TPMS for 297RSTS

**travelinglamberts** · 03-03-2021, 01:04 PM

I'm looking to get TPMS for our 2020 297RSTS. What is the difference between flow through sensors and Cap sensors? I think I have metal stems if that makes a difference...anyone have the same GD as me and have a recommendation? We're prepping for a 1600 mile trip...would like a little extra peace of mind.

Flow through allows you to add air with the sensor attached

The flow thru sensors allow you to add air without removing the cap. I have a 2018 version of the 297RSTS and I use Tireminder TPMS and I am quit happy with it. You will likely need the signal booster as well so that you always have a reading. I bought the flow thru addition for the tireminder system as I got tired of pulling off the sensor to adjust the air pressure.

I would high recommend you get a flow thru sensor or adapter.
