Recently had a sidewall failure on a Continental 700 x 28 Gatorskin tire.
Mounted once and only once on a Weiman Concave rim it blew at less than 350
miles. The sidewall suffered an inch and a quarter "cut" right next to the
wire bead. The tire material surrounded the inside of the bead but the bead
could be observed from the tire side.

Check for worn brake pads contacting sidewall. If that sounds like a
novice mistake, well, I've been there and done that (long after I should
have known better).

In my case, the pads, either initially or as they wore, reached slightly
above the top of the rim. Wear then caused them to overhang the rim
with a very thin (i.e. knife edge) shape, and two tires went quickly
before I figured it out with much embarassment.
