Macke in summer tire 205 / 55 R16 91V Michelin Pilot PRIMACY

Hello everyone, I got a set of summer tyres for my used Audi A3 when I bought it. You could drive the tyres one more summer, although they are already a bit down. Only a tire has a Macke (probably from parking) Can you have something like this put on or is it too dangerous? The Macke goes about 4mm in the tires. As I said: Summer tire 205 / 55 R16 91V Michelin Pilot PRIMACY Here are pictures: picture 1 picture 2 picture 3 picture 4 Thank you in advance for your Reply. Greetings Jockbert
