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

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

We just started using them and they are working great

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.

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.

Quality

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

Ive owned several different TPMS systems on three different RVs and TST is about the best Ive found.

Purchased to replace lost sensor. These newer sensors appear to be improved somewhat and work with the 507 receiving unit which is now 5 years old. Would easily recommend.

Works perfect Great Product.....

Replaced my older style flow thru sensors on my 26 ft travel trailer. Programmed all four sensors without any issues and installed each one at a time. However on my first trip the two sensors on the left side didnt provide any readout on the display inside my pickup truck on a one hour trip. The two sensors on the right side were OK, as well as the four button caps on my truck. Not sure why just the left side wheels on the trailer are displaying information.
