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

Didnt need to use the extender to get signal from the toad vehicle for these.

Quality product.

Added to current system with six sensors Love security of monitoring all tires on RV and tow vehicle

A must if you are also using the TST Tire monitor. Was less expensive ordering additional tire monitors to go along with the TST kit, that comes with 4 monitors , than to order the bulk kit with 8 or 10 tire monitors! Thanks for offering this product at a great price! Arrived as promised and quickly. Would purchase again from this shop.

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.

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

They work great bought them for the smart car. They programmed into the main unit perfectly. Since we tow now we can watch to make sure all ten tires holding pressure.

Excellent TPMS. A bit complicated to set up, but quite doable with the instructions. Be sure to use the correct valve stems for wheel senders. Nice seeing in real time 10 tire pressures. TST offers the best customer service!

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

Great price ..... works and thats what matter, piece of mind
