How do I know if my Audi's tire pressure is too low?

I recently got a new Audi and I want to make sure its tire pressure is always at the right level. What signs should I look for to determine if my tire pressure is too low?

Low tire pressure can affect your car's handling, fuel efficiency, and overall performance. To check your tire pressure, use a pressure gauge and compare it to your car's recommended tire pressure. If the pressure is significantly lower, you may have a leak.
