Tubeless Tire | The interesting Physics behind it 

That's what youtube must be and is for : knowledge, and proper remuneration for such creators.

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

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.

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

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.

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

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!

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.

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

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!

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

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...

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

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.

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.

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.

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.. 👏👏👏👏

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

This "simple" yet genius solution is right up there with the bend in the toilet bowl or sink. So simple yet so practical. Nice video.

I was learning more interesting topics from your RU-vid channel Thanks for your great work

Gamer here, I don’t understand physics so I recommend going to Los Santos Customs as they can fix your tires from gunshots.

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!!!

Thank you for your kind information about the difference between the tube type or tubeless tyres exactly.you are a Genius because you have shown the right engineering technique what real happens while driving on the road.

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.

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.

"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.

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

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

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

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

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

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.

Thanks for the video, it's given me a much clearer insight to tubeless methods on a push bike.

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

Key points discussed with excellent demonstration

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.

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

I learnd more engineering from RU-vid animation videos than my four year course

I really like this channel, it clears my maximum doubts

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.

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

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

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

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

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

0:05 rip 🫡

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!

Very insightful and great visual explanation 🤓

I love how you made the animation for fitting a tubeless tire onto a rim look so easy when in reality I had to wrestle with a trailer tire for a solid 10 minutes in the grass getting it on with just a couple screwdrivers

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

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

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.

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

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?

These animations are on another level 👌

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

The guy explaining the tape and balloon is surely from kerala 🌴, India 🇮🇳..implies a malayali (മലയാളി) Anyone else thinks so?

I wonder how RU-vid got to know that I've had doubts about how tubeless tire is made possible!

My best Science teacher Mr.Sabin❤️

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

Thank you for clearing the concept!

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.

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

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.

Doesn't the steel belt (didn't get mentioned) built into the tire serves the same purpose as the tape to the balloon?

Great visualization and easy to understand the concept

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

Great video. I've got to know modern engineering increase much safety to the tires.

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

Thank you from Europe for the educational videos.

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.

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

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

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

Keep these interesting and informative videos coming.

Great video, love the animations

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

I have the dreaded Run-on-Flat tires on my BMW as they (say) they wanted to save on having to carry an on board spare wheel (weight, space and cost for the OEM). I say Dreaded as they give a much harsher ride due to their thicker sidewall construction AND they cost significantly more than a non Run-on-Flat. Id like to see a video on the engineering behind this tire that claims to support the full weight of the vehicle when flat and allows you to continue driving a significant distance, at a lower recommended speed of course.

At 1:04 you mentioned that the material of the tire is Air Permeable, and air can escape from the surface of the tire. So, in a tubeless tire, along with the rim, the material of the tire also should be changed. Right ??

Great explanation ive learn a lot about tube and tubeless

I had no idea that some tires had green ghosts inside them that help to seal punctures.

Wow, thanks a lot

This video got posted right when I was looking to learn about tires. Great.

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

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

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

Woww amazing tutorial 😍 👌

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

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

Amazing how all the hundreds of flats my family has had over the years running tube type tires and not one time did anyone lose control and crash. Tubeless tires are a good thing, but the old ones weren't dangerous.

for so long I wondered why the tires pop suddenly when they filled it with air (when putting a new tire on the rim) thanks for the valuable information 7:00

Wonderful, really searching for that explanation!

Thank you for very simple easy to understand explanation

A fatal crash. Well that escalated quickly.

Simply amazing 🤩👌🏼 Thank you for your efforts

Why would a non-tubeless tyre burst if the valve was not allowed to be pulled in and allow air to escape quickly? That seems strange, it's the tyre that resists the air pressure, not the tube. Would the air permeating the tyre material cause damage? It wasn't explained correctly I'm afraid

So nice and beautiful explanation

I'm confused by how you specify that a hole that is allowed to open widely causes a fast release of air and rapid deflation is seen as preferable, but then offer the "sticky tape" method as a solution to the blowout problem. It looks like you pointed at a problem, and then recreated the problem in a similar context and called it a solution.

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