How do I properly deflate a tire on my Audi A5?

I need to deflate my tire slightly for optimal performance on a race track. What is the best way to do this without causing damage or making the tire too flat?

To properly deflate a tire on your Audi A5, use a tire pressure gauge to check the current pressure. Then, use a tire deflator tool to gradually release air from the tire until you reach the desired pressure.

Make sure to only release small amounts of air at a time to avoid damaging the tire. It's also a good idea to have a tire inflator on hand in case you accidentally release too much air.
