Tires damaged when parked?

Hello together, I parked yesterday (slowly and gently), but came with the right back to the curb, what I looked at the tire afterwards (that happened to me years ago). Now I actually discovered a notch. It can be good that it was already in there before. I bought the car in the summer and the winter tires were there. Since I had it done only a week ago, it could have been in there before. Anyway, Ic h once attached two photos. My question would only be if I should change the tire. Probably nobody came here to make a binding statement. I drive to the workshop again next week to screw. There they should look at this again. Thanks and greetings, Hansi
