• I Put F1 Tires on My Car
We handmade DIY airless tyres and drove them over 100mph, drifted and over a bed of nails!
Regular tyres have been filled with air for over 100 years. They work quite well, but they could leave you stranded at the side of the road with a puncture.
So, with a very small budget and not a lot of time, we decided to fix tyres forever. But, as with any great innovation, we had a few problems on the way.

So, this is the benchmark. The obvious issue is that it’s filled with air.
And for something so well-developed - isn’t it weird that it can be rendered entirely useless by something as small as a nail - or even a pothole. But before we get to putting our airless tyres on the car - let me explain how we made them.
So the base is a 14’ steel wheel from a Ford Mondeo, then bolted to the outside are 15 lengths of PVC Fresh Water Pipe. And I know we’re not NASA - but it actually worked well. It's our unique Puncture-Proof Tire System! Using only pvc pipes, nuts and bolts to fit all together.
Now for the clever stuff, these smaller ones are our anti-vibration pipes - to make sure things weren’t too bumpy. Then the grippy bit - this is just the tread from a normal tyre - wrapped around the outside. Then to keep it all together, we used over 300 nuts and bolts.

Dude that thing looks amazing with those f1 tyres
First video to see an airless tyre do a burnout.. congrats boys and girls
What this proves is that different filaments on the 3-D printer for the actual tire concept is needed not just the same rubber filament for all the different tube positions.
All nuts and bolts aside.., if they were to use different strengths of different filaments to make the different sizes of tubes in the concept 3D printed tire... it should work
Use a flexible spray foam to fill inside the pipes to dampen the sound and lock the nuts and bolts.
Speaking of “pot holes”, when repairing asphalt there is a heat pot that melts rubber to viscus enough to pump into cracks. I think using one of those to finish off the tire by filling all gaps, will be a way to actually manufacture these at a reasonable cost. You can use recycled tires to melt down to further reduce your costs.
If any of that helps save or make you money, I need a back hoe.
Good luck
The most obvious conclusion from this video is that I need a Caterham.
That's always true.
Are you saying you didn’t know that BEFORE seeing this video? If so, sorry for you.
@@Nevir202 I’d rather get a slingshot
@@OVERDRIVE.studios you got this idea from the US military, and just changed the design A smidge
@@resenddelete6820 caterhams were first based on the lotus 7 though
Instead of nuts and bolts (which will invariably come loose with vibration) have you thought about tension cabling? Like using a steel cable woven through multiple peices of pipe and attached through the wheel rim. Then with wrapping the cable through multiple times before going through the wheel rim again, such that if it started to come loose, there would be a gradual degredation.
It would have just torn itself to bits ! Like a cheese slicer.
or easyer: glue?!?!?!?
You're about back to steel radial tires if you're doing that much cable weaving. The idea is trying something fundamentally different. A hot melt adhesive would be an interesting approach that resists vibration, provided surfaces are properly prepared and compatible.
Or just use lock tight on the threads...
@@a3r797 Yeah, but then good luck getting them off if you need to fix or adjust the tires lol
This is so Old Top Gear I love it, the humour and everything so much like the testing of the Hammerhead Eagle i-Thrust, ambitious but rubbish-ish (as they were decent for 1st try tbh)
If you like this sort of stuff recommend CarThrottle. Also HatFilms who very rarely do car stuff they are very reminiscent of the classic Top Gear trio.
@@fsfaith I’ll check them out. Thanks!
Your username and profile pic don't match
Now we need a British Stig. Wait...
Yep, strong ambitious but rubbish vibes going on here 😂
Extremely suprised with how rigid the wheels where!
Love projects like these. Yes it was vibrating like crazy but still.. it did what it was designed for!
As a first test, that was ridiculously successful.
Thanks Paul! It surprised us too.
Amazing video! I'm hoping one day airless tires will be the norm.
I'm sure i'm not the first to point this out, but 99.5dB is WAY more than 2x louder than 90db. Assuming that your measurements were taken at the exact same distance in both scenarios, its roughly ~9 times louder (8.91 times louder to be more accurate).
