Answer
Rafat,

According to Tire Guides, Mercedes C240's came with 205/55R16's, so I don't think this is a problem.  But please check the placard on your vehicle to be sure.  Placards are usually located on the doorpost or in the glove box.

Plus, if this is a 4matic model, all tires have to be the same size, so it is important that they be changed in sets of 4.  Failure to do so may result in drivetrain damage - very expensive to fix.
