Yeah, because a business as big as Michelin couldn't possibly work that into their pricing models. And the tread won't last any longer than any other tire. The only thing that will be extended is tires that get a sidewall puncture or uneven wear. That's a small portion of tires sold.
They shouldn't last any longer on average then regular tires. Most tires are still going to need replacement due to tread wear, this tire seems more resistant to factors that will prematurely shorten their lifespan.
"Gaining traction" is more than just a good pun, it's a much cleaner phrase than "starting to get imminent." What does that even mean? It's like saying they're "about to be about to be on the market." Both redundant and confusing.

@@bigk777 Well no matter what the tread is no different than any other tire, it will still wear out the same. The ribs in the middle should have no problem lasting as long as other tires, it's really not any different than what the sidewalls already do. They basically just moved the sidewalls.

This is amazing technology. The Michelin Tweel is already out for Skid Steers/light construction and the performance is amazing. I’ve seen this technology handle gravel, rocks, mud, and metal rebars. If they can mirror that technology to cars then this will be a huge innovation.
How is the noise when compared to a regular tire? Granted they’re obviously not being handled at high speed at all but have you noticed any difference?
The noise is not bad. When it comes to skid steers the machine is louder that tire noise when operating the equipment. It is quieter when compared to tracks or solid tires but of course it depends on the application you are on. A tire is like a tool and needs to be used for the correct job. As far as a gimmick, I have personally tested the product the tire performs very well when running over cut metal, rebars, broken concrete. Again it depends on the job. 👍🏽

We also want to know how much traction they'll get in launch mode, and how many varieties will be required for the full range of loads and vehicle classes. One great thing about air-filled tires, is that you can calculate or adjust 'hardness' by air volume/pressure, and density of material.
Non-pneumatic tires have been around for a while now. Lots of ride-on lawn mowers and other farm/industrial equipment has been experimenting with them. They have flaws though. They are very hard to keep balanced because things can get stuck on the inside of the grooves and at high speeds, they are aerodynamic nightmares.

Not so obvious, and not so easy ;-) adding those outside walls would prevent those tires from having the way they are now (bending on obstacles) - which most likely would make them fail and break fast

Also why is this tech taking so long to develop, its been years and years they mention this tech. Tin hat conspiracy is that they last too long and Michelin isnt down on cutting its profits for the sake of consumer convenience and perhaps the research is on how to make them not last as long while not breaking apart too early.
I drew up a design for something exactly like this back in 6th grade, wheels with no air, strong but able to be bent out of shape without losing its original form as to move over potholes or debris in the road...guess i should've put in a patent for it
While you're at it, why don't you imagine a rocket fast enough to reach the next galaxy in one minute? Thinking of stuff is not akin to making them. Airless tires have been a thing for a long time but never been practical exactly because of the limitations which you used your imagination to move past
What happens when you live up north, and get in your car when its been parked in frozen ice/snow over night, and the gaps in the tire are completely full of ice?
This was the very first thing I thought of as well. It’ll be great for 3 seasons. Winter comes around and you’ll be riding around on traditional winter tires. 🤷🏻♂️
You know, I watch CNET on topics I like/know just to see them butcher it due to a lack of knowledge/research. This time I actually liked this guy, he was succint, clear, and raised good thinking points. Learn from this guy!
You forgot to ask two key questions. will it hold up at top speeds of the EVs it may be used on, and can it ride as comfortably as a pneumatic which takes that bump and spreads the impact to all 360 degrees of the tire casing? Airless tires for bicycles have been around for some time now and they ride rough. Michelin has been developing this technology for the military, where rough riding is a given, and top speeds are severely reduced in most cases.
This biggest hurdle with the Michelin airless technology is DOT approval. It required numerous testing and needs to meet standard for vehicles such as weight, speed rating, and must pass safety tests.
