Before I brought my new wheels & tires to be mounted & balanced, I asked the garage to remove the old tires from the OEM sawblades.
Surprise, surprise, there were no TPMS sensors in any of them.
I suspect the previous owner had nuisance alerts for which I've read the early sensors were notorious.
I've always monitored my tire pressure since one of the tires had a slow leak so it's no big deal.
