I have to disagree. I work in the tire industry. The failures I'm talking about are not from sidewall impact, but from scrubbing the curb, which is virtually identical to grinding on the sidewall. The white inner layer actually will peel off the inner black layer. As stated, there's a reason that they overlay the white layer with the black. Messing with sidewall integrity is not something to take lightly. Especially when you keep in mind just how thin the sidewall is on a modern tire, especially passnenger car tires. You have maybe 1/4" of rubber on a quality tire, less on cheap ones.
With all of the recent issue with tire safety, would you really want to risk it?
