How to check for tire wear on a Audi A4?

I just got an Audi A4 and want to keep it in top condition. I noticed some wear on the tires and want to know how to properly check and maintain them.

First, check the tread depth with a penny. Place it between the treads, and if you can see all of Lincoln's head, it's time for new tires. Also, make sure to rotate your tires every 5,000-7,000 miles to prolong their lifespan.

Regularly inspect your tires for any signs of uneven wear, such as cupping or feathering. This could be a sign of alignment issues or under/over-inflated tires.

Another way to check for tire wear is to run your hand over the surface of the tire. If you feel any bumps or flat spots, it's time for new ones. Remember to also check the sidewalls for any cracks or bulges.
