Probably not, but I wouldn't expect bearing wear on a 2015 with 10k miles either. It could happen, though.
Wear on the outer edges typically means the tires are slanted in at the bottom, like this: \ / so that they wear on the outer edges. More often it's the inner edges that do this, which would mean an axle bent down from overload or a bad bump, but an axle bent the opposite way wears the outer edges. In either case, that is a wheel camber problem. However, it is conceivable that the tires are slanted by toe-in rather than camber. Not common on a fixed axle like that, but not quite impossible either.
