Anyone using the tire pressure monitors that screw onto the valve stem? I am looking at the non electronic type that have the RED, YELLOW, RED indicators. My trailer tires run 50 psi. If so have you had any problems or brand recommendations?Thanks

If they're not screwed on very tightly, they'll leak. You're better off with a gauge.

I had screw on ones that were a pain. They always leaked. I was always having to get out the compressor to pump up a few tires. I took them off and installed the double seal caps that allow you to easily measure tire pressure with a gauge, without removing the cap. Now I never have any leakage and it easy to measure pressure before hitting the road.

If you have rubber stems that are long, the TPMS unit, at speed, can flex around possibly hitting the rim or cracking the rubber stem. I'd suggest metal stems first if you don't already have them.

I have used TST 507's since 2012 with no leaks, no problems. Well, one problem. About a year after it went out of warranty, the receiver stopped working on battery. It would only work if plugged in. I called TST to ask what battery they used so I could buy a new one. Even though the unit was out of warranty, they sent me a new receiver for free. They even apologized that I had to re-code the new receiver to the sending units.

Been using TPMS for 8 years, 1000's of miles towed. Never a leak.

My TST 507's require metal valve stems. 4 years with NO issues other than replacing the transmitter batteries last year as a precaution.

I've not heard of anyone have the color changing caps that haven't complained that they leak. If you want a TPMS, buy one that actually works.
