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

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 like these better than the banded interior tire models that break.

Mounted on tow car behind motorhome. Works as described

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.

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

Add ons to my TST 507 tire monitoring system. Works like a champ! Would highly recommend to anyone towing a trailer.

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!

They seem to work well. I would however make sure you use the security nuts that come with it. I didn’t and one of the caps worked itself loose. Lost air immediately in the tire. Once I put the security screws on we ran about 2000 miles with no issues

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

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