Seven Spoke Composite
These are the wheels found on the 540i with the Sport package. The Sport package also adds Motorsport tunings to the suspension and interior. (It's not actually an M wheel, but the 540iSport was the closest thing to an M5 until recently...)
E-39 M5
These are the standard wheels on the new E-39 M5. They are alloy finished in a satin chrome.
M Contour
The M Contour wheel was an optional design for the E-36 M3. They were normally found on decked out luxury packaged M3s, or on M3 sedans. M Wheels page 2
