Once you have a tire pressure gauge, just follow these steps to check your tire pressure:
Remove the cap on the air valve
Press the tire gauge to the valve stem
Read the air pressure gauge
Compare the number to the recommended tire pressure found on the driver’s door jam sticker
Your tire pressure should read between 32 and 36 psi depending on your Audi A5’s trim level and wheels. However, the exact tire pressure for your model can be found on the driver’s door jam sticker or your owner’s manual.
If your tire pressure reads below the recommended psi, you’ll need to go to a gas station and use the air compressor to inflate your tires to the recommended pressure.
