I recently had a gunshot blowout on a brand spankin' new Mavic Open Pro rim. Either tire wasn't seated properly, or tube was pinched (though I'm always very careful about inspecting these things).
At any rate, I +1 the BS. Those shop mechanics/sales staff are thinking of old straight walled (no hook) rims.
