The only time I had that problem with a rear tire, I needed a four wheel alignment with shims. I didn’t believe the tire shop when they said it was pulled out of alignment on the transport truck when it was delivered new. I wore a rear tire out to near octagon shape in less than 30K and finally let them do a four wheel alignment. That did the trick. A dragging brake or bad bearing wouldn’t wear the tire a tire out but a mis-aligned tire could cause a dragging noise. Maybe better go to a good alignment shop.
