my front right tyre i worn a lot on the shoulder. It was a used tire replacement with similar wear but not from same set. Same model though. Thread may be 0.5mm difference. Doubt it's that, but shoulder is worn outside. I heard once tire starts getting eaten up, it will keep on going regardless of alignment changes.
