Tyre profile TÜV/Inspection!

Hello, I have a question regarding TÜV/Inspection. Isn’t the tyre profile usually checked? I’m pretty upset, because at the TÜV and the annual inspection almost 4 weeks ago (cars were not used 14 days because of holidays and holidays) it was not seen that my front tyres (winter tyres) on the passenger side were about 3 cm and driver side outside about 1.5 cm bare. This was noticed yesterday by the tyre futzi when he started the new summer riding. According to him, this should have been noticed directly by the TÜV tester if he had taken a look at the tyres! Also the car workshop, which made the annual inspection, did not point out to me that if possible the track could be turned off, especially since the mechanic still said that I still raised the winter tyres. According to the tire man, the unequal wear did not arise in such a short time! I always have 300 Euronen for TÜV un The inspection is in progress!
