The car in question was lowered and was running the tires underinflated.
Having done the most experimenting possible with Kumho's, I have come to the
conclusion that the crack comes from underinflation and overheating.

Having done the most experimenting possible with Kumho's, I have come to the
conclusion that the crack comes from underinflation and overheating. While
it was raining at this event, if the crack was there prior to the event (and
the spin), the tire could come apart. Not to mention that the surface at
this site is like a cheese grater.
