The Tire Rack site says I'll have to go thru a procedure to have the car recognize the new TPMS sensors if I buy a totally separate set of tires and wheels (and sensors) for the winter.
They also offer an OEM Ford TPMS triggering tool for sale (add the cost of the sensors and the tool and the price is well into "WTF!" territory).
I can't find anything in my manual about how to get the car to recognize the new sensors. Anyone have an idea of how to do that, short of going to Ford ($, assuming they will even do it) or buying the Tire Rack tool ($)?
