What causes a car to shake while driving?

I recently noticed that my Audi 80 starts shaking when I reach a certain speed on the highway. What could be causing this issue and how can I fix it?

There could be several reasons for your car to shake while driving. It could be due to worn out tires, misaligned wheels, or even a problem with the suspension system.

One of the most common causes of shaking while driving is an unbalanced tire. Make sure to get your tires balanced and rotated regularly to avoid this issue.