Hello. Many people here are confusing this with the Tweel, which is another Michelin similar design but for industrial usage, mainly forklifts and it came out so long ago. its a really high profile tyre and those wheels look custom, i doubt they can be fitted on drop center rims since there is no pressure to hold the beads in place. Moreover, snow and mud with not affect it and they are easily evacuated and ABS and other systems should work just fine because it cant be a functional tyre if it is not transmitting all the forces (grip,brake,steer,carry loads...). Noise is a tricky question.. theoretically should not be higher, all of it is generated in a small contact patch area maybe the spokes can absorb much of the vibrations generated or maybe the absence of an air chamber will produce something totally different,.. hard to tell. Sorry for the long talk.. for the tyre nerds. Peace.
I think this is one of the most brilliant inventions ever, I hope getting it from testing to market goes smoothly and these tyres are available by 2024 as he said👍
I'd like to see what happens when a puddle freezes around the tire and in these spokes. There will need to be a cover to keep ice and debris out. How long do the spokes remain flexible and what happens when the treads wear out?
@@longfang98 : Yes but do they last longer... or significantly longer? Are these more recyclable or will there just be piles of these instead of pneumatic?
If i can fit them on my wheel i will try em as soon as they come out. Had 2 flat tyre's in 1 week last year both could not be repaired. Had no money to replace them so changed to winter wheels in summer...
I'm really curious about sound. in my mind, that design begs for wind (at certain speeds) to cause a whistle or a hum as it travels through the tires(like blowing into a bottle. plus, I feel like a sidewall is needed because in areas where you get snow/ice, last thing you need is ice or super packed snow in between the "spoke" causing issues with traction/control. Lastly, how many punctures can the tire sustain before I have to replace the tire. the more holes in the tire, the less structurally sound the tire will be. if they say something like 3, then that's probably not worth it especially when a lot of places patch tires for $15 (or even free here in Indy).
bruh how has this guy not popped up in my feed sooner he actually locks your focus in lol ( i have adhd ) its hard for me to stay focused lmao but this guy does it so well im unsure why
Several years ago we at Polaris built about 200 Military 4 wheelers with airless tires. I know this because I drove many of them . (just into the truck to load them but still)
I remember them coming out with this like 10 years ago. I am sure tire companies do not want these out on the roads because it would be terrible for business. And money and greed will always win out.
im sure they will have rubber side walls once these are mass produced. It looks like this now because they need to demonstrate how it works. at least I think so

Do your homework cnet! These are a complete Michelin failure 10+ years ago when they first tried to release them and are simply trying to milk the dead cow again. Several auto manufactures were interested until they learned modifications to the chassis where needed, extra tyre weight, couldn't use existing rims, and the cost which is 4x that of a normal tire. Ohh and the real kicker was Michelin wanted to sell them "special" equipment to work on them! Really the only benefit you get is no flat tires and you loose sidewall stability, ability to vary tire pressure for change in conditions, low cost, and low weight of a traditional tyre. BTW they couldn't leave those ribs open as mud, snow, ice, and rocks would create balance issues if they got stuck in there. If this was a good idea you would already see them on race tracks and you don't as they aren't any good.
I've been watching Brian on CNET since my middle school days and he's just as sharp as then! I think he was the one who introduced me to Ubuntu (probably 8.04) via some ancient video
But there is problem when we apply the breaks ,when we apply breaks at a particular time it will take some time to be stopped at the place where we apply the breaks..The material bends it self and moves from the place where we apply the breaks.
I would love for these to work, because pneumatic tires definitely have major weaknesses. But, I still have questions: Are they heavier than pneumatic tires? Are they as efficient as pneumatic tires? Are they as comfortable as pneumatic tires?
When it fills with mud or sand or rocks?? Just one rock or anything on road will cause a severe imbalance which at speed would disintegrate the tire. Maybe they come up with a one unit solid wheel tire combo
You feel every little bump. It’s 3 times more felt than a tire with air. I’ve driven equipment that uses these type of tires. We kept popping the air filled tires, so switched out for these. They are not fun to use.
they have been available for a couple years for ATV side by side s, up to 2x the cost, spacers may be needed to fit proper, my friend having a tire store says he is scared of them, like CROCKS they don't wear out
If you you stretch and contract a rubber band often enough it will break by "fatigue failure". The sidewall sections in this tire flex much more than ordinary pneumatic ones on every rotation, so I doubt that they will last as long.
