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

great add on for my existing TST system to add another trailer

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.

worked as described. Like the replaceable battery so not throwing away sensor anymore like the pressure pro system sensors. already saved a tire on my tow car

We just started using them and they are working great

I have the non-flow through sensors, recently the inside dually kept loosing pressure, it was a pain to get the sensor on and off just to put in air. eventually i had to replace the valve stem that was leaking.. i bought two flow through sensors for the inside dually tires. its a good choice,.

Worked great. Integrated well with my monitor

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 bought 4 new ones for my 5th wheel. I had a set since 2015 that worked well, but one stopped working last fall (even with a fresh battery). They work the same as the older ones, and program the same way. My old ones used a special tool to put on because, when tightened, the sensor was free-spinning on the base. The special wrench was needed to grab the base to remove them. The new ones are no longer free-spinning. They use a separate nut that goes on the stem first, then screw the sensor on, then use the special wrench included to back up the first nut against the sensor so it cant be removed by hand. The special wrenches for the older versions are not interchangeable with the new ones.

TST has saved my tires and large motorcoach from expensive repairs and damage not to mention our safety.

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