Billed for Someone elses damage

Avis gave me a Faulty car, now they are billing me for that fault because they did not do their inspection properly. It was my first time hiring a car I trusted them to inspect the car with due diligence. I was given a car with a faulty tyre but the tyre was not showing at eye value, I saw the tyre pressure light and I though maybe the car has sensor issues and since they gave it to me like that possibilities are they know the issue. I continued with life only to find out that I will be billed for a damaged caused by their previous customer and they did not pick it up.