With a standard reference sound intensity of 1E-12, the sound intensity values you end up comparing are .001 and .008912509 etc etc

I'd say that was an unexpectedly good result! Solve the loose bolts and rounding, figure out a way to dampen the noise (sidewalls probably, even if they're mostly decorative in this case), and that should already be a pretty good tire.
This was honestly a job well executed guys. Wouldn't take much refinement to make them work honestly. And glad to see Scott back as well it's great woth you two together.
Can you test acceleration and breaking compared to regular performance tires ? The usual principle is that air allows deformation required to get more (or optimal) adherence with the surface, more contact area. I'm curious about that principle since you need more rigidity in your concept to maintain integrity of the tire to lateral forces, it should adversly affect the contact area with the pavement. Let me know !
I guess with airless tire a softer rubber would be needed to make up for that? You can kinda see the lack of grip when they are driving around.
You should tell about this channel on driver61, i actually found this accidentally, it's so cool to see you 2 car friends having the fun of your life. I myslef can't wait to do car stuff when i growup 😀
Literally watched driver61 for like a year before I realized this channel was a thing
Literally just saw a post (from a few hours ago) and came here to watch this amusing video.

In case you haven't considered it yet, some (probably most) of the noise and vibration is caused by the seam where the tread meets. If you could find a way to leave about an inch of sidewall on both sides and mount that on your design, the noise and vibration should be closer to regular tires.
Actually, I thought the whole process could be improved by gluing the "drain pipes" inside a regular tire, )shortened some to fit), and then letting the sidewall "skirt" the wheel. This does away with the tread seam, which is a weak spot, and the sidewalls would prevent the tread from wandering right and left when gripping the road. It would be challenging, but this DIY is very feasible.
The first job I ever has I use to retread tires. And the two ends shouldn't be connected by a straight flat cut. You make a long diagonal cut. It gives more surface area for adhesion and it won't deform.
@@JohnSmith-ft2tw fuckin oath I think you’re onto something
Also I'm sure these things aren't balanced in the slightest
@@zachsmith1731 That's easily fixed with a few more M6 bolts. lol
Suggestion. Here in the US, and I believe in most racing circuits, they have this thing called a "helmet". If you think your tire might come apart and start spraying nuts, blots, and tubing maybe you should invest in a couple helmets. Just a thought. Great video guys. Loved it.
this really brings back the top gear experiments vibe, hope you guys would do more like this
I think we can all agree that the Caterham is just THE perfect test bench for projects like this.
Very entertaining, keep it up!
I'm suprised how well these worked, I was expecting catastrophic disaster almost immediately 😂😂
One improvement I can see pretty quickly would be to use some sort of PVC glue to hold everything together instead of bolts, also don't cut the thread and join it again, that's probably contributing quite a bit to the vibration and adding another possible point of failure...
Did you try red thread locker? Could help with the bolts coming apart
They were nylock, but we should try that.
@@OVERDRIVE.studios maybe also try use some assembly compound....orrrrr....to reduce weight and effects of rotational forces increasing the g-force and therefore the effective weight of the bolts, why not just try and stick them together with epoxy?
Maybe try pack out the outside of the wheel using space-foam held on to the piping with something like a tightly wrapped Kevlar sock before you put the tyre on?
ChrisFix liked that
@@yigithan3713 that's exactly where I got to know about this things years ago
May be cut the pipes in 2-3 sections and overlapping the position, so it won't be so bumpy?
that noise issue would fix the noiseless safety issue of electric cars, which normally make no sound leading to accidents
Wear freaking helmeeeeet we want you for tomorrow as well
The next Caterham is having a windscreen at least!
Tire tech has honestly become very developed. Tires are designed to flex to give a dynamic contact patch, and flex sideways a bit for slip angle. They also retain heat for sport driving because they hold the air in. These might be great to defeat spike strips from annoying cops….
Me in Africa watching Scott call a road a pothole...🤣
You guys are on to something big... Thanks for the video
RSA!!!
Seriously. They didn't even go airborne. We have way worse pot holes in America.
