Great deal on TPMS sensors

Hi everyone, just wanted to let you know rock auto has a vendor close out sale on our TPMS sensors. They have both frequencies available & are $19.79 each, normally almost $50 each. They are OEM replacements. Siemens no longer makes these & they now come from VDO Continental. I just received mine & they are 100% authentic & OEM. For about $100 you get them shipped to your door. Not a bad investment for the inevitable failures we will all have.
Cheers everyone.

So how does one find the information as to which frequency they have in their car, 315 or 433 MHz ?

The problem with Rock Auto is they buy out stock lots that may have sat on shelves for years. Since TPM sensors only have a finite lifespan how many years of use are you going to get out of the discount parts? I'm cheap and have hesitated...

My understanding is that US cars have 315 MHz

A question would be , how old are these sensors. Battery life is usually about 7 years and sometimes more or less. I don't know how to verify age but if they are a few years old it will only limit their usefull life. If you use a TPMS tester it only gives you , battery good , low battery or bad battery.

If Rock Auto lets you return them, you can check the date of manufacture, which I think (don't know) is on the TPMS and determine if it's worth the effort. I would use 7 years as a target life span if it were me.

The ones I received from Rock Auto are mfg in 2016 so I’m fine with that. That’s still 7-8 years of battery life.

While I agree with the thought of Older is Bad, it would also depend on whether or not a person plans on keeping the car for 5+ years or not. It seems cheesy, but if a plan to sell in fairly near future is in place, older sensors to get rid of a fault (or possible imminent) is totally doable.
