Tire damage due to crack: Still mobile on highway?

Hello forum, in preparation for a longer motorway ride I had to find a crack on the right front tire. It should have happened by a ride against a Kantstein o.Ä. Now I have read in forums that it is decided whether one can see fabric or not. I can see no tissue and the crack seems to me to be only superficial. Can I still drive on the highway with it? Since the car will be fully loaded (4 people + luggage) I wanted to drive anyway only 100-120 kmh . Pictures in the appendix. Thank you very much for the answers.
