How to maintain optimal tire pressure in the Audi A8?

I recently purchased an Audi A8 and I'm wondering how often I should check and adjust the tire pressure for optimal performance and fuel efficiency?

It's recommended to check the tire pressure at least once a month, and always before long road trips. You can find the recommended tire pressure for your A8 in the owner's manual or on a sticker located on the driver's side door frame.

Always make sure to check the tire pressure when the tires are cold, as driving can increase the pressure and give you an inaccurate reading.
