We installed blue Alloygator wheel protectors on this black Mercedes C300. This car has the standard 17" wheels. The wheel protectors add a nice accent to this car that helps it stand out while offering excellent protection from curbage. There is no issue installing on these Pirelli run flat tires. The local Mercedes dealer offers these wheel protectors as well, but with an hourly rate of $200 an hour, they were asking close to $400 installed.
