I haven't had a single flat tire for 4 years on my motorcycle with tubeless tires. To think that everyday items that we normally use actually have some genius people behind them is pretty amazing
same
I haven’t had a puncture on my Tubed tyres on Honda for 5years of high mileage tours
@@zeez9053 my bike had tubed tyre punctured once in 11 years.
But the other tyre is fine 😁
@@kepler214 and u use the bike once a year
That's what youtube must be and is for : knowledge, and proper remuneration for such creators.
👏👏👏
Tire engineer here. Thanks for the great video. Just a clarification though, as the tubeless tires are made of different inner liner material (high air retention property), tube tire should not be directly replaced with tubeless tires, even if you have a proper rim contour.
Can't that be fixed by coating it with glue?
The inner of the tube tyre
People will go for the cheap option - doing it according to "code" is a luxury for people that can afford it.
Same for Bicycles. Rim needs explicitly "Tubeless ready"
How do they mean this, convert to tubeless tire? I thought that either the tire and rim require a tube, or the tire and rim are designed to be airtight and tubeless. Are they saying you can add a humped rim and toss the inner tube? Because that goes against what they said about permeable tires...
@@lu881 Applying glue can be a quick fix rather than a Engineering solution. Even doing so at a mechanic not advised as it would alter the tire performance in terms of wear, comfort and performance..
Physicist here, who worked on tire cord materials, and once attended a symposium on tire design, alongside a bunch of tire engineers. I was gobsmacked by the level of design technology in these advanced composites. I still have the book on tire design fundamentals, which runs over 300 pages.
Oh yeah tires have a shocking amount of engineering involved. I’ve seen a few videos on it and people have spent a lot of time trying to improve them over the last 100 years. You’d think it’s just a tire or something but has some of the biggest impact on performance when you get down to it. I live in the snowiest city in the US so they’re especially important here and add a lot of extra challenges.

Good. I don't want them to fail at 150mph.
I am just a regular guy and saw a video lighting up a tire for instant air tight. I know the science behind it but it bothers me whether the video just for a show or they really uses tubeless tire. Man I didn't know it is tubeless now a day. that is why curiousity arises why it should be tubeless and why air is not leaking. This video explain it all. So much complexity for a tire
It is ridiculous how this channel makes me feel like an expert on the subjects it explains although i have very limited knowledge on them
Haha, the dunning kruger effect
Sometimes that can be the most dangerous 😄
fellow intellectual
This video had lots of twists and turns; with their trick questions, at times it left me feeling deflated, though I didn't tire of it!
It was a "breath of fresh air!"
Even they aren't treading any new ground by reinventing the wheel, it still feels revolutionary.
A tyre seems such a simple thing, until seeing all the technology behind it! 🙂
Yah, there's also some pretty crazy engineering to make them quieter by spacing out the tread in a certain way. There's also the chemical engineering part of it too.
in a world built upon literally thousands of years of innovation and progress, truly simple technologies are a rarity.
@Wildlife Warrior USA is the only country that spells tyre with an "i" instead of a "y". Tire is being tired. No way is wrong, just different ways for different countries. Something most of us are taught in school. I learned English in Africa.
@Wildlife Warrior Yes, it's weird for me to see it spelled your way ;-) It's frustrating to see words spelled differently to the way I was taught to spell, yet they are correct for where they are used. Look up "Geordie in UK" for some weird English :-)
@Wildlife Warrior I didn't know Canada spelt it the same way as USA. I assumed they would use a "y" because they seem to use other British spellings, like colour, etc.
This mystery was in my mind from years, but now its resoved cuz of this animation...Thanks a lot❤❤
Same!
I feel old, I grew up with tube tires helping my father change in his spare tire, now you can only see tube tires in light trucks and trucks but newer trucks also slowly having tubeless as well
Out with the old and in with the new, if the new is better which it is this case.
