You'd need pretty high speeds and a pretty decent sideways force from the
roadway - tough to do that unless you were fishtailing. Are you sure you
didn't nick it or pinch it on something first?

The tube didn't have any other hole besides the monster rip from the
explosion. I was leaning in like on a motorcycle so I could pedal, and I
did with some force... plus I had cornered all the way from the inside to
the outside, and on the outside where the rolloff occured the lean angle
compared to the street was even greater because the street slopes quite a
bit from either side to the middle. I didn't do any skiing until after the
blowout. This was my first time to take this graveyard course. I'm
thinking of holding a Crit there... if this happens again I'll have an open
grave for the fall so we can be more efficient. Spacey

I once rode (briefly) a tyre/rim combination that was so poor that the
tyre kept on pulling away from the rim. I noticed the lump in the wheel
and managed to stop and deflate the tube before it popped, but a section
of the tube was quite clearly exposed and would presumably have popped
had it been thinner/higher pressure. This happened a couple of times, I
ended up riding home slowly at about 40psi and never used that
combination again (mainly the rims to blame that time, I believe). I
don't think I needed to corner hard to generate the problem but it seems
likely that it would make the tyre more likely to disengage.
