many mercedes use 12 mm wheel mounting  bolts....
but the hole in the wheel is big enough to take a 14 mm stud or bolt.
or sometimes with the tiniest bit of enlarging the hole in the wheel where
the wheel mounting bolt goes.
  9/16's inch drill with a half inch shank is handy for that.
  I see some of the Benz's use 14 mm wheel mounting bolts or studs......so
no problem there.
it's the ET that you need to know and get about right, or adapt to correct.