Michigan feels your pain, friend. Ice and plows kill the best of roads.
watching this in middle of nowhere (somewhere in finland) our unpaved roads are literally pothole with yumps, that is sometimes used in rally.
5:10 you should see the road condition in India. It is basically offroad terrain compared to this
So you're saying you want a set?
Tru AF
@@jamesengland7461 well sets* because the amount of uhh lets say perfectly engineered potholes are astounding in India >
@@jamesengland7461 prabably when I have a driver's license XD
@@sriharidesai7606 True
When putting tread on a tire don't make it a straight flat cut. You need to make a 4 inch... or a 10cm diagonal cut on both ends. It provides more surface area for adhesion and it removes any deformation at the seam. You could make it longer than 10cm, it's just a good amount of surface area with minimal waste. And I'm totally going to try and make these lol. Awesome video.
Those had no right to be so durable.....
"Lets here those ponies gallop"
Comes out with these, and all you hear is clop clop clop as it goes by.
I'd die.
We've been using airless tyres in the outback for decades. If you get a flat and don't have a space, do a small cut into the sidewall of the flat and pack it with Spinifex grass until you can't squeeze anymore in. Will run for 1000's of km's and save you life.
And what do you seal the cut in the tire with? Will regular duct tape hold it?
@@MishraArtificer tape, rope, garbage bags, vines, whatever gets you home. (Wrap through the spokes and around the outside, not just along the side of the tire, even with the best tape, unless you can seal the inside like a solvent-based bike tire patch.) It just has to be enough to work until you can do better. If it fails, you repeat or try something else.
Why not use closed cell foam cores or solid tires, and softer shocks?
Just two lads having an absolute blast!
Every 3 dB doubles the sound intensity so 9 dB more is 8 Times louder!
Mad respect to the Enginerd for not just making those but also going along for the maiden voyage 👍 Epic!
Did you try threading wire through it? I think that would be less likely than bolts to fall out, and if it's properly tensioned, it could better spread the throughout the whole structure.
How would you make it less bumpy?
@@senordinkus more forgiving tubes held under tension in a more oval shape maybe?
@@zachmoyer1849 It'd look like a flower lol. I'm not an engineer, but it'd certainly be neat to see them do that.
@@senordinkus the lotus eleaf tire lol
Maybe consider putting that solution inside a tyre casing, then on the rim. That way it is all contained inside the casing, lessening the chances of it coming apart. It also means a continuous tread that’s not held together by screws. Any tyre could then be converted to make us of this.
Yeah that was my idea as well. It would then act as a large run flat ring. Dump some water beads in it instead of air. and you could still call it airless. lol would be heavy with water beads but would work. Also wondered why they didn't just cut the sidewalls out of a tire. that would leave a single tread ring to fit ultra snug(example you have to use heat to get it to fit. like a steel ring on a wagon wheel) . instead of a seam.
Would you put these on your car? I think with some work - these are *THE WAY FORWARD*
Yes. Many kilometers forward. More than can be counted on both hands.
You should do some timed laps and see what the difference is between a normal tire and these.
not literally this tyre but yeah any airless tyre prolly
@@sriharidesai7606 Nah
But sometimes I need to reverse...
you could fill the pipes and gaps with something like Construction foam so you dont lose bolts and it also could help with the roundnes of it and maybe use something like flexseal at the seam to reduce the noise it makes
This feels straight out of MythBusters. Good choice with using such a light car. But as soon as you mentioned drifting, you guys should have on some helmets.
like the idea of using easily source-able replaceable components. Obviously needs some tweaking such as a better retention system to keep it together and the tread on.
Reinventing the wheel, I see
What a great idea. However, there is no freaking way I would get in the car with you going that fast with no airbags or helmet. Lol. You guys are nuts.
This was absolutely BRILLIANT!
Great fun! I just wish you'd made a longer episode on this :)
Keep it up!
I'm a drainage design engineer and I so wish you boys would have contacted where I work for advice as there are definitely improvements that can be made with some better pipe choices. I reckon I could remove some of the bumpy ride from these tyres.
