I wiped the wheels off a good while back but other than that the wheels have never been cleaned since new and that is 7200 miles.
Also of note is that I took 3 pictures in about 10 seconds with my iPhone and they may or may not be the best of quality.
I have dropped a trailer tire off of a curb before but not this one.
Here is the third picture that I took from about 30 inches away. As you can see it gives a completely different look to the flaw. Also of note is that when I got it to the storage lot I could not find the flaw again. But, I know it is there.

I still vote for rim pinch. This happens when the tire over-deflects when hitting the exit side of the pothole and the tread bottoms out on the rim. The lower sidewall
Here are three pictures of a more extreme hit.
In this case the rim was clearly bent and the body cord snapped and broken. I have inspected many dozen such tires that show everything from marks with no obvious external damage to tires that were cut completely through the sidewall but with little apparent damage to the rim. The infinite variations of speed, tire size, load, inflation and shape and size of the object or hole that were hit all affecting the end condition.
This shows that Forensic Tire Inspection is not a simple act but involves years of experience.
I guess I need to do a few more blog posts on tire inspection basics.
Hope this helps.
