These wheels came from a 2008 Mercedes S550 and are the sought after AMG wheels that were an added option for the car. You can probably find what else they fit from looking at an ebay add that gives that information. As to the wheel sizes and part numbers here is what is on the inside of each rim.
The two rears are 9 1/2x19 with ET43. Part no A show contact info
and,
the two fronts are 8 1/2x19 with ET43 & Part no A show contact info
.
The condition varies with the first 9 1/2 wheel shown in the first photo has probably not been used while the other 3 have been and their condition can be seen in the photos. All are true.
I will consider selling any of the wheels and tires as a pair. NOTE the TPS and the center caps are no longer available.
