The inside of the passenger front tire on my Tahoe is wearing badly. What would cause this? All my other tires are wearing normally. My oil change facility said it is simply the alignment. Are there any other causes of uneven tire wear on 1 tire only?
If it's just the inside of the contact patch, it would sound like the camber is off, either by a loose/broken/worn strut or mount/bearing assembly or ball joint failure.
