There are speed sensors on each wheel. As previously posted, just match the overall diameter of the original tires. Any tire shop worth dealing with can do this for you in a matter of minutes. Have you checked out the Tire Rack's fitment page on their website?neilbo75 said:Does anyone know if the speedometer sensor on a 2002 (w208) CLK 55 AMG is on the front or rear axle ?
I am thinking of increasing the diameter of the rear wheels, by either increasing the rim size to 18 inches or by increasing the profile. I am concerned that this will affect the speedometer. Will it ?
Might other systems like ESP also be affected ?
