Strange tyre defect

Hello, Post the whole thing here again, because in my opinion (so I hope) it is not a vehicle-specific problem. I installed my winter tyres yesterday and I noticed a damage on the right front tire which gives me something to think about. Never seen this before and when I imagine that I drove with the car before 24h with over 200km/h over the down I get stomach pain. All other tires look perfectly except for minimal sawing. The tyre is like pressed in, has in one place also a crack BUT the thing does not pull around the whole tire but only 7/8. Should you be able to see well in the pictures. There was actually nothing run over or something like that, he drove himself also quite normal. Tires have come fresh 3 months ago on the rims, looked when they arrived perfectly. I would be interested whether someone has seen something like this or has an idea from where. owhat comes. The whole looks kind of dangerous to me and I want to avoid that repeating itself.
