Wheel Doctor

Hello, my 996er has now 70,000km down and there are no damage to the rims. Yesterday I underestimated the entrance to Cinemaxx and swooped a fat macke into the left rear rim. Also the coat of the tire got a damage. As far as I can estimate this as layman I would say nothing dangerous, stop 1-2 mm deep scratch. With us in the area (Braunschweig) I find unfortunately no professional rim doctor. Is this at all advisable? Verlie I don’t want a tire to burst at 300km/h or a rim to break… Would you trust your darling, for example, http://www.autojuwelier.de? Does the Porsche workshop make rim repairs? Greetings
