Dad has a '96 Mercedes C280. Last year, we bought him a set of snow tires and a used set of factory alloys to mount them on. Sadly, the wheels were off of a '95 C-class and don't clear the rotors on the '96. It's been suggested that a set of wheel spacers would resolve that problem. I don't have any experience using spacers, and the concept makes me just a bit nervous - anybody out there have experiences or opinions either way about whether or not they are a good idea?

Thanks much!
