If anybody wants to see bigger tires done and has some laying around we are up for the challenge :D Next time probably with bottled nitrogen to save some time. I don't want to wait 8 hours on the bunker to tires to explode :D

This episode brings back bad memories of my first year as a mechanic. I was mounting large truck tires and nobody told me any of the safety rules, so after having mounted a few, using bars no machine, I was tired and was sitting on a tire while filling it. I didn't know that the rim was slightly warped, so it detonated at just over 100psi, sending me (250lbs) up about 4 feet and over 8 feet. The tire hit the shop wall about 30 feet away. I walked away from that with sand blasted eye balls and some bruising, I consider myself very fortunate.

The girly calendars on the shop wall truly create an authentic set production. Nice work.

That rug really ties the room together

I inflate 22.5" tires at work, I put it in a safety cage, use air regulated to 125 psi, and I walk away and work on things on the other side of the shop for about 15 minutes. This here is a great demonstration of why I do it this way.

What you should do is do this while the tires are on a vehicle and see what it does to the car/truck.

In 1971 my father was working in a tire shop on a set of split rim truck tires when on of them blue apart. He had not secured the locking ring properly. It tore 3 fingers off of hie left hand and broke 7 ribs. Two had multiple fractures. He also had severe bruising on the entire front of his body and lost the earlobe on his left ear. Somehow his hearing recovered and his eyes were not damaged. He was told by the insurance people he was one of the lucky 1 in ten that actually survive that kind of accident. Most people are bending over the tire assembly when they blow. He had stood up and was turning to walk away when all hell cut loose. Thanks for demonstrating the incredible raw power released when these things go wrong.

Rest in pieces tire guy, you were the best, and I realise the pressure finally got to you.

I got blown up by a rear backhoe tire when i was 19. My 2nd or 3rd near death experience. I didn't know my boss beaded the tire with ether so i was basically adding oxygen to a bomb. I can't explain how i survived. I never heard a bang or felt anything. I was instantly in an oil change pit, somehow completely unharmed. Watching this made all of the hairs on my body stand up and made it even harder to understand the outcome. It removed the roof on the shop and took the drop ceiling down in the office across the street, but somehow i was perfectly fine. I can't explain it. I'm grateful to be able to tell this story. I swear on my life it is a true story. Watching this just adds to my confusion.

I love how you perfectly captured the look of literally every tire shope ive ever seen

I'm an F-15 aircraft maintainer, and in our technical school training we are shown a gruesome picture of "Hamburger Man." He used a method of filling a tire called the "hot shot." Without a pressure regulator or gauge assembly, he used the high pressure (up to 4,000 PSI or 272 BAR I think) side of a nitrogen servicing cart to fill am aircraft tire. He miscalculated and the tire did a rapid unscheduled disassembly, which greatly increased the unfortunate bastard's surface area many times over.

“If anything goes to shite… it doesn’t matter” truer words have never been spoken.

As a tire technician, I have seen tires explode, especially with split rims, but when the technicians are airing up the tires, they are on their side, laying on the ground. It would be nice to see the explosion with the tire laying down and how high up it actually flies when it explodes, when you walk into a tire shop, take a look at the ceiling for telltale marks, now we have safety cages back then we used chains, but before that we did not have anything. Thank you for putting this on.

I had to watch this! About 55 years ago I was mounting a 15 inch garden tractor tire on a rim so I could use it on a home made dune buggy. I was kneeling down on a concrete driveway and holding the air chuck on the valve stem. Really don't know how much pressure went in, but the bead cable/wire broke in the bottom bead of the tire. The rim and wheel went straight up in the air through an aluminum car port and probably about 20 feet higher. I was stunned and when I came to my senses I was watching the tire and wheel come back down and bounce off the hood of my '62 Chevy p/u. Then I realized I was standing where I had been kneeling and I was holding my right arm with my left hand. Both bones in my forearm were shattered and had to have surgery with pins implanted. This is entertaining to watch, but not to live through. Everyone should be really careful with tires and air pressure. I'm very thankful I was not decapitated or killed!

