I just got new HRE P101s (21") put on my MS! This is a new wheel from HRE (101 in mono block). They've only shipped a few sets of this wheel for any car (they just came out) and mine is the first Tesla. However (and I found this interesting), Tesla Motors ordered a set apparently for test purposes.
These wheels save 50 POUNDS off the car's weight. They are very light and I'm sure will increase range.
