TPMS with internal sensor

Be aware that when the TST beeps that you've lost a sensor, that sensor may not have been in contact with the monitor for over an hour. It can take an hour or more of non-communication with a sensor for the monitor to finally beep. This is a known issue that some have with the TST system.

This last trip I happened to glance down at the monitor, I rarely watch it since I rely on the alarm, and noticed that I had one tire that was 10 psi lower and 5° cooler than the rest of them. We had left the campground about an hour earlier and all sensors were working at that time. While I was wondering where to stop and check things out, the monitor beeped indicating that a sensor had been lost. It was the one that showed the low pressure. I moved the monitor around and it picked up the sensor and showed the same pressure and temperature as the rest of the tires. It does happen.

I have the TST (I think). I got the removable ones that just screw on and you can replace the batteries. I have a 38 ft. fifth wheel and just leave the sensor on the center console. It works fine - maybe once in a while it drops the passenger rear sending unit/tire, but just hold it up for a minute and it is back. They have an extender you can put in the back window or in the front of the fiver by the battery if you need it.

I have been using the Pressure Pros since 2006 on a 34ft. Cedar Creek pulled by a 3500 Ram CTD dually but after a few years the units quit working because I left them on the rig and the batteries died (my fault). I bought a new set (10) and everything worked once again. This time I used some "white out" and numbered the units starting at the left front-RF-etc all the way around the truck and trailer. After another few years, the batteries started to fail on the new units so my friend and I used a Schrader valve and mounted it on a lathe and after ruining a couple of the oldest ones, we were able to CAREFULLY slice the tops off of the units and replace the batteries which we bought for less that $10 for a dozen. We used a glue to put them back together and a few of them weren't sealed good enough and when they got wet, they ceased to function but otherwise, it is a good fix and I love the piece of mind it gives me going down the road. The last time the sensor went off I had a blow out and was able to stop before any real damage occurred but it knocked a piece of the valance off the side of the trailer. I highly recommend these things and I've mounted the receiver on the dash with velcro without any problems.

I can't comment on the ones in the link, but I'm using TST internal sensors on my fiver which is 34 ft. I do not use a repeater. Have used the sensors for 4 yrs now. On several occasions, I have lost signal for the rear, street-side sensor (the furtherest sensor) but moving the monitor from dash to the center console and it regained signal immediately.

I have used Pressure Pro for over 5 years now on a 39' 5er and a F350. I mounted the receiver/monitor in the back window of the the truck and have not ever lost signal. http://www.rvtirepressure.com/

Thanks for the colicky . I'm not a big fan of those screw on sensors. I noticed the range the sensor would transmit wasn't listed.
Was just wondering if anyone had tried/ used them.

Maybe it's just a rumor but awhile back the internal TPMS for trailer tires had to be installed by a technician trained in its use. Would make having a garage repair a tire less likely. We went with the Pressure Pro.

My worry would be the range. I think it is meant for a vehicle, where each wheel sensor is only a few feet away from the receiver.