The obvious next step is a quarry truck tyre. Those really aren't cheap though!

My comrade friends, I do this with basketball ago many years, yes. Done in a station for refueling of car. Strapped to the basketball was the hose for air. On lever was belt for air to go. Me and good friend stand back and watch ball explode. Very loud. Rubber pieces fly far. Basketball no good for the playing of basketball no more.

"Where the hell the rim went?" I just love the way you speak. You seem to have grasped the English slang very well. I can understand you easily. This was me at 12yrs, but on a smaller scale. Thanks so much!

You might want to look into getting your hands on some rupture discs for the next test. They can tell you definitively whether or not the shock waves themselves are lethal to a human where they're placed.

This was quite impressive. If you do this again, I may suggest having a pressure gauge in sight so we can see how much pressure the tire is at and know when it is getting close to critical pressure.

Always wanted to try this experiment since I started being a mechanic over forty years ago. Thank you. Loved it.

Changed my first truck tire at 12 years old, and I have done thousands of tires. Never had one come apart, giving GOD all the thanks for that. Old suicide wheels were probably the most dangerous from a mechanical standpoint. Split rings, 2 and 3 piece. Off-road heavy equipment split rings. I remember a Dart Clark loader at Cottonwood Arizona that had an ejector bucket, 50 ton bucket fulls. I don't remember the tire size, maybe 365/65R35. I know it took half an hour to let the air out the tire.

You should try a split rim wheel. They fail more catastrophically. Also, I think if you put a drying tube on the high pressure compressor input, you shouldn't get that cloud that obscures everything. The drop in temperature when the air expands causes the water vapor to condense.

I've experienced 2 tire explosions in my career as an automotive technician, a 16 inch split rim and a 24.5 inch HD tire. Definitely sobering experiences. I appreciated the safety equipment.

My family owned a construction company since the 1970's. In the early 80's an 18yr old kid was changing a split rim and didn't put the safety chains over it. It exploded and decapitated him. My grandfather, who owned the company and was a great man, never forgave himself for the accident even though it wasn't his fault. I'm a mechanic and refuse to do anything with a split rim because of all the horror stories I was told about them growing up.

I can tell you from personal experience, that as simple as blowing up a MTB tire is EXTREMELY loud. Blew up in my face and my ears were ringing for a solid minute after. Almost shattered the windows of the building as well

You had me at, "this professional arrangement." Never before have I seen such an excellent demonstration of why a beard net is important. I pity the calendars.

I remember about 50 years ago reading about a mechanic who was killed by an exploding tyre he had left on a compressor. The shape of his body was printed in the grime on the garage ceiling.

I used to be a tire installer one of the more senior techs and safety was always my top priority. Explaining split rims to the youngsters, proper bead seating techniques, not putting your fingers near the seat of the rim, never reaching over the top of inflating tires etc... it's not a dangerous profession if you are properly trained and don't try to do anything that you are not confident in the process/procedure of

PSI doesn't sound like much until you start counting all of those inches. A standard house door has about 3,000 sq/in. A nuke has an overpressure wave that does most of the damage and it crushes heavy concrete buildings at 7PSI over atmospheric. That's 21,000 lbs on your front door. Great content guys!!

7:45 truck tire casually walks out after causing total mayhem in the tire shop.

I worked in a tire shop for a few months years ago. We had a safety cage for inflating split rim tires in, made of very heavy gage tubing. It was notably buckled out from a previous tire explosion. I used it religiously.

I sell and repair high pressure breathing air compressors, including Bauer like the one you are using. I have been asked about air chuck attachments for the reels on the systems. While low pressure regulators are available this is a clear demonstration of why I will not install them on systems without those and proper relief safety valves. In an inclosed space this would be even more devastating. Great job!

