Recommended Flow Through Tire Sensors for a TST TPMS 507 System
Updated 11/12/2025 | Published 11/10/2025
Question:
I currently have a TST 507-D-C.H monitor that I purchased Oct 2022. I use it now for monitoring only my TOAD tires but I want to add 6 sensors on my motorhome. It looks like either the E22 or 507-FT-S2 sensors will work with my monitor. Is the 507-FT-S2 sensor an upgrade? Thank you

Yes, they are Bill and thanks for the information. The Flow Through Tire Sensors for TST TPMS item # TST-507-FT-S2 are going to be a solid upgrade over the standard replacement option item # TST-507-RV-S4.
The Flow Through Tire Sensors for TST TPMS item # TST-507-FT-S2 are going to allow you to adjust the air pressure on your motorhome's tires without removing the sensors. These are only sold in a 2-pack so you'll need to purchase three of them.
What kind of valve stems does your motorhome have?

Thank you Jerred. The valve stems on the motorhome are metal. The valve stems on the toad are rubber. We use non-flow thru sensors on the toad. We have used TST TPMS since 2014 and have never had a problem. Great product and customer support. Thanks again
