How to maintain optimal tire pressure in an Audi A5?

I recently purchased an Audi A5 and I want to make sure I am properly maintaining the tire pressure. How often should I check the tire pressure and what is the recommended pressure for the Audi A5? Also, is it better to overinflate or underinflate the tires for different driving conditions?

It is recommended to check your tire pressure at least once a month. As for the recommended tire pressure for the Audi A5, it varies depending on the model and trim. You can find this information in the owner's manual or on the sticker inside the driver's side door jamb. In terms of overinflating or underinflating, it's best to stick with the recommended pressure for normal driving conditions. However, if you are driving in extreme weather or on rough terrain, you can adjust the pressure accordingly.
