I picked up my new 70D at the end of September, and today while getting the car detailed and opti-coated the detailer pointed out a crack in one of the wheels. I'm not losing any air, but aside from that I don't know of any way to tell if this is structural or just a paint issue. Haven't hit any large potholes or curbs. I'm not one to make a big stink over something cosmetic in a very un-noticeable place, but obviously concerned if this were a safety issue. Looking for opinions.
