I've had two instances when it wasn't.
1) Hit half a glass bottle in the rain/dark when going down a hill
2) Hit sharp strip of metal that flipped right into tire
In both cases, the tire was instantly destroyed. Basically, if you hit anything long and sharp enough -- the most likely case being a portion of a broken bottle.
But yes, even nails and screws through the sidewall should only leave a hole, not a giant rip.
