Curious. My suggestion is the TPMS system is pre-set up for the event a tire goes flat and a non-TPMS spare is put on. Not seeing a single TPMS but still seeing three working TPMS sensors then the system assumes a spare is being used since the car is still driving.

However that hypothesis makes no sense since our cars come with run flats and the TPMS programmers would not have thought that far ahead.