I was learning more interesting topics from your CZcams channel
Thanks for your great work
I'll never get tired from watching your videos. Thanks for making this!
This is very interesting as im a Technician at a tire shop and I have to work with tires all day. Love to be informed more about the things i work with everyday! Thank you!
Beautifully explained. Can’t get easier than this . Thanks a ton .
Very nice explanation. Thank you for making this such a nice video!
Thanks for the video, it's given me a much clearer insight to tubeless methods on a push bike.
Loved the explanation of this video. I learnt everything explained. Thanks. My old tubeless tyre developed a crack two days back and I replaced it today and am amazed at how the principle of tubeless Tyre works.. 👏👏👏👏
I really like this channel, it clears my maximum doubts
Clear explanation and a perfect animation.
Thanks to those master minds behind this Tyre technology which helps us in a smooth ride on road.
This channel deserves a billion subs...u can visually understand everything i love it!!
Thanks for this tutorial.
A simple difference, we didn't know.
wow i haven't seen tubed tires for cars my whole life. bicycle tires, on the other hand, is much more commonly seen with tubed tires although tubeless has been out for a while and extremely popular.
Not sure about other parts of the world, but in the US tubeless tires started replacing tubed tires in the early 50’s.
Note, tubes cannot even be installed in tubeless tires because, IIRC, wall strength and thus friction, leading to wear and ka-boom.
Some Soviet cars had tubed tires.
I've worked on cars for about 10 years now, NEVER seen a tubed tire. Fast, slow, cheap, expensive, old, new,... Always tubeless
Belgium btw (so European cars mostly)
For bicycles, tubed tire works the best.
Amazing videos with simple explanation, hope these get played in school during science periods for students. Keep up the good work.
😂😂😂 100₹ lol
The Best CZcams Channel I'd ever visited.... subscribed instantly.....♥️
Thanks for making us understand these stuffs ....🙏
Thanks for an extraordinary and useful video at this hour of need. It will certainly inspire the interested car users.
I'm going to be labelled pedantic...
My understanding:
The radial forces are applied by the pressurised air (i.e. the forces act along the radius). The balloon surface is under tension (circumferential force, not radial). When the puncture occurs, the local tension is released, meaning the surrounding tension pulls the surface away, creating the rupture through which the air rushes. The balloon tears itself apart.
Similar to cutting a stretched rubber band.
no one cares and also yes you are pedantic..
The tires with the tube disappeared more than 25 years ago.
A car with balloon tires was a liability at speeds over 70 km/h, because the sudden change of direction above that speed was not controllable anymore. I recall after a long drive on the motorway - with my first car in 1981 - I felt grateful to Haven that it went smoothly. I had a couple of tire deflation at low speed, it is unbelievable how quick the tire went from being fully inflated to being totally flat in less than 20 seconds. And this was caused by a stray screw or small piece of metal - casually present on the road - that punctured the tire. Even a pothole once blew the balloon tire.
I'm grateful to the industry that came up with tubeless tires. In the beginning many drivers complained about the costs and the non-repairable nature of the new tires, but whoever had a balloon tire incident knew better and quickly swapped for the new tires.
Thanks for the video...
Tube for car disappear long ago, but you can find lot of vehicle using tubes nowaday : bicycles, lawnmower, tractor and trucks
@@Dread262 and some classical cars aswell
Really informative and wonderful video from Sabine and team. Great work guys. Really love you.
Excellent explanation.Thank you for making such, easy to understand and simple videos.
This is not good nor correct explanation.
Majority of tyres don't have "hump" on rim. Air pressure keeps tyre pressed against rim and they form airtight seal. Hump may only help when tyre is deflated to keep the bead from mowing inwards and tyre collapsing.
Also balloon analogy apply to all car tyres since they all have reinforcements inside, and won't explode. Difference in tyre types is that tubed tyres are not airtight around bead and will deflate faster when tube is punctured, while in tubeless the air can only escape through puncture hole.
