Tires massively unevenly driven and damaged – cause?

Hello together, with my Audi A4 B8 3.0 TDI new tyres are waiting for the summer. During the dismantling I noticed that the tyres were extremely uneven – and sometimes even torn down! (see pictures). I was aware that the tyres are quite down, but I noticed the massive damage only when changing because the damage on the inside is noticeable. What could be the cause here? Fa Is there an adjustment of track and fall or is there even more behind it? I’m actually rather comfortable, clearly you take off from time to time a curve more sporty but the tires were not heated. With the new one I definitely have the chassis adjusted. For further ideas I am grateful! Greetings, Percy
