What Audi approves
AO marks an Audi approval, RO1 an approval for the RS models.
Audi's approval covers noise and rolling resistance as well as grip, which is why an AO tire is often quieter on an Audi than the same model without the marking. RO1 tires are built for the higher loads of an RS car.
Brands that carry the approval
Written on the sidewall as: Continental SportContact (AO), Pirelli P Zero (RO1).
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.