When I was in my 20's I worked for a repair shop that also did big truck tire's and military vehicle tire's. I was asked if I was willing to help if needed, I said yes. So we had to take a safety class on changing the tires on a 6 and 8 wheeled military vehicle. During that class they showed a video of when the bead of the tire fully seated to the rim, with the tire laying flat on the ground and a Honda Civic sitting on top of it. The Honda jumped about 12 feet into the air!! We had a full steal cage we put the tires into while we aired them up. After 30 or so of those tires, it was trash!! There was an incident with something exploding, but fortunately I was doing my normal job at the time. It sounded like a bomb went off!! Shook the entire building, knocking off dirt and dust from the ceiling. Crazy stuff!!

Didn't expect the car tyre to be that energetic! Thanks for giving me anxiety every time I inflate a tyre now.

I can confirm this is how it happens irl. I had two semi rims pop off back in my last life, the tire stays and launches the rim across the shop. Both times it happened immediately after checking pressure at 85-90 psi, put chuck back on and turned away, boom. Both also were aluminum rims, the outside lip folded over on both.

That first explosion shows that it's not just the force of the blast but where the debris goes. You can see how the tire snags under his arm and around his head, taking them both with it as it continues on.

I work with an older farmer in the neighborhood. I stopped by one day to see a 60 year old man laughing like a kid. Once I figured out he had an old tractor tire connected to the air compressor on the driveway in front of the shop, with the regulator turned up as far as it would go. The first compressor maxed out at 120 psi, the second compressor maxed out close to 200 psi. It set outside the garage with 200 psi on it for over an hour. When it came apart it shook the barn and probably went 30’ in the air. The tractor tire was an 18.4 x 38 Tractor tire. It was old and dry rotted and all he wanted was the rim for a burn pit ring. Once of the sketchiest things I have ever been around. He wants to try another one in the center of a field with air and propane mix on a fire. Great Video, Thanks from Michigan.

Man that is scary shit. I had no idea the damage a tire exploding off a rim could do. Thanks for the enlightening info.

Great Vid. As a Mechanic and occasionally having to change tyres on HGV wheels, I was always very nervous when inflating them. Even in the cage.

This is a very serious issue for those that inflate tires for a living. Years ago I was at my local pub and two gents were looking very sullen. They just watched their pal get cut in half by a tire that exploded during inflation. No, they did not use the proper guarding.

Hell yes! I have been asking for 4500psi compresser content for a while too!

What a treat ! Greetings and love from Boston, Massachusetts.

This is probably my favorite channel on UKposts. I have yet to be disappointed. Anyway, I’ve seen a 19.5 tow truck tire take out an entire 20’x 20’ garage door. I’m just glad I was on the other side of the building when it happened. Y’all should try the biggest tractor tire you can find or even an old split rim, those things are nasty when the ring comes off. Stay safe and keep em coming, I await my notifications.

Instead of a 22.5, use an industrial tire that goes on a rim that bolts together. The 22.5 has a relatively light wheel, with a bead angle that allows it to slip over easily with a bit of deformation. We want the tire to blow, not the tire to slip over the wheel.

A guy in the next town from here was killed while filling a huge tractor tyre. The force threw him about 15 metres in the air and about 30 metres away. Every organ in his body ruptured with the force. What it did to him was not pretty, necessitating that he had a closed box funeral. That tyre shop now has a reinforced safety cage to accommodate huge tractor tyres as well as updated ones for truck tyres. Respect from South Africa 🇿🇦

Again, a good experiment with explosions. Thanks.

Very well done and a great demonstration of tire danger under high pressure.

07:43 everyone sing along ... 'you picked a fine time to leave me loose-wheel'

Former tire tech here, I loved the job but this is something I do not miss. Even for a smaller truck tire, it bows out the cages we used. If they were run flat with no signs of inner casing wear after repair, they typically go boom between 70-85psi.

This guy is great. He takes the stuff that the kids do on you tube, way up to an adult level. Serious business for sure. Great video and you have a new subscriber! Thank you. J Poll.

