haven't seen this posted before. idiots on the website said it was just a tire and the air pressure made it do that, but that's gotta be tannerite.

Tannerite is an explosive that is designed to be detonated by the impact of a rifle bullet. It's shipped as two separate bottles of different compounds which, individually, are not explosive. When the two compounds are mixed, they become an "official" explosive.

Wow that looks like fun!!! I don't think those guys would have been laughing if that piece was little more to the left.

Someone shot some at BulletFest last year and it was next to an old washing machine. It sent the metal lid half way to the firing line, the RO's were pretty upset lol.

yep... tannerite is pretty fun stuff.

Shooting Tannerite is quite safe when the Tannerite is just all by itself in the provided plastic bottle. It's when you start attaching the Tannerite to other things and then shooting it that you get the possibility for shrapnel. If you shoot multiple bottles at once and use it to blow other things up, well....

Guys, if that's a tractor tire, as the idiot in the vid indicates, and they aired it up high you could expect an explosion. This isn't like your car tire. There's an amazing amount of energy in a big tire. As a safety professional I've got an entire file of horrible images of guys blown apart that were too close to tires on tractors and construction equipement and aircraft when they blew.

The pressure wave propagated awfully fast for it to be just an over-pressured tire. But there was no residial fireball or smoke, so most low-order explosives are out.

Have to give this one some thought...

hso can you tell more, about the tires blowing? Causes, and effects?

It didn't sound like Tannerite. Even at a fair distance, it's way louder than the report from a centerfire rifle.

And I was thinking the same thing, that some tractor and truck tires can fail explosively. Several mechanics have been maimed or killed by exploding high-pressure commercial tires. There are even special safety cages that cover truck tires when they're being worked on to contain the larger fragments if a rim fails.

Although I have seen internet videos where several bottles of Tannerite were placed in a junker car at a regional shoot for that particular board. The car was at 100 yards, and the hood landed behind the firing line.

I am willing to bet it's Tannerite. I've shot alot of those and they explode so fast you literally hear the report of the rifle and the thing explodes almost together. I've read about (Cant say for sure if its true) some test's done with Tannerite and it explodes before the bullet has even passed through the container its in. They call it a low explosive but damn, that stuff can really blow crap up.

may have had something like fixa flat in it, that stuff is highly explosive.

How is it that Tannerite is NFA legal? Low detonation wave velocity?

Large tires found on big rigs or aircraft can be dangerous. In AF tech school for aircraft maintenance they have very graphic photos of what happens when acft wheel/tires fail. One in particular that stuck with me was of a crew chief that used a hi-pressure line (3000 psi) to inflate the main landing gear tire on an F-15. The wheel split in two and sliced the poor guy in half. While servicing tires on the B-52 we had to stand in-line with tire and use a 12' servicing hose to the tire. A pair of goggles would protect us from the explosion of a 56x18, 38 ply tire inflated to 305 psi. However the wheel and tire shop does have safety cages for building up and tearing down.

Even low pressure car tires can generate some force. I've born witness to an inflated tire off a VW being chucked into a bonfire, and it's something you wouldn't want to stand next to!

Be careful with your Tannerite

Gotta love it. The thread is posted with a warning about tannerite, but the example is of a tire exploding for which the orignal poster didn't think could be the result of tire pressure alone. Having ruled out tire pressure, he deduced it must be tannerite, as if that was the only other option possible, which it isn't.

They call it a low explosive but damn, that stuff can really blow crap up.

Then there are assumptions like this that it must be tannerite because tannerite explodes so fast that the report of the rifle and the report of the tannerite almost occur together. Of course, whether the report of the rifle and the tannerite occur close together or not is a product of distance. The sound from a tannerite explosion is not going to be traveling faster than the speed of sound.

For those doubting the explosion could be from a tire along, I suggest you consider pyrolysis

Note that exploding tires have been attributed to bringing down various aircraft when the explosion of the tire occurs inside the plane in flight or occurs on landing with enough force to cripple the landing gear that then collapses.

i have shot tannerite before, and to me that looks like tannerite. if i'm wrong, i apoligize.

Anyone know whats in that stuff (tannerite) anyways???

It can't be too complex but curiosity has always made me wonder whats in there.

thanks to anyone that has an idea.

Inflate a defective wheel/tire or over inflate one in good conditon and you have a pressure vessle on the verge of detonation. They guys who have mentioned cages are correct and the Air Force image is one in my files.
