Load Identification - Mercedes-Benz 2008 S550 Operator's Manual

Any tire with a speed capability above
186 mph (300 km/h) must include a
"ZR" in the size designation AND the
service description must be placed in
parenthesis.

The "(Y)" speed rating in parenthesis
designates the maximum speed capa-
