I posted a reply to this, but it never appeared. It's still on my list of
posts in black. I'll try again.
If you're wearing on the inside of one front tire and the outside of
another, it's not a toe issue. I'd check the tie rod ends for looseness
to be safe, but I doubt you'll find anything.
Gather your printouts from the alignments. Use the one from the most
recent if you have it. Usually they will have the readings and
specifications on them. Pay particular attention to your front camber.
Camber isn't adjustable on your car, but camber too negative on one side
and too positive on the other can cause the issue you describe. Also
check your rear toe and thrust angle if you can. If your rear tires both
point to the right (excessive positive toe on L/R and excessive negative
toe on R/R, but not necessarily out of spec for total toe), then you may
have your front wheels perpetually turned right for the car to continue
straight ahead. I don't have much technical expertise with the more
complicated alignment issues, but I think in theory what I said about the
rear toe could possibly cause the condition you have. If there's someone
here with more expertise in alignments, perhaps they'll chime in. In any
event, if you have any of these issues, something is bent.
