Maybe I did, I dunno. The tire didn't have
that many miles on it, at most 1500. And this was a 305 gram Roubaix, not some PR3 or anything. It could have been worn in a particular spot, however, so your scenario is quite plausible. There was no warning whatsoever, however. I'd think that a casing defect herniating a tube would have been noticeable immediately prior to rupture. It was a bolt from the blue.
