or temperature but any gross outlier among your tires can be spotted and watched. After carefully filling all tires to manufacturers recommendations, the tire pressures on each axle only read from 0 to 4 psi of each other. Once driving, the pressures diverged more with tire loads, wind and sun effects . I like the immediate notification of a sudden air out condition or over temp condition.

Use these on my toad. They all worked fine with my existing TST monitor. Removed the anti theft feature to make them smaller......( I remove them when in doubt....and when the trip is over). Also I dont program them in any special way as far as position....all I want is a warning if ANY tire goes low ANYWHERE on my RV + the toad............dont care which one (I plan to stop and look things over ASAP for ANY monitor warning. I have them on rubber valve stems (fairly short ones) on my Kia Soul ...... so far (2000 miles) no problems.....knock on wood.....dont want to have to install metal valve stems.

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

They did their job in the first few weeks of installing them on our tow vehicle. We tow a Nissan behind our RV that picked up a nail in the back passenger tire. We lost ten pounds and were alerted of the problem before we ended up with a blowout while towing. So I highly recommend them if you are towing a vehicle behind your RV. We have pass throughs for the RV itself and love those as well.

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