I was shopping around for wheels for my car and it looks like Tire Rack has recently cataloged proper tire pressure sensors for the Mirage! (as recently as 2 weeks ago, the last time I checked) You can now buy a set of new wheels without swapping sensors and allow a shop to legally install the wheels and/or mount tires locally if you so choose.
This is great news, since TPMS is mandatory for all 2008-up cars and some regions will fail your inspection for not having a functioning TPMS. And no more annoying TPMS light!