This video gives us the most easiest and simplest way to understand about the difference & working of both, a tubed tyre as well as the tubeless tyre.
Thank you Lesics team for the wonderful animation and explanation which helped us to grasp this concept.
Tubeless tires saved my life. Once run at 80km/h for 10mins before noticing i was running flat. Yep, driving that fast and long for 20mins.
It did made a sound for that time being and ignored it because i thought it was just loose cargo from the back. Had to stop because that sound was not normal.
Thanks a lot for the knowledge
This video makes me to learn a lot
by the most simplest way
Thank you for clearing the concept!
Also thank you for the enlightenment. Tubeless tyre is the real deal. Easier to maintain (patch). Picking a nail with tube tyres deflat easily but with tubeless it can even get you to your destination.
Very insightful and great visual explanation 🤓
Always great and knowledgeable content. ThankYou Shabin sir❤
Very good quality of your job!

If I had found your channel during my high school, i would have loved to go for engeneering. You're so good
wow. this is some incredible explanation and illustration.
I love your videos
Excellent video , you made us understand the mechanism well better than our classroom 💫
I've been a tire technician for decades. Very fascinating...
I was curious about how the tubless tyres locks air tight.
And i still wonder how is that hump is capable of locking air so perfect in millions of tyres.
Wonderful
Awesome. Very well illustration
This video is lot better & understandable than school teachers
Very well explained. I enjoyed it and also learnt few new things about the fitting of tubeless tyres.👍👍👍
Honestly, I never thought it so well. I got my puncture repaired while I was awe struck for like 10 minutes, and then I got busy into my life. Until now, I didn't know how amazing this is!!!
Keep these interesting and informative videos coming.

I learnd more engineering from CZcams animation videos than my four year course
I have been using a car with tubeless tyres for eleven years. I thought that perfect sealing between the rim and the tyre was achieved by precision machining of the alloy rim. That rubber under pressure would fill the tiny gaps if any. I am glad that at last I got the opportunity to learn about this engineering achievement. Many thanks for the instructive video.
Simply amazing 🤩👌🏼
Thank you for your efforts
Thank you from Europe for the educational videos.
I believe the expansion of the balloon (4:10) is what creates the tension forces at the surface. When you puncture it with the needle, it basically disrupt the equilibrium of forces on the material and now all the stress need to be supported on the surrounded material, which is now weak due to the needle stripping it. Thst explodes the balloon. You can demostraste it by expande the balloon without filling it with sir. After puncturing it, it strips away. With no air flow around the needle.
But he's talking about tyres so the air filled demonstration is appropriate.
@@gn6691 - but still wrong.
@@FerdiLouw what's wrong?
@@gn6691 It is not the airflow around the needle that causes the balloon to burst.
Exactly what I was thinking. Airflow does not make the ballon pop out, its just the tension applied on all surface points of the ballon material due to expansion from the air inside it. The popping is because the surface points of the ballons are now un unequal tension state.
Today I bought 2 tubeless tyres for my bike. at evening I got recommendation for this video.
Great visualization and easy to understand the concept
Love the animations here. Great video and well explained.
We would love to see if you can make a working of different kinds of compound bow tiggers....
I like how you start with a simple experiment and make us think. Then slowly everything unfolds -- idea, trials, more problems, better solution, and finally, a near perfect solution. A unique way of making students appreciate good engineering.
Excellent description of the concept... nice graphical inserts
All my doubts cleared thank you so much ❤️
Wonderful, really searching for that explanation!
If you hope i enjoyed the video, yes of course i did, thanks for sharing
These animations are on another level 👌
Thank you very much for explaining modern high-tech engineering techniques and principles in easy-to-understand pictures.
2:24 so what you are telling me here is that the outer body of the tire, which keeps the tube in shape is strong enough to do that, but not strong enough when the damn air leaves out of th tube due to a puncture.
