What Audi approves

Audi

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

Michelin Continental Pirelli Hankook Goodyear

Written on the sidewall as: Continental SportContact (AO), Pirelli P Zero (RO1).
