CHays, follow the power of M ... Mercedes, Mobil 1 and Michelin. Check your Owner's Manual for the speed rating of the recommended tires because that determines the stiffness of the sidewall, which affects ride & handling. Best to go with the specific tire characteristics specified by the design engineers.

A 205/60R15 tire will fit your car and will provide a more aggressive look without affecting the speedometer reading. That is the tire size I run on our MB vehicles that originally came with 195/65R15 tires. Gas mileage may drop slightly. Going with a wider tire may interfere with suspension components.