If braking a wheel at maximum force, the tire can in some cases rotate/glide on the rim. This will immediatly destroy the valve if fixed on both the tube and the rim and cause a sudden loss of air pressure. This happens usually in the worst situation (full braking needed). Tubeless tires can rotate/glide without destroying the valve or the tube.
My bicycle has tubed tires. I had lots of flat tires with nails an glasspieces in it. But I had never an exploding tire.
Thanks man!
I was so confused about this....u just made it so easy thanks
Excellent video, I clearly understood the technology behind it, Many many thanks
I can't remember the time I've seen a car tire with a tube in it

"This is a nail. Nails are sharp because someone sharpend them and that makes them pointy. If you press a pointy nail into something soft, so long as the nail is harder than the material it's pressed into and the force exerted is great enough to drive the surface of the point forward, the nail will move in the direction of the force applied. This will likely cause a puncture in the softer material, as the nail will have to puncture it to be able to move forward. This is why nails can be dangerous when driven over. Driving is usually done on roads, which are not made of nail, but can contain occasional sharp objects due to other drivers carelessness. Nails are friction based fasteners often used for bonding wood in construction and other applications. They are usually steel, but can be made of other materials like aluminum. These materials are almost always harder than the rubber compounds used to produce automotive tires, and most nails are intentionally sharpened to make it easier for them to penitrate a variety of different material, usually far more durable than a rubber tire. When a force is applied to a nail, usually the upward force applied by an asphalt roadway, equal and opposite of that exerted upon it by the weight of a passing vehicle, the nail can be forced to permiate an automotive tire and cause a puncture."
Dude, who is this video for? Imagine you're considering swapping your fully restored classic car over to tubeless tires for safety but you don't understand the concept that a balloon will pop if you stick a pin in it.
You owe me at least 4 minutes of my life back. Plus the time it took me to write this comment.
If he actually said what you wrote, you would have a point. But he didn't, so you don't.
@@jdb47games you are right. What's simple to me might not be so simple to someone else. I know cars, but I have been learning how to count in Spanish feeling stupid.

A fatal crash. Well that escalated quickly.
Thank you for very simple easy to understand explanation
i want to understand it from many times but this is understand me properly. keep it up.
This video define the engineering. And genius people's behind every smart object.
I wonder how CZcams got to know that I've had doubts about how tubeless tire is made possible!
Keep making these forever please.
it was just poped up in my mind while riding to home, now i can have a good night sleep, thank you.
Gamer here, I don’t understand physics so I recommend going to Los Santos Customs as they can fix your tires from gunshots.
and also make it bulletproof for 25.000$
Very informative content! 👍❤️
One inconsistency though. First it's said the tubed tire is permeable hence can't hold air by itself. In the end, it's said that you can convert from tubed to tubeless just by changing the rim. What about the permeability of the tire material discussed earlier?
It'll leak over time. so it "works" just not ideal vs an actual tubeless tire with reduced permeability.
what he meant was you could replace( not convert) tubed tire with tubeless.
Amazing job 😊 simple and precise explanation ❤
Amazing animation and clear explanation. Thanks for this video
Unfortunately this is not good nor correct explanation.
Majority of tyres don't have "hump" on rim. Air pressure keeps tyre pressed against rim and they form airtight seal. Hump may only help when tyre is deflated to keep the bead from mowing inwards and tyre collapsing.
Also balloon analogy apply to all car tyres since they all have reinforcements inside, and won't explode. Difference in tyre types is that tubed tyres are not airtight around bead and will deflate faster when tube is punctured, while in tubeless the air can only escape through puncture hole.
You should have mentioned how driving on a flat tire (tubeless obviously), for any distance, completely ruins the lining inside the tire, technically making the tire unsafe. If you've ever repaired a flat, you know instantly they have driven on the tire because the moment you break the bead and see inside the tire, its filled with a black powder.
2:20 Why does the tire explode? If it was able to hold the air pressure before the puncture, I’m not seeing how a puncture would suddenly make it able to explode.
