Re: Run flat winter tires

Nothing.  The tire pressure sensor isn't really a pressure sensor.  It
works 
off of the anti-lock braking system wheel speed sensors.  The "tire 
pressure" sensor compares diagonal wheel speeds (i.e. Front-right and 
Rear-left) to each other, and then compares that difference to the value 
that's "set" when you reset the system (button under the E-brake lever). 
Therefore, it doesn't matter one whit what kind nor size of tires you use.
