How to check and maintain proper tire pressure in an Audi 80?

I recently purchased a used Audi 80 and I want to make sure I am properly maintaining the tire pressure for optimal performance and safety. Can anyone provide step-by-step instructions on how to check and maintain the tire pressure?

To check tire pressure in an Audi 80, first make sure the car is parked on a level surface. Remove the valve cap from the tire valve stem and use a tire pressure gauge to measure the pressure. Compare it to the recommended pressure in the owner's manual. If necessary, use an air compressor to fill the tire. Regularly check and adjust the tire pressure to ensure optimal performance and safety.
