The wheels I am looking at are as per your offset and tyre sizesIf you are fitting 19" alloys to a W204? (2007 -14) ensure they are the correct ET (offset)
Fronts should be ET45, rears ET54.
The tyre size you need is 225x35x19 fronts and 255x30x19 rears.
Double check fronts... mine were 235/35R19....
Ah, but you had a C63 not a C220Cdi
