Further to tribo's post:
http://www.dunlopaircrafttyres.com/t...172/DM1172.pdf contains excellent information (a lot of which I'd forgotten)
and this, from Trans Technical Services Co Inc:
WHAT HAPPENS WHEN A TIRE EXPLODES? Air Safety Week
had an interesting article on the energy released by exploding tires in their August
7, 2000 issue. It was addressing the tire failure on the Concorde. If you go to page
3 (of that issue) you will find a chart − Energy Released by Catastrophic Tire
Deflations. If you “used the same numbers” for a P-3 (Navy aircraft) main
landing gear tire at 200 pounds per square inch (psi) tire pressure to approximate
the energy released by a 747 main landing gear tire failure (194 psi) − it would be
301,071 foot pounds . . . . equal to 0.60 sticks of dynamite. If the tire burst at
the maximum pressure of 1,170 psi it would release 1,215,789 foot pounds of
energy − an amount equal to 4.4 sticks of dynamite.