Airless tyres are great, but they need sidewalls like normal tyres to look better and to prevent all kind of stuff getting into those holes.
That noise test wasn't a fail! Every 10db represents a doubling in the actual volume of the sound, so jumping from 90db to 100db is a hell of a lot more noise
Honestly, if you can create a mechanism to keep the tread from swaying, and clean up the plastic areaa, thats a good design. You guys should make a bigger version and take it off roading
just leave an inch of the sidewall and figure a way of getting them on without cutting them in half haha
Tread "sway" is part of tire design - the lateral forces present when it occurs is part of the reason it's taking so long for these to come to market.
Having a sidewall on each side instead of open sides would solve this.
If they can be made cheaply maybe selling them as an option for spare tire or upgrading them for full out driving would be great like making the plastic parts one unit instead of separate tubes this would allow you to make it round this more stable could go way faster and then attached rubber on the outside could be one solid ring and the tread would be able to take more sideways pressures if it wasn’t flat totally but a small sidewall to enclose the innards not thick at all but it would eliminate air and last the same as it’s air having counterpart or even using a regular tire with a thinner sidewall having your idea for the tire on the inside to just eliminate the air aspect it will allow people to use them much longer and even start to retread the tires like they do big rigs making it cheaper in the long run the hardest part would be designing that circular structured plastic to be installed before and still able to put tire on rim or have the rim itself be able to be taken apart and reassembled so that you can build it opposite of the current process assemble the tread portion with your pipe parts inside the tread /sidewall unit and then assemble the rim part last the design of the inner rim would make it possible to utilize this on any vehicle as you could have options on each peice making it interchangeable for many reasons like custom colors shapes and technology that can be added to suit everyone and every vehicle the only real problem is designing the product in a way that makes it very inexpensive for you to make it and low enough for customers to justify changing from the regular rim to your product you could make the initial purchase at a much lower gross profit margin than the customized parts that are available this way the product will be available to lower income ppl that need a reliable option and the customer that has a large income and can afford to make a fully custom tire replacement is the one paying the higher margins for a unique product that is exclusive and would be charged as such but if the base model so to speak would be affordable and have multiple reasons that it is the sensible thing to do it would undeniably be competitive with regular tires and would have less rubber no air hopefully similar handling and price unless it’s cheaper and have a far superior lifetime on top of being retreadable but still appeal to younger and all other crowds for its price and options so the low rider guy could pick whitewalls the racer would get streetslicks with the lightweight additions the outdoor guy gets large truck all terrain options and gramma can get the basic model or that single mother with kids can afford to buy the basic version eventually opting for the matching color of the car on the inner setup when the kids get older and are ashamed of the boring rims this could be done even with todays tires and rims but these would be one wheel upon purchase unlike rims and tires but would have more peices that can be replaced for artistic or functional reasons one could do collaborations with fashion designers or anyone like rap stars tv stars etc etc etc and could offer new attachments when the current ones sales die down bringing and sustaining steady sales with endless unique variations and one off auctions artist designs for every big and small niche groups icould go on and on as you see but this idea is beyond good if someone takes it seriously and invests gets investors and a good team to perfect and create a functional product
Here's where the beginning of mass production falls on its face:
Press release: due to a pandemic of shortages of blue and black pipe, nuts and bolts, we regret to inform you that we will not be able to fulfill your order for an indefinite period. Thank you for your patience.
400+ USD per tire for something you'd change every year or so. Perfect example of why airless tires aren't taking over the industry, but are still worth conceptually approaching until they're cheaper to produce.
These actually seem to be quite solid
Well liquid or gaseous tires wouldn't work, so they better be
Mold the rim as one solid piece and you'll need shocks like on a dune buggie...
3:26 As a Mythbuster would state, " ...well theres your problem."
I love this gents. Please keep up this great content.
The splice joint for the tread may work better cut at an angle or a scarf type joint to spread it over a larger area.