I have no idea how you'd mount these, i work in a tire center, and it's baffling. My guess would be that it'll be a tire wheel combo that you have to replace both every time
I'm hoping the sidewall is covered in the production model. I know it looks cool like that, but it only takes a little bit of mud or snow to get stuck in those fins to make the tire unbalanced.
My biggest concern is how they work in wet or snowy conditions. How does water or packed snow/ice affect that plastic compound their using instead of having a sidewall?
what about test with snow chains on it. I think, in mud or snow it has many disadvantages. What is more, in air tire, you can increase pressure when heavier load is expected, or lower the pressure when needed etc. Here you cannot adjust these tire properties.

While you're at it, why don't you imagine a rocket fast enough to reach the next galaxy in one minute? Thinking of stuff is not akin to making them. Airless tires have been a thing for a long time but never been practical exactly because of the limitations which you used your imagination to move past
What happens when you live up north, and get in your car when its been parked in frozen ice/snow over night, and the gaps in the tire are completely full of ice?
I think the sides don't need to be open. They've just done it that way because it looks different.
This was the very first thing I thought of as well. It’ll be great for 3 seasons. Winter comes around and you’ll be riding around on traditional winter tires. 🤷🏻♂️
Let's hope they're covered up when commercially available.
@@ideaynojodas I suspect they will be, because the open tire looks kind of ridiculous.
I saw this like 15 years ago...been a long time coming man
How will the tires do on a Moose avoidance maneuver? With that design I would feel the tires with lean way too much
I remember seeing these years ago! Cool to see them again
I remember seeing articles in popular science back in the mid 80's about these tires. Color me skeptical.
I think they been ready since then .
I was just gonna write this. I had to look for it first. Lol
Most of the technology you use has failed prototypes from decades earlier.
@@qsam-yq9vv Even in the 80s they were saying it was just around the corner.
You know, I watch CNET on topics I like/know just to see them butcher it due to a lack of knowledge/research. This time I actually liked this guy, he was succint, clear, and raised good thinking points. Learn from this guy!
Ok? That's nice, but for how long it will be functional before it loss its flexibility?
15 minutes on the great Indian roads.. oh yeah!!!
@@manoharmeka999 🤣
How long will they last when exposed to the elements, especially extreme heat and cold?
@@manoharmeka999 🤣👍
I remember reading about the twheel in popular science almost 2 decades ago.
You forgot to ask two key questions. will it hold up at top speeds of the EVs it may be used on, and can it ride as comfortably as a pneumatic which takes that bump and spreads the impact to all 360 degrees of the tire casing? Airless tires for bicycles have been around for some time now and they ride rough. Michelin has been developing this technology for the military, where rough riding is a given, and top speeds are severely reduced in most cases.
Handle top speeds of EV's? 200kmph is baby figures
My city uses these airless tires for our lawn mowers and kubotas. They are pretty incredible! Cant wait to start seeing them on cars!
Omg, it’s about bloody time, what’s taking you guys soooo long, I watched this tire years ago!
Well I’m sure that the amount of money they make from conventional tires isn’t at all the issue here…😇
This biggest hurdle with the Michelin airless technology is DOT approval. It required numerous testing and needs to meet standard for vehicles such as weight, speed rating, and must pass safety tests.
Hello. Many people here are confusing this with the Tweel, which is another Michelin similar design but for industrial usage, mainly forklifts and it came out so long ago. its a really high profile tyre and those wheels look custom, i doubt they can be fitted on drop center rims since there is no pressure to hold the beads in place. Moreover, snow and mud with not affect it and they are easily evacuated and ABS and other systems should work just fine because it cant be a functional tyre if it is not transmitting all the forces (grip,brake,steer,carry loads...). Noise is a tricky question.. theoretically should not be higher, all of it is generated in a small contact patch area maybe the spokes can absorb much of the vibrations generated or maybe the absence of an air chamber will produce something totally different,.. hard to tell. Sorry for the long talk.. for the tyre nerds. Peace.
Now my ex can’t stab my tires
cordless sawzall?
chunk of rebar stuck in the side of the tire on the inside face?
I saw a golf cart the other day with these tires. Looks awesome!
I think tire replacements like these will still be a thing with wear and tear, just like tires that haven’t gone flat but go bald, or dry rot.
