What causes uneven tire wear in an Audi 80?

I've noticed that one of my Audi 80 tires has worn down much faster than the others. What could be causing this and how can I fix it?

This could be due to improper alignment, which can lead to uneven pressure on the tires. Make sure to have your alignment checked regularly to prevent this issue.

Another possible cause could be worn out suspension components, which can also lead to uneven tire wear. Have a mechanic inspect your suspension for any issues.