As shown in balloon case, the air will try to escape from the puncture region, and since the pressure is high, it will likely rupture the tube and tyres.
The tyre (and tube) has tension when there is air pressure.
When there is hole in the tyre, the tension (tyre stretching because of the air pressure) causes the hole gets bigger.
While the hole gets bigger, the punctured site becomes weaker to tension. This makes the tyre more vulnerable to tension, making the hole even bigger. Eventually, tension will rip apart the punctured site, causing an explosion.
Edit:the same thing happens to the tube, but the tube won't pop. Only the hole gets bigger
In fast tyre deflation, the air can escape through the valve also. Hence the air pressure decreases rapidly, so as to reduce the tension on the tyres.
I.e. not cause the tyre to rip apart.
@@Abedchess But the pressure -> stretching effect occurs with the tubeless tire too, so I’m not seeing how it’s unique to one design or the other.
The balloon pops because the rubber is stretchy and the escaping air has that servo effect. A tire is not very stretchy, regardless of whether it is tubeless or not.
@@MaplePanda04
In tubeless, the tyre and tube are glued together.
This provides support against tension, making it harder for the hole in the 'glued tube' to get bigger.
Like a balloon with tape. The tape is helping to resist the tension, making it harder for the hole to get bigger.
@@MaplePanda04 In a balloon, the tension pulls in all directions around the balloon.
In tubed tyres, the air pressure transfers from the tube to the tyres. The tyres cannot withstand the air pressure , and rips the tyre at the weakest point.
I.e. the puncture point
In tubeless tyres, the tube and tyre are glued together. Both provide support against the air pressure. Making it harder for the hole in the glued tube to increase.
The tyre will not burst because the 'glued tube' is transferring air pressure directly outside
This is really a great explanation about tubeless tires 😮
That nail used to puncture the tube was giving a wild smirk
Sorry but tires with tubes do not pop like a balloon when punctured. I drove cars with tube type tires 60 some years ago and when a puncture occurred I removed the tube patched it put it back in the tire and drove on. Sometimes I would air up the tire and repair it a day or two later. Good information other wise thanks for the video
Salute to the engineers...they are literally one of the most underrated professionals ( in INDIA atleast )
This is literally my favorite channel 😍
I love your's all video realy they are teachable tnx a lot God bless you
kind of interesting that this is being presented as a cutting edge tire tech but literally every car tire ive ever seen in my life was tubeless
Well That depends on how old are you?
@@ankityeshpattnaik936 i mean i think regardless of my age unless im like 3 years old it kinda suggests that its not exactly cutting edge stuff
@@estergrant6713 no he means, how old are you as in what time era were you raised or something. Tubless have become pretty much a standard over the last 20 years because so many people and statistics agree that the tubless models are safer and more efficient
@@A_very_tinly_can thats my point is that my age is irrelevant because my point is that its presented as new technology but as you said it has been standard for the last 20 years.
@@estergrant6713 oooh now i get what you mean
For aircraft landing gears the rims are divided into two -outer and inner rims .joined by tight bolts.
its called a bead lock. most off road trucks or rally cars have it. especially rock crawllers or extreme heavy equipment
@@jamesporter. They are not beadlocks, rather they are two halves.
Thanks for sharing the interesting innovation 💡
Excellent animation and explanation..... 👏🏻
Also to mention that a tubeless tyre is light on the shockers compared to the tyres with tubes.
Also I felt that tubeless tyres are lighter than tyre and tube assembly.
More importantly, they run cooler due to the lack of friction between the tire and the tube, which leads to less wear per mile and longer lifespans for the tire.
It also allows them to run at much higher speeds for longer periods without failure.
I had no idea that some tires had green ghosts inside them that help to seal punctures.
such a great explanation!
Well explained.got my doubts cleared.thanks a lot
Hey @Lesics
Can you please make a video about the engineering behind ATMs. I would really appreciate to learn about it.