We had a really big and old towmotor forklift where i worked. i think it was from the late 60's, anyway on the front it had 2 wheels per side. Each rim was a split rim and you had to pay attention when changing them because you could see then bolts that held the ri together and the ones that held the wheels on. One day the wheels had to come off because the brake shoes needed relining. We would get younger guys that were in the local universities automotive course to help out around the shop doing cleaning, or oil other small tasks. The boss showed him what bolts to not touch and how to get the forklift set up to get the gear box out and how to lock the forks ram for safety since several lines had to be undone to get to the gear box. i look over 10 minutes later and he has the 1 inch impact, full throttle really struggling to get the wheels off so i go to offer some help and i get about 5 foot away and he has the correct bolts undone but i guess the wheel was stuck and he is loosing the bolts holding the rim together. i grabbed him before he even seen i was walking over and literally drug him as fast as i could around the back of the forklift since the counter weight on the back was like a 4 ton block of cast iron. (not sure of actual weight just saying it was massive.) and asked him what he was doing. he told me the rim was stuck, he had not let any air out of the tires and he figured the boss was joking with him about not taking those bolts out. needles to say we had a bit of a problem. we used video chat to call another cell phone and rigged it onto the end of s pipe and from a distance examined the wheel. kid was lucky the air pressure was so great it made the bolts next to impossible to get undone. of those 5 bolts he got one out completely and the other 4 loosened enough that it had a small gap between the 2 rim halves. we had no idea how to deal with it, or it get it safely deflated, or anything and made some calls. we ended up welding a steel spike onto the bottom of the bucket on an excavator the boss borrowed from his brother and just stabbed the tire of the one wheel. that was when it was decided to get the non split rims they sell for them before anything worse could happen. i know it may seem like we were chickens or way too cautious or what ever but we felt best to be on the safe side. we even called the large local tire shop that does all the heavy equipment and farm implements in the area and the first thing they said was get the hell away from it which we were and that even tho they had a mobile unit for going to farms their would be no way in hell any of their guys would go anywhere near it. they suggested shooting it. that was what led to thinking if we had a long spike to stab it but that would still mean somebody would have to hold it and then the bosses teenage son said we needed a real life transformer and that is how we ended up at an excavator. has anybody else been in any thing like that before or any better ideas?

I used to change and fill tires on split rims in the Airforce for c130s and a10s. We had to put them in a cage before inflating them for obvious reasons. You should try this experiment with a split rim wheel and only use a couple bolts so it will fail. It will be much more devastating than a traditional wheel and tire.

And this is why you do pressure tests with water and not air 💥

This was so cool. Great to see you guys are still making great video's and having fun

Glad to see Aaron kaufman is still working on cars

I can't imagine a better vacation than doing stuff like this. Thank you so much for the video!!!

I remember about 60 years ago seeing a picture of the aftermath of a tractor tyre doing this somewhere in Italy. The ceiling had the imprint of a farmer, who had forgotten what he was doing, and went back to disconnect the airline.

Amazing video, I’ve often wondered what this would look like and now thanks to you guys I know

The first tire was more hectic but the low speed on the bigger tire was so cool to see just flop like jello, man u guys gotta love your job, looks more like fun to me! Got me hooked, awesome job! ~ZJAK

lauri this was one of your best ideas ever

A friend of mine worked at a truck shop many years ago. One day a tire for an 18 wheeler exploded (locking ring wasn´t properly seated) it blew out several windows in the shop and also damaged the roof. Luckily they were at lunch break in another building when it happened.

You’ve come a long way since I watched you shopping for food years ago. You have made my day with this one! Bravo!😂❤

Great vid mate. That was fun. It is great to see both of you in the vid. Regards, Jas.

Excellent Video. I once exploded a bicycle tire while inflating it at a gas station. Damaged my eardrum! I can imagine what these explosions sounded like. Great job!

The scary thing about this video is that around the world there are set ups like this but with real mechanics who end up being a statistic. Great fun video but also educational and could save a life by raising awaeness of the danger of over pressured tyres.

Really cool! I always wanted to do this to air compressor tanks.

This was a great collaboration... Sean from Bikes and Beards was pretty brave for holding those tires like that.

The worker was so dedicated he even tried to stop the tire from rolling away after the explosion. Impressing!

