I just got new wheels on my 04 X5 4.4i
These are new wheels from X6 M version I believe.
The visual is 1000x better then my stock wheels and handling have improved alot and the ride is very stable. I am very happy with this set.

Tires are Toyo Proxes ST II 275.40.20 Front/315.35.20 Rear

Here are some photos from my iphone.