I think this is one of the most brilliant inventions ever, I hope getting it from testing to market goes smoothly and these tyres are available by 2024 as he said👍
I'd like to see what happens when a puddle freezes around the tire and in these spokes. There will need to be a cover to keep ice and debris out. How long do the spokes remain flexible and what happens when the treads wear out?
Presumably you get a new tire when the threads wear out. Just like tires today.
@@longfang98 : Yes but do they last longer... or significantly longer? Are these more recyclable or will there just be piles of these instead of pneumatic?
These can be used ㏌ warmer climates until further innovation
@@pumamountainlion7777 : Perhaps. There is still debris and small animals etc. We won't know until they try it.
If i can fit them on my wheel i will try em as soon as they come out. Had 2 flat tyre's in 1 week last year both could not be repaired. Had no money to replace them so changed to winter wheels in summer...
What about ice and snow buildup during a Blizzard in freezing weather ?
Good question. I gotta imagine snow getting caught in them would throw the high speed balance off
SMH...
Perhaps a cover attachment, good question.
A little hot water will make snow melt also nothing wrong with slipping a little down the road just hold steering wheel strong..
@@Grandmatabby jesus christ I hope your being sarcastic lol
I'm really curious about sound. in my mind, that design begs for wind (at certain speeds) to cause a whistle or a hum as it travels through the tires(like blowing into a bottle.
plus, I feel like a sidewall is needed because in areas where you get snow/ice, last thing you need is ice or super packed snow in between the "spoke" causing issues with traction/control.
Lastly, how many punctures can the tire sustain before I have to replace the tire. the more holes in the tire, the less structurally sound the tire will be. if they say something like 3, then that's probably not worth it especially when a lot of places patch tires for $15 (or even free here in Indy).
Haven’t these airless tyres been around for a few years now? I feel like I’ve seen these before
I like the questions he poses at the end. Great video and cool concept!
Wow! That’s fascinating
yea, think about how fun car chases are gonna be!!
bruh how has this guy not popped up in my feed sooner he actually locks your focus in lol ( i have adhd ) its hard for me to stay focused lmao but this guy does it so well im unsure why
Cant wait for version 2 when mud wont collect
Several years ago we at Polaris built about 200 Military 4 wheelers with airless tires. I know this because I drove many of them . (just into the truck to load them but still)
I remember them coming out with this like 10 years ago. I am sure tire companies do not want these out on the roads because it would be terrible for business. And money and greed will always win out.
That’s why we’re not as advanced as we should be technologically. Greed.
No need for spare tire ( the fifth tire ) . Does Uptis feasibly apply for airplane to prevent tire blow-up ?
2030: How companies plan to revolutionize the tire industry with this new technology.
*replays clips of the same tire*
I love you intro....You are a literary genius!!
Can't wait for them.
we've waited a decade and they still haven't released them .
Same!
Good questions. I hope those tires are great. I would love to use them.
It's been 10 or 20 years since they have been talking about releasing these tires. Just release them already, because I would buy it.
Us shirtless guys think alike
I asked for it at just tires while fixing my tire. They said it’s not on the market yet and is still under development.
I wonder how they perform when they are full of ice, snow or mud...
In addition to filling with rocks it looks ‘trippy’ in a side skid or even side-sliding.
These tires are about to be $5k a piece
For now at least
Holy cow... It will probably takes 10 years until it can be affordable.
the big question is will it handle sudden brake? or would it jump and out of control
He lost me when he said “a few more years.”
Imagine the police rolling out the stinger but you're on these tires. Lol.
I dunno.. what happens when you get rocks accumulating in the space of the tires, it will basically destroy the support wall and possibly your rims..
im sure they will have rubber side walls once these are mass produced. It looks like this now because they need to demonstrate how it works. at least I think so
I'm wondering if these new tires will be heavier too.
Could rocks accumulate in there? The tire would be spinning... And even so, the maintenance would just be poking the rocks out
@@lmbtcs1879 with the tire flexing like that especially on sharp angle, not sure how well the sidewall is going to hold up over time.
@@lmbtcs1879 yea I hope so too, it looks far better than this that looks like it came off a toy truck.
