Can someone school me on this please? I am about to put an old set of volvo rims on my Focus for winter driving. I feel like I have been transported into the future and nothing makes sense. The original wheels will communicate with the car when its parked? What? And learn? Who learns what? There is a wireless sensor inside the original rims? All I know is these old rims definately do not communicate or learn anything. Someone please tell me WTF is going on in terms a simpleton like me can understand? Thanks. I don't want my TP light on all winter.
