TPMS - Part Number 2015-2020 vs 2021+

Hey everyone, I just purchased a set of 2021 RST wheels that I put on my 2018 Tahoe, and the fitment is perfect. I am trying to figure out the TPMS situation now, and dealers are completely useless as they will not provide part numbers over the phone, and they want to gouge you on the price to buy them through the dealer vs what is available online.

Based on my research, I am seeing two different part numbers for the 2018 Tahoe, each with a different frequency. The dealer I spoke to on the phone did at least confirm that the frequency for the part made for my car was 315mhz. Interestingly, that appears to be the frequency that the 2021+ vehicles use.

I have read a lot of threads about how the 2021+ sensors do not work with the previous gens because of the difference frequency, but is there a way to make them work given that these are the same frequency? One nuance I did notice is that the 2021+ say they are auto-learn, which may be the reason they are not cross-compatible.

Anyone have any experience with this?

The part number provided by Chevrolet.com for my Vehicle was 13540604
The part number ACDelco site has for the 2021 is 13538759

Thank you!

Uh, from my understanding, the older (up through 2018) vehicles used 315mhz and 2019+ used the 433mhz. Some 2018 models used 433mhz also because they switched mid year.

Auto-learn has nothing to do with the sensors I believe, but with the way the vehicle electronics detects and programs for their positions on the vehicle.

I purchased the part number 13540604, and they worked like a charm. 315mhz.

And also good to know that the new wheels fit the older machines, thanks for posting this.

I did the same exact thing, 2021 RST wheels for my 2018 YXL. Discount Tire swapped them out for me for $80.
