when proper fitment and calibration is at issue, it would be better to use more
specific details such as the wheel model number being considered. though the
wheels from S220 or w140 may physically fit when attached to your car, they
may not perform properly. you should post the size of tire as well...or, once
the specific wheel has been identified, we can try to help with proper tire sizing
with an eye on compatibility with odo/speedo/cruise
