That's not the usual failure. The tire carcass itself heats due to excessive flexure, weakens, and the (modest) air pressure that is there blows out the side. The candle analogy is apt. The rubber at the flame weakens, the pressure inside the balloon doesn't change much. If it did the balloon would increase in diameter noticeably before popping. It doesn't.
