Will TST 507 Sensors Work with 770 Monitor?  

Updated 03/05/2026 | Published 02/28/2026

Question:

Will these tst507 sensors work with a tst 770 monitor? Only need 1 sensor just want to be sure it will work. My old ones look just like these but the date code is what matters? Thanks

Hey Lark, this is a great question but yes the 507 sensors like the part # TST67FR do work with the TST 770 monitor like part # TST64VR since all that matters is the date code like you mentioned. If the sensor is made after 2019 (what we offer definitely has) then for sure the two are compatible as the 770 monitor is backwards compatible. How do you like the 770 setup?

I purchased one for the spare tire, had a blowout on the way back from a camping trip. Since I was replacing the tires, I had the tire shop add the new sensor to the spare tire. You can program the new sensor prior to having it installed. Works fine, I just have to remember that when the monitor gets to that tire, the temp is going to be cooler and the pressure will not change like the other 4.

I use the flow through because that way you can air up without removing them, but you need to just know that you must run Metal bounce stems do the added weight farther out the company also suggests the same thing.
