So just to clarify the weights of the wheels and tires you list in these pics are the OEM 19" M3 wheels with stock PS2 tires? (or what do you mean by "but tires are 20mm wider"?
If so, the Tirerack lists the stock PS2's as 24 lbs front and 25 lbs rear.
So the OEM 19" M3 wheels weigh:
23 lbs front
26.5 lbs rear
That's pretty light for 19" OEM wheels from BMW
