To be strictly accurate, the tank was not punctured by tyre debris, it was burst from within by hydraulic/hydrostatic shock. The tyre debris hit the underside of the tank, and set up a shock wave inside the tank, which 'bounced back' and caused a rupture. This rupture from within 'blew out' a much larger piece of tank than a penetrative hole might have caused. This is why it is interesting to ask whether a less full tank have burst in the same way?
