Why is the steering wheel vibrating in my Audi A4?

I recently noticed that my Audi A4's steering wheel is vibrating while driving, especially at high speeds. What could be causing this and how can I fix it?

The most likely cause of the steering wheel vibration is an unbalanced tire. This can be fixed by getting your tires balanced at a mechanic or tire shop.

Another possible cause could be worn out suspension components. It is important to get your suspension checked and repaired if necessary, as it affects the handling and safety of your vehicle.
