I wonder what made the tire  explode?  And I wonder what he was just before it exploded.
Seems pretty scary.

I despise msn and their stupid commercials.

What the heck?   and what gave him warning that it was about to blow up?   Why did it blow up?

YIKES...that would be a killer for sure...

What the heck?   and what gave him warning that it was about to blow up?   Why did it blow up?

In the description under the video the wife says he heard a thud. This was in Brazil. I wonder if the tire sitting in the sun caused it to blow.

     In my younger days I worked at a truck stop. I worked in the shop for years and fixed a lot of semi tires. Eventually moved out of the shop and inside but would help out when needed. One especially busy day the boss told me to go out and give the shop guy a hand so out I went. The kid fixing tires was pretty new to it. I got out there and asked what he needed and he had me start airing up a tire he had just mounted up. There were a lot of split rims----even a few widow maker rims now and then----but this was an 11R24.5 (tubeless) so I did not put it in a tire cage. I had been fixing tires for over ten years and never gave it a second thought. I had the tire leaning against the tire dunk tank with about 95 psi in it when I knelt down to put a valve core in it when it went BANG. I remember a blast of air going up the front of me and blowing my ball cap off, the force blew me sideways 4 feet and under the trailer we were working on. I don't know how long I was out but as i kinda came to I panicked and tried to get up.  That wasn't happening. The tire had crushed my left knee cap, broke my femur cross ways and also split it 11" length wise and blew it outward. And I couldn't hear crap out of my left ear. Dam thing went off like a bomb, and people came running. Ended up with a nice titanium (I think) rod inside my femur with all the pins and screws that were included. Found out later the driver of the semi had a flat on the RFIT and was limping it in when the outside tire blew out on the same axle. He was almost to the truck stop so he limped it on in. In doing so he messed up the bead on that outside steel rim and told the kid to go ahead and put a tire on it, he could not afford a new rim. Like I said Ted was new and overwhelmed and did it. I just walked into a bad situation. That was about 35 years ago.  I bet the tire in that video had been run flat and had broken the cords in the sidewall. That guy probably heard it snap or popping and saw it bulging out the side and was smart enough to get out of the way. You saw how violent that thing went off. I have seen other tire explosions that are just as scary. Compressed air can kill. A year or so after this I was airing up a wheel barrow tire with a bicycle tire pump and that made me nervous. Had my head turned away and at arms length. Have since relaxed about tires and even fixed a few more before giving that kinda work up. Loud unexpected bangs tho still freak me out.   This picture had me laughing for days. If you have been around tire work, you know. I was doing it all wrong.

In mother Russia, Tire not go in cage. You go in cage.

I don't blame you for being skittish since that accident  That's crazy!  You are lucky it didn't take your face off, or worse. 

I saw a story about an air compressor tank blowing up (it might've been on here, don't remember) in someone's garage. Same type of explosive effect as in this tire video. Ever since then I get nervous when my compressor tank is filling up.  Maybe I will build a steel cage around it one day.

But yeah I don't get what made that tire blow up in the video.  The video has sound.  I don't hear a compressor running or see a hose attached to the tire.  Hard to believe the hot sun would make it do that.  Shrug.  Good thing they got out of there in time!

The cause was very simple and should be very obvious, especially to the guys that worked in a tire shop.
The tire was overinflated. Regardless of the tire or wheels condition which could have contributed as well.
As you can see in the video, nobody is watching to see how much air is being put in the tire. The air hose is just connected and then ignored. The air hose is supposed to have a manual operated regulator with gauge to prevent over inflation. The tire should not exceed the capacity of the tire which is on the side of the tire. Only the minimum air required to seat the bead should be used. The tires bead and the rims bead seat area must be clean and properly lubricated with a vegetable based lubricant only. Never a petroleum based.
The un monitored pressure would go as high as whatever the capacity of the air compressor was or until it failed.
Totally preventable and a great example of what not do when inflaing any sized tire. Just plain stupid people.

Where do you see an air hose?

[Filthy Filbert]

The video is a bit grainy but I don't see an air hose going to it.  I see what could be air hoses or extension cords on the ground in the gravel, but nothing that clearly looks like an air hose going to the wheel.

Also, I tried to watch frame by frame to see where the wheel went, and I can't find it.   Would like to know where it went!

Look at the post  next to the brick wall on the right, the rim will appear after the explosion. The force of the explosion would require a tire to be massively overinflated unless there was an explosive in it, which I doubt. The detail is not very good in this picture. He heard a noise, that would either be the rim starting to fail (looks like a 2 piece rim) or the tire s/w separating. The sun didn't do it. I was in the tire business for over 30 years and have seen many dumb things happen in that time form bicycle tires exploding to truck tire failures. Very exciting stuff.
Always preventable. There are safety procedures and people just ignore them.
Those should always be in a certified tire cage.. Brazil ??? I guess people are cheaper....

Ok, if you want to find the rim after the explosion. Stop the video at :42 . Get out a tape or ruler and working from the top right side, measure down 1 3/4" from the top and 3" from the right. You will see the rim center. Now go back before the explosion and look at that spot...no rim.

   I keep going over and over to. It is awful grainy but I still don't see an air hose hooked up. And that rim is gone. It looks like a dayton style rim to me. Trying to match it with the other tires still on the trailer but my eye sight is not that great anymore. I agree that over inflating a tire by that much is pure stupidity.    Just went over it again and changed my mind on the rim. It is probably more closer to the ones unmounted. Not sure what those are exactly.

[bentpshrods]

    All right. Morbid curiosity keeps me looking at this. I think that style rim is a what was commonly called a widow maker. I had only fixed one tire with that rim. My boss at the time was extremely familiar with them. He had one come apart on him and almost took his head with it. Fractured his skull so bad he had to have a steel plate permanently installed. Messed him up. He only let me do it because he knew the guy and to say I at least had done it. Pretty scary stuff. I was lucky they were being phased out at the time and the boss refused to deal with them.  Here's a video explaining these rims.

Wow.  Thanks for posting that info.  Very informational. I had no idea.
