Hi. Just noticed on my mom's Edge (a 2007 AWD) that one of the rear tires (can't rememebr at the moment if it's the driver or pass. side. lol. It's is wearing on the outer side. All other tires look fine, just this one. She recently ('bout a month ago) had it in for tie rods, brakes, and allignment. Tires overall have about 60% tread. I believe they're hankooks. And they were rotated. I'm just starting to look into this before I have her bring it in to our mechanic, to see what you all might think. I'm not too familiar with rear tire outer wear. Maybe suspension? Anyway, I usually notice things out of place, and I didn't notice this until today, which makes me pretty sure it's not from another spot before rotation. If it were, say, the rear passenger side, what would be some possible causes? Thanks in advance. I always like to find out all my options before taking action.
