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

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.

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.

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

A tyre seems such a simple thing, until seeing all the technology behind it! 🙂

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!

This mystery was in my mind from years, but now its resoved cuz of this animation...Thanks a lot❤❤

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

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.

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...

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.

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.

Amazing videos with simple explanation, hope these get played in school during science periods for students. Keep up the good work.

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.. 👏👏👏👏

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!

I was learning more interesting topics from your UKposts channel Thanks for your great work

I'll never get tired from watching your videos. Thanks for making this!

Thanks for this tutorial. A simple difference, we didn't know.

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.

Beautifully explained. Can’t get easier than this . Thanks a ton .

This channel deserves a billion subs...u can visually understand everything i love it!!

Thanks for an extraordinary and useful video at this hour of need. It will certainly inspire the interested car users.

Very nice explanation. Thank you for making this such a nice video!

I really like this channel, it clears my maximum doubts

Thanks a lot for the knowledge This video makes me to learn a lot by the most simplest way

Key points discussed with excellent demonstration

Clear explanation and a perfect animation. Thanks to those master minds behind this Tyre technology which helps us in a smooth ride on road.

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!!!

Excellent explanation.Thank you for making such, easy to understand and simple videos.

ITs amazing method to explained how the things work and 3d animation awesome. Simple to understand by visual and how technology grow day by day. Thank you very much!

I've been a tire technician for decades. Very fascinating...

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.

Great visualization and easy to understand the concept

complicated topic understood in a simple way. keep uploading more videos.

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

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.

Excellent description of the concept... nice graphical inserts

These animations are on another level 👌

"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.

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.

Thank you for clearing the concept!

Thank you for very simple easy to understand explanation

Very insightful and great visual explanation 🤓

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.

Excellent video, I clearly understood the technology behind it, Many many thanks

Thx brother , excellent animation and explaination 👏🏻👏🏻👏🏻

If I had found your channel during my high school, i would have loved to go for engeneering. You're so good

Really informative and wonderful video from Sabine and team. Great work guys. Really love you.

Excellent video , you made us understand the mechanism well better than our classroom 💫

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.

Keep these interesting and informative videos coming.

Very good quality of your job! Than"s a lot! Me and my family always glad to see new videos on your chanel.

Love the animations here. Great video and well explained.

Today I bought 2 tubeless tyres for my bike. at evening I got recommendation for this video.

For aircraft landing gears the rims are divided into two -outer and inner rims .joined by tight bolts.

The Best UKposts Channel I'd ever visited.... subscribed instantly.....♥️ Thanks for making us understand these stuffs ....🙏

wow. this is some incredible explanation and illustration. I love your videos

Thank you lesics team. I have been watching your video since when you were "Learn Engineering". Your content is unique and helpful for everyone. Thank you again Sabin sir

This video define the engineering. And genius people's behind every smart object.

Thank you for this discussion

Awesome. Very well illustration This video is lot better & understandable than school teachers

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.

We would love to see if you can make a working of different kinds of compound bow tiggers....

Thank you from Europe for the educational videos.

Thanks for sharing the interesting innovation 💡

Salute to the engineers...they are literally one of the most underrated professionals ( in INDIA atleast )

Still some old budget cars use Tubed Tire, never seen car becoming uncontrollable when Tubed tire gets punctured. In my experience we had Alto with tubed tires and we came to know that all the tires got punctured at same times but did not feel car becoming uncontrollable, probably because it was at low speed.

Thanks for this very useful video !!!

I was so confused about this....u just made it so easy thanks

I learnd more engineering from UKposts animation videos than my four year course

If you hope i enjoyed the video, yes of course i did, thanks for sharing

I love your's all video realy they are teachable tnx a lot God bless you

Best Video, well explained 🙏👍

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.

Another advantage of tubeless is since the inner rim of the tube is removed, it makes the vehicle lighter, thus saving the fuel costs. This is the reason why they're start using it in 1947 Would be nice to have a video about the famous airless tires & see the advantages in details

Thank you very much for explaining modern high-tech engineering techniques and principles in easy-to-understand pictures.

7:08 that's super dangerous. I'm lucky to be alive after doing it and having the tire blow up.

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.

Wonderful, really searching for that explanation!

That nail used to puncture the tube was giving a wild smirk

Always great and knowledgeable content. ThankYou Shabin sir❤

A tube type tire can hold much greater pressure than the tube anyway, but the pressure doesn't increase inside the tire just because their air is outside of the tube. The tire is still holding the same pressure throughout the entire volume of the vessel

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?

thanks a lot for this easy understanding video.👏👏👏👏

Wonderful!! Thanks.

A fatal crash. Well that escalated quickly.

I can't remember the time I've seen a car tire with a tube in it

Thanks for the explanation, kind regards.

All my doubts cleared thank you so much ❤️

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.

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

Keep making these forever please.

i want to understand it from many times but this is understand me properly. keep it up.

Hey @Lesics Can you please make a video about the engineering behind ATMs. I would really appreciate to learn about it.

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

it was just poped up in my mind while riding to home, now i can have a good night sleep, thank you.

Well explained.got my doubts cleared.thanks a lot

My car rim does not have the hump. Internal pressure keeps the edge fixed with the rim. It was worth the investment.
