TPMS Sensor Shelf Life?

[BMW Dom]

Bought these from RA for tire appointment of Tuesday. But the sensor is like 4 years old already??

Would you run them? Other option is to get the TPMS sensors from Discount Tire for 60 each compared to 100 for all 4 of these

Discount Tire will match price for same item.

They don’t have the same sensor

Not a problem. It should last at least one set of tires

Can you replace the batteries now before installing the sensors so that you have a fresh start with the sensors?
Or are the sensors sealed? I ask because IDK,

If those are for your BMW I'm still running the original TPMS sensors on our 2011 BMW 328i M-Sport, and they work just fine.

IMO, if the sensors you bought are BMW OEM or Huf branded, the 2022 manufacture date will not be a problem.

TPMS sensors don't initiate until turning - usually about 20mph. They have simple accelerometer circuitry. The battery is not being used up sitting on the shelf.

Batteries do have a shelf life due to internal discharge, so I wouldn't use a 20 year old sensor on the shelf, but a few years, sure.

I'll just use it! Probably only going to keep car a few more years anyway

Not sure if Toyota buy the same one as what TireRack / Amazon / RockAuto sells. Mine last about 15 years since car was build on both of my Toyota / Lexus.

Well I had them installed at Discount Tire and of course they are not syncing to the system ... always something.

And they did an alignment check and told me toe was off by 23 degrees but couldn't print the sheet out because the printer was out of paper and ink... sigh
