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).
Every US car built since 2003 carries this placard. It also gives the pressures, which the sidewall does not: the number molded into the tire is the maximum it can hold, not what your car wants.
