Indeed, on-the-road blow-offs tend to happen after extended braking.

I've twice had tires blow off of Araya rims while riding. Two different tires (one 23mm Trex/Matrix wired, one Schwinn/Panaracer Circuit folding) on two different rims (both narrow, one red-label 700c and one a CTL-370).

Both instances were on the front wheel, running 95psi. One occurred after descending Page Mill road, the hairpin right hander at the very bottom after bearing right at the Y intersection (no longer on Page Mill road, I guess). The other occurrance was coming into Glendale from the south if I recall. There's straight and steep descent there. Both loud blow-offs were preceded by several wheel revolutions of tire thumping against fork leg!

One other blow-off occurred in my livingroom. Narrow, gold Araya with a cheap, folding Michelin (Select?). I heard a noise and found about 8" of the bead atop the rim's edge. I was able to deflate before the tube escaped!
