What causes the Audi A8's steering wheel to vibrate when driving at high speeds?

I've noticed that my Audi A8's steering wheel starts to vibrate when I reach speeds of 80mph or higher. It's not severe, but it's definitely noticeable. What could be causing this and is it something I should be concerned about?

This type of vibration is usually caused by an out-of-balance tire. It may not seem like a big deal, but it can actually impact your car's handling and create excessive wear on your tires. It's best to get it looked at and fixed as soon as possible.

Another common cause of steering wheel vibration in Audis is worn or damaged suspension components. If your car is older or has high mileage, it's possible that the shocks, struts, or other suspension parts may need to be replaced.
