I have received the official quote from Tesla. OP if you can update the first post, that'd be great:
Wheel $250: 1234221-01-A - WHEEL, 18X8.5J ET40, PINWHEEL MAGNETO SVC
Aerowheel Cover $38: 1044231-00-B - 18 INCH PINWHEEL CAP
TPMS Sensor $85: 1074812-00-B - TPMS, WHEEL SENSOR, 433 MHz BLACK VALVE STEM WITH BLACK CAP (soft cap)
TPMS Nut $1: 1038975-00-A - TPMS NUT, BLACK, CONTI
I guess I will order the 4 rims and mount the X-Ice or Blizzak myself. There is really no need for 2nd set of aerowheel covers.
