Stock TPMS?

Hi there,

So my 2023 Fuzion 373 says it comes standard with TPMS and display. The trailer did come with a TST 507 display it did not come with any screw on sensors. The trailer valves have yellow tips on them with the low tire pressure symbol painted on them. I am assuming this means they are TPMS stems.

Well before I open the brand new display up I wanted to see about pairing the sensors with my 2023 GMC 2500HD Tire Monitor display. I first tried the method of letting air out to pair them.. didnt work. So then I bought one of those cheap pairing tools off amazon... didn't work.

Are the stems specific to certain displays? Do I not even have TPMS stems?

Just curious.
Thanks!

The TPMS sending units are inside the tire and are integral to the valve stem, just like in your truck.

It will not pair to the GM TPMS system if the TPMS on the trailer is the TST. It is very likely that the TPMS sensors are not part of the valve stem but are clamped to the wheel inside the tires, so there would not be anything to screw on to the valve stems. https://tsttruck.com/507-series-4-in...7-int-4-c.html
