TPMS purchasing

[George]

Hi Jim,

Please help me understand what you describe; TST TPMS. I know what TPMS means but not TST. On our previous fifth wheel trailer I installed a TireMinder system with four transmitters and a signal booster. Is this similar to what you are describing?

Thanks.

I just bought a 252RL today. The shop didn't know much about the TMPS prep but the tech was able to locate the repeater, yellow box with a red LED mounted to the drivers side frame just in front of the axles. The dealer sold me a 507 screen for $71 (good deal!) and had to order 4 valve stem pressure sensors, about $200. So I should have this all setup for about $300 once all is done.

I did a bit of AI asking about the red cap stems and here was the answer I got back:

• Heavy-Duty Stems: The red-core stems mean your wheels are structurally ready to have cap sensors twisted right onto them without needing to upgrade the hardware at a tire shop.

@jschenck See if you can get one more sensor. Having one on the spare is nice, so you can monitor the pressure in the spare too.

Now you tell me ... I just had my wheels converted to metal stems. Thankfully, that was only $15 for the stems and the install was free. The cap sensors have worked great. It's nice to see the temp and pressure at a glance.

It is just the repeater. The red valve stem covers are not part of a TPMS. I have used TST TPMS for over 10 years...love it!!

Hello Jim,
I recently bought the Alliance Delta 262RB and it came with the TST repeaters wired in. I like the idea of adding a TPMS - ideally the TST one - but I am wondering if the TPMS valve caps could be an issue as I guess they open the actual valve and depend on the tightness and seating of the valve stem cap to actually keep the air in the tire. Have you had any issues at all in the 10 years you have used these?

I have used the sensors both with valve stem and without. I like having the valve stem on the trailer, as it makes it very easy/quick to add/delete air before a trip. I have never had any issue with the TST sensors leaking. I did take my RV to a tire center to have steel valve stems installed. You need steel if using the sensors with valve stems that allow you to fill directly. If you just get the sensor without valve stems that allow you to fill directly, you can use factory stems.