My tricycle had airless tires. The technology has been around for a long time. ;)
If these ever become viable, I feel like the first car company to adopt them would be Tesla.
Tesla will probably make their own.
@@bababoy91 They believe in vertical integration. They are even looking into mining. People have doubted Tesla every step of the way, so I am not surprised you think that.
@@bababoy91 lol they haven't said it doesn't mean they can't do it... We're talking about Elon ... Won't be surprised if tomorrow morning he comes up with a flying car
The tire sticks to the ground more than a common air tire which results in your car taking much more energy to drive the same distance.
Do your homework cnet! These are a complete Michelin failure 10+ years ago when they first tried to release them and are simply trying to milk the dead cow again. Several auto manufactures were interested until they learned modifications to the chassis where needed, extra tyre weight, couldn't use existing rims, and the cost which is 4x that of a normal tire. Ohh and the real kicker was Michelin wanted to sell them "special" equipment to work on them! Really the only benefit you get is no flat tires and you loose sidewall stability, ability to vary tire pressure for change in conditions, low cost, and low weight of a traditional tyre. BTW they couldn't leave those ribs open as mud, snow, ice, and rocks would create balance issues if they got stuck in there. If this was a good idea you would already see them on race tracks and you don't as they aren't any good.
Some very good questions were raised.
The tweel has been around for at least a decade and I've only seen one vehicle use them in the wild: a lawnmower
I've been watching Brian on CNET since my middle school days and he's just as sharp as then! I think he was the one who introduced me to Ubuntu (probably 8.04) via some ancient video
How many kms would you get from these? They're also NOT for off road use since you can't deflate them.
But there is problem when we apply the breaks ,when we apply breaks at a particular time it will take some time to be stopped at the place where we apply the breaks..The material bends it self and moves from the place where we apply the breaks.
I already can see how dirt and snow will get stick between the supports and making wheel extremely unbalanced.
It's great that there's no more leaks or fill ups, but the tread will still have to be replaced. And I bet you'll have to get the Uptis ones...
Thank you, Gustavo
thank you giancarlo esposito
I would love for these to work, because pneumatic tires definitely have major weaknesses. But, I still have questions: Are they heavier than pneumatic tires? Are they as efficient as pneumatic tires? Are they as comfortable as pneumatic tires?
When it fills with mud or sand or rocks?? Just one rock or anything on road will cause a severe imbalance which at speed would disintegrate the tire. Maybe they come up with a one unit solid wheel tire combo
You feel every little bump. It’s 3 times more felt than a tire with air. I’ve driven equipment that uses these type of tires. We kept popping the air filled tires, so switched out for these. They are not fun to use.
This is a fantastic invention but, how is the police going to forcefully stop the getaway vehicle with spike strips?
I have a feeling that the wheel axels will also need to be made different with a weight shift sensor to further improve the handling.
they have been available for a couple years for ATV side by side s, up to 2x the cost, spacers may be needed to fit proper, my friend having a tire store says he is scared of them, like CROCKS they don't wear out
If you you stretch and contract a rubber band often enough it will break by "fatigue failure". The sidewall sections in this tire flex much more than ordinary pneumatic ones on every rotation, so I doubt that they will last as long.
The first thing I noticed, was the amount of spokes, like on chariots or bikes.
I have no idea how you'd mount these, i work in a tire center, and it's baffling. My guess would be that it'll be a tire wheel combo that you have to replace both every time
What happens if they wear out? Are they recyclable? How long do these tires last in real world use?
I'm hoping the sidewall is covered in the production model. I know it looks cool like that, but it only takes a little bit of mud or snow to get stuck in those fins to make the tire unbalanced.
2 Questions: Price? What happens when the tires will not be moved for 1-2 month?
My biggest concern is how they work in wet or snowy conditions. How does water or packed snow/ice affect that plastic compound their using instead of having a sidewall?
what about test with snow chains on it. I think, in mud or snow it has many disadvantages. What is more, in air tire, you can increase pressure when heavier load is expected, or lower the pressure when needed etc. Here you cannot adjust these tire properties.
These have been around forever. They were even on late 2011 Polaris sportsman 850
