I should mention that the 700 x 28 wire bead that blew off the rim was on an Alex rim, if memory serves. I have 700 x 28 wire beads tires on Campy rims with no problems (so far anyway). When the tire blew off the rim it was a few minutes after mounting the tire in the living room, and not while riding. Also, I don not believe that it was sloppy mounting technique that caused the tire to unseat.
