Just swapped off the winter tires for my summers. Rears are pretty new. I noticed that the back left hardly looks worn (full tread across the whole width - second photo below). But the back right has a narrow 'bald spot' near the inner edge (bottom of the first photo). It's only taken off the sipes which I guess aren't that deep, tread itself is still there. But struck me as a bit odd

Might it suggest rear alignment is a bit out? Doesn't seem enough to be too concerned with. Tires are all at recommended pressures.

Strange. I got the same error. Tried again to repost. See if that works
