I noticed today that the tires on my dad's car are... flaking for lack of a better term on the shoulders.

I can't get a picture right now, but there are quite literally flakes of rubber in various stages of falling off. The rest of the tire looks fine, it's fairly new time-wise, not at the wear bars, etc...

My best guess is that where he parks requires a lot of lock-to-lock without rolling forward or backward. Could that be enough to tear up the outer edge so badly?
