Well I have had my new Wheels and Winter Tires (yokohama IG20) installed on the ST for 5 days and about 180 miles and no TPMS light has come on? (knock on wood) I had Discount Tires Direct (DTD) install the TPMS sensors on the new wheels ($168) and all I did was remove the OEM wheels and tires and install the ones from DTD.
Still no TPMS light is been 10 days :)
knock on wood again...
Update Still no TPMS Sensor lights and its been two weeks, kn on wood again, guess the system recognized the new sensors with no reset. Go figure.
