Longbox 55,
I beg to differ. The very thin black rubber that covers the white lettering is not a structural part of the tire.
The failure you are talking about is a result of structural damage to the side wall due to an impact or multiple impacts... being "curbed" as you stated.
There are people that actually machine down the sidewall instead of grinding it as the guy did in the video. This had been done on thousands of tires with successful results.
