Hi, I have a 2014 640i with OEM tires and I was coming through a drive through at a restaurant and I did not see there was a little corner hidden and chipped off the sidewall tire. I didn't immediately check the tire out till I get back home and I didn't feel anything wrong with the car as I drove it on the highway. I attached pictures. It's a bit rainy today so that's why there is a water drip on the tire. I'm so mad at myself for letting this happen as I'm usually careful and I just got both my back tires replaced this past summer.
