Also, the computer tells you that you are using run flats if you let the PSI drop down below a certain threshold (happened to me shortly before I had these changed).
Nope. M3 doesn't come with run flats
TPMS is telling you that your tire pressures have dropped by at least 10% from their reference pressures (when you reset TPMS) - this light coming on has nothing to do with RFTs!
