How often should I change the tires on my Audi A4?

I recently purchased an Audi A4 and I'm wondering how often the tires should be changed for optimal performance and safety. What are some signs that it's time to replace the tires?

It is generally recommended to change your tires every 3-5 years, depending on your driving habits and road conditions. However, it's important to regularly check the tread depth and inspect the tires for any signs of wear and tear.

One indicator that it's time to change your tires is if the tread depth is less than 4/32 of an inch. You can also look for cracks or bulges in the sidewall and uneven wear patterns.
