How do I maintain optimal tire pressure in my Audi A3?

I recently purchased a Audi A3 and want to make sure I am properly maintaining the tire pressure. Can someone provide me with tips or guidelines on how to maintain optimal tire pressure?

It's recommended to check the tire pressure at least once a month and before long trips. The optimal tire pressure can usually be found on the driver's side door jamb or in the owner's manual. Make sure to use a good-quality pressure gauge for accurate readings.

Maintaining optimal tire pressure not only helps with fuel efficiency, but also ensures longer tire life. Make sure to check the tire pressure when the tires are cold, as driving can affect the pressure readings. Refer to the owner's manual for the recommended pressure range.
