The car is a 2014 Honda Accord LX. It has no adjustable camber in the rear without aftermarket parts. I've noticed additional wear on the outside of my tires. It seems that the Accords are leaving the factory with negative camber pretty regularly, but I am unsure what is considered safe for tire wear considering the lack of adjustability. I saw one person who did end up buying a camber adjustment kit ended up removing it because the bushings were too soft.
