I can only conclude that the wheel pictured as the 640M is the 19" wheel.
Further, only going by "feel", the wheel pictured as the 640M looks more like a 19" one and the one picture as the 641M looks more like a 18" one (I know, very subjective  )
Can you shed some light 
Thanks  |
Yea... I also suspect that the 640M is the 19" wheel. I think its a technical typo from within BMW. See the picture I have posted is not really suppose to be released to the public. Normally BMW checks and double checks technical things like the wheel images to part numbers - when they are ready to release the ordering info. That has not happened - yet. So I think in time... we will know for sure.
