What causes a loud humming noise in the Audi 80?

I've noticed a loud humming noise coming from my Audi 80 when driving at high speeds. What could be causing this and how can I fix it?

The most common cause of a loud humming noise in an Audi 80 is worn out wheel bearings. It's important to get this fixed as soon as possible to avoid further damage to your vehicle. I would recommend taking your car to a certified mechanic for a proper diagnosis and repair.

Another possible cause of the loud humming noise could be a problem with the tires. Check the tread on your tires and make sure they are properly inflated. It could also be a sign of a misaligned or unbalanced tire. I suggest getting your tires checked by a professional to determine the issue.
