Yup, I'm a wheel nut. Minimum 18" and maximum 19" wheels for the SLK. Depending on brand and style, they sometimes dictate whether you can get 18" or 19" wheels. I believe Doug is referring to the TireRack.com. They have many wheels available and you see what they look like on the SLK. Check the picture threads in the various forums for what others have gone with. Almost everyone has a suggestion or a preference. GET WHAT YOU LIKE.