Holy hell you have out done yourself again excellent work I can't wait for the next tire video 😀

Hey Beyond the Press. Love you guys, you rock! Imagine how much more devastating in an enclosed space/ room‼️‼️‼️💯

I just love when he says "concrete bunker"... lol *JA, SO WE ARE IN DA CONKREEET BOOOONKER*

Please... A moment of silence for the calendars....

There was an incident at a mine here years ago. One of those massive dump trucks was parked next to a hut, used as a break room. I can't remember the exact specifics but along the lines of the locking ring failed and it was flung at the hut with such force that it more or less demolished it. Fortunately no one was in it at the time. Site rules were updated to state that vehicles must be parked away from the huts and positioned such that if anything went wrong bits would go flying in other directions.

BACK IN THE 90'S.... I had a MEGACHAD customer bring me a huge slick that he had mounted by hand but couldn't seat the bead and inflate it. Fortunately, I safely mounted the rim so when the bead broke, I only got a black eye, bruised tailbone, and reminder of why I payed attention in the Safety Class. We became buddies and he turned into a great customer when later, I let him watch me mount a tire properly.

A guy was killed where we had our truck tires serviced in the 70's from filling an uncaged two piece rim. I was drawn to this video from that old memory...

I worked at Sears Auto 20 years ago and whenever we got a tire that had an egg in the sidewall we would put it aside to blow up later at night. It was dangerous as hell but we laughed so fucking hard every time and the sound of the weakened sidewall rupturing was so LOUD. I still remember the first time a coworker intentionally did it during the day and chunky tub (asset protection manager) waddled over from the main store to see what the loud boom was.

That pipe stand you made couple years ago has stood up well to many explosions. Prrriiti Guud. 👍

Simultaneous dual bead break! When servicing aircraft wheels, you must stand to the front or back (treads), not facing the side (axle nut), facing the side when a wheel fails is instant death or dismemberment.

Thanks guys I needed to see something ridiculously funny like this!! There is just too much heavy stuff going on right now. A good laugh.

I did not expect the rim to just go flying like that. But with the second tire the air blast actually blew out the wall before the rim could hit it.

Those truck tires are no joke, even at normal pressures. There's video of a mobster slashing a box truck's tire, and it blew him into the air and shredded his clothes.

Oh... my.... gosh.. you have another channel??!? Wow just found this... this is super awesome!!!❤❤❤

The blood-curdling scream right after the explosion really sets the scene

I'm gonna try this in my living room. Your warnings not gonna stop me!!!

Ok so I've watched all your explosion videos, but this is one of the most amazing and entertaining. Also, Hannah is funny ❤️

That was fun to watch------Thanks!

Now this is a most excellent thing to watch sir.

It's terrifying how much energy is released when those tires fail.

This actually serves an important purpose. People often take for granted how dangerous a tire can be if over-inflated. Even a small car tire will tear your face off if you were as close as the mannequin in this video was. Semi tires are like bombs if they explode.

This was amazing to watch. Wow.

Nice touch changing the calendar month with the second tire.

3:35 This is the ONE time EVER where the normal speed is BETTER than the high speed!!!

That’s crazy guys. Here in Australia the Truck tyers are pumped up in a steel reinforced cage for obvious safety reasons. The explosive force in a over pressurised tyre is incredible.

That was EPIC sir and mam, you guys rock

This is very good for people to see so they know the dangers of compressed air.

Been watching for years. Love the channel. Thank you for what you do. 👍🤙💯🤌💪👊

I had a good friend of mine lose his father to this when we were young. He got distracted by something in his shop and forgot he was filling a tire and it let go next to him. One of the few reasons i don't like air compressors in silent rooms where you cant hear them running.

If you try this again, you should get some burst discs and place them at several distances to see how far away someone would have to be to survive.

There was actually coffee in the Starbucks cups on the table. That kind of attention to detail is exactly why I love this channel.

Excellent video , thank you and you deserve more subscribers. I know that only 5psi air over a large area is a great force that people don't realize. 6 or 7 bar would be dangerous to life.
