What size wheel does the Audi A8's adaptive air suspension system use?

I am planning to upgrade the wheels on my Audi A8 and was wondering what size wheel would work best with the car's adaptive air suspension system. Would larger or smaller wheels affect the performance of the suspension system?

The Audi A8's adaptive air suspension system can accommodate wheel sizes ranging from 18 to 22 inches. However, keep in mind that larger wheels will result in a stiffer ride, while smaller wheels can provide better handling and a smoother ride. It's important to find the right balance based on your personal preferences and driving habits.
