The TST system does have an rapid air loss alarm.

Even so it can take up to 5 seconds for the alarm. When I was removing my TST sensors for winter it took a couple about 5 seconds for the alarm. In case of a wheel loss or valve stem failure at 55 mph you will be way past sensor range in 2 seconds.

um, yes it does, I had a bubble in the outside skin that blew dropped my pressure from 88 to 62 instantly and set the alarm off.

I went with the threaded rubber seat all metal stems. You can get many different lengths, so they don't have to stick out too far.

I have a long bed, crew cab truck, and a 36' trailer, and I've never had an issue needing a repeater. I can take my receiver in the house, while waiting for all the sensors to check in, and still get a signal from all. Mine is the TST, they are made for semis, so I don't understand people having a need for repeaters on RVs. I don't.

Seems I can't find a metal stem to fit my wheels. I would be open to suggestions. The nut on the outside won't fit down into the recessed valve hole on the wheel.

I also don't need/use a repeater.

Actually what you're seeing is the main problem with the TST system: it can take up to an hour or more for the monitor to see that it has lost contact with a tire sensor. I need to add the repeater since I have lost contact with a sensor or two and contact was reestablished without the alarm sounding. Pure chance that I happened to notice it, but the sensor was out of contact for about 45 minutes before it connected again.

I have the flow-through sensors and would not bother with them again. They are so restrictive that it takes forever to add anything over of a pound or two of air pressure. Adding 5 psi takes a lot of patience. I take the sensor off if I have to add more than just a couple psi.

It's nice that you don't, but others such as myself do. It varies from application to application. I have my receiver mounted low on the console of the truck, so the signal is probably being blocked somewhat by the truck's tailgate, the rear metal wall of the cab, etc. If the receiver were on the top of the dash, it might work OK. I do know that when I've not plugged in the repeater, I've gotten lost signal alarms on 2 of the 4 trailer tires within 30 minutes.

You definitely need metal stems, and not just the stems with metal stem and snap in rubber seat. I had those on my truck, and thought they would be good enough. The rubber seat broke. I went with the threaded rubber seat all metal stems. You can get many different lengths, so they don't have to stick out too far.

I know of three people who were saved a big problem from their TPMS. I run TST 507s and it works well. My only complaint is the screen on the monitor reflects glare and can be difficult to read while wearing sunglasses. I forgot to turn on the repeater on our last trip and on the second day got a blast from the alarm reminding me when one trailer tire wasn't reading.

Yes they really work to: notify you that you are getting a ticket, correction, notify you that there is a potential tire pressure problem. It's as if you were to check the pressure on all your tires every second of the trip which, of course, is impossible to do any other way.

I use the flow-through sensors on the 507. Since I use them on the truck and trailer, I really don't feel like the standard sensors would work for me as I would have to dismount the rear duallies on the truck to add air to the inside tires. I haven't lost any sensors due to road hazards in 2-1/2 years of use.

I also use the repeater due to the length of our 5th wheel and the placement of the monitor/receiver in the cab of the truck.
