TST TPMS Question

[Dalsn1]

I purchased this TPMS system and so far after two 400 mile trips the system has worked perfectly with just one problem. I have trouble keeping the sensors tight. After each days travel i find them just starting to loosen up. Re tightening isn't a problem except for the outside duals that have very short inward facing stems these are problem as the wheel liner in the way. I am afraid to tighten them any more as the sensor may strip.
Has anyone used a small dab of blue loctite to help keep the sensors tight? Sitting next to the house the sensors never loosen up or loose air only after a day of travel.

Thanks
Steve

I use a small piece of teflon tape as a sealant and haven't had a problem.

Like Steve, I use a wrap or two of teflon tape on those I can, but don't have any on the inside duals. I found that my sensors loosened some on the first drive or two after installation (flat tire on toad the next morning after the first 300 mile trip!!). Since the first couple of trips, and checking & snugging them up after driving, I haven't had any problem with them getting loose.

The suggested use of the teflon tape is better. I would never use a Loctite product on the sensor's as you may not get them loose without damage.

I invested in a set of the stainless steel hose-like valve stem extenders for the rear tires. This made access for checking tire pressure so much easier and installing the sensor's.

Thanks for the suggestion, I will try the tape before our next trip.

The sales material says this system has an anti-theft device for the sending units. True???
Use of those devices should eliminate the "loosning" problem.
It certainly does on the Hawkshead System.

[StevePav]

The "anti-theft" device is simply the constuction of the sensors themselves. Each sensor has a thin, machined plate with two flats mounted on the tire side of the sensor. Inside the TST kit are two "tools" for installing and removing the sensors (you only need one, I suspect the other is a spare). The tool fits over the sensor and you use it to spin the sensor onto the valve stem. If you don't have a tool you'll probably destroy the sensor trying to remove it, hence the anti-theft label.

That's a good idea. I've had a couple come loose and lose a bit of air. On our last trip, my wife was woken at 4am up by the TPMS alarm saying a tire was getting low. She wasn't amused when I told her what it was

At camping world now gettng the TST system installed while getting a tire replaced. Will be interesting to learn the process and watch the system work. Glad we have a TPMS now since we've read some of the stories on here and other sites where improper inflation has caused some accidents.

Papa John, since you are having the system installed vs. DIY, make sure the installer gives you the TST tightening wrench as without it you may not be able to get a sensor off or retighten it if necessary. That is your tool not his! Good luck and enjoy your new TST system to the fullest, Ken....

[StevePav]

Ken's right, but make sure you get 2 tools since that is the number of tools that come with the TST TPMS kit.

Wow, I'll have to check the box tomorrow and make sure they are in there. Didn't even think about that so appreciate the feedback. Will let you know what I find out. If they're not in there, you can bet I'll be going back to see the service guy

Thanks
