Yep that tire is not long for this world. I agree with Mooney, unbalanced or forks misaligned or maybe a faulty tire to begin with. Certainly more wear than the crown of the road or more left hand turns as some say would do. I do not recommend doing this but the wheel can be flipped and see if it starts wearing the other side. I ran that way for several hundred miles once before noticing I was backwards and did not appear to suffer any negative consequences. I have read about a wheel needing to be balanced across from side to side also if not even. I have seen shops put weights on the center line and sometimes stuck to one side more. Not sure how it really should be. I have had side wear before and just got a new tire ASAP. If it happens again with new tire suspect the bike other wise the tire.
