What Mercedes-Benz approves
MO is the Mercedes approval, MOE is the run-flat version and MO1 is reserved for AMG models.
Mercedes tunes the tire to the car's suspension and electronic aids, so an MO tire on a Mercedes usually rides closer to how the car left the factory. MOE tires have a reinforced sidewall and only belong on a car built for them.
Brands that carry the approval
Written on the sidewall as: Continental ProContact (MO), Michelin Pilot Sport 4 (MO1).
The drawing carries the sizes we list for this car, so you know what you are looking for. The placard on the car is still the final word, and it is the only place that gives the cold pressures: the number molded into the sidewall is the maximum the tire can hold, not what your car wants.