I think I'll stick to standard tyres unit they're perfected, good try
I can't imagine the pressure on the suspension with such tires. Let's assume for a moment that a robot is driving car on such tires so there is a question: How long will the suspension last until it's totally out of order? Like 500 kilometers or so? I don't expect the robot to survive either...
Charming sound, the unsprung weight reduces as you drive, withstands your industry- standard bed of nails, immune to imperceptible potholes; what more could you ask for?
Mileage, these didn't last long enough. Needs more prototypes and design corrections but these did hold up well for the first attempt
fill the gaps between the tubes with spray foam insulation. reduce nut and bolt loss and vibration maybe?
A great idea, except in terms of aerodynamics and debris.
And expense. And reliability. And ride quality. And noise. And grip. And weight.
So, yeah. Nearly perfect!
But the unsprung weight decreases as speed increases, this is a great feature for performance!
It's just a rough prototype
could you use a metal wire through the bolt holes to hold them together instead of bolts? this could give some rigidity by pushing the pipes into the rim, and also lose some weight. maybe also try waterhose type pipes in place of the small ones? say, hydraulic hoses? those are quite good radially, you wont collapse them easy
Anyways.. I believe your design is much better take on the airless tire than Michelins idea using all rubber. Though, you could use a rubber coating on each of the pipes to absorb more of the vibration and impacts in the wheel itself. I also believe having a little lip on the outer diameter tread to the inside and outside of the tire pad would help with keeping the internal parts in while cornering as it'll dimple at the more force, keeping the inner wheel together more in unison. Like what you could had done was kept some of the sidewall of the tire you used as a part of the tire to keep the smaller light blue pipes from slipping out. I was surprised this set up held up at 100mph, and was able to take corners without falling apart, I mean aside from loosing a few nuts and bolts (could has used large rivets instead), you just had horrible vibrations probably due to the seam in the tread and no real dampening or balancing in the construction of the wheel. If there wasn't a seam and you really thought about balancing each wheel, it may had not been bad at all. And you probably could had went faster in that straight away. Whats crazy is that Michelin didn't come up with the initial design.. the original design was created in the 1930's was called the Elastic Tire. Similar idea of what Michelin is using now, but it has it's flaws as it gives away in corners and it's not rigid enough for highspeed cornering. Your design takes on a different perspective though, rather than using all rubber, just the tread itself is rubber, and the inside of the wheel is plastic and steel. Mind you that your wheels aren't really balanced, and there is a seam in the tire cap.. but overall you could improve this design and make it a pretty rigid tire and wheel if you put your mind to it.
this is genius. cant wait to see ur developement
This is really sick, I love this channel and seeing all your side projects. Keep them coming!
That was a very thorough scientific experiment, I enjoy it
These are so cool, and it would be pretty cool to see a set for motorcycles and dirt bikes🤩
that would be pretty dangerous.
yes i drove a old cruiser and got a puncture and the tire separated from the rim and i completely lost control over the rear end, im lucky to still be alive.
The nuts and bolt assembly makes me seriously anxious as they can easily become deadly projectiles
Brilliant fellas! great work!
Thank you, we loved making this.
@@OVERDRIVE.studios it shows, looks like your having a riot! 😊👍
There are lock nuts with nylon inserts that will prevent them from coming loose from vibration.
These would probably be better as an inexpensive insert for tires to keep you going at reduced speed in the event of a flat tire. Making them injection molded and somehow attaching them to the rims.
if you just put the drainpipe core inside a regular tire with sidewalls intact for extra support and most importantly don't cut the thing, it would probably work ok.
Something like this definitely has a use, even if not for passenger vehicles.
Love it when someone is willing to try out an idea & have fun in the process. Great job 👍🏻
Airless tires are used for commercial use like building/demo vehicles, forklifts, etc. Though forklifts use special tires that have sideways rotors and separated differentials so you can move horizontally.
should've used some loctite on those nuts
To me, all those bolts and nuts look like potential bullets when the car is traveling at high speed. 1200 bullets from tires alone.
A real killing machine ;)
This would actually be a great idea for a reusable spare tire that is light weight
THAT WAS FINE… OOOOOOH!
That was fine… oooooh
I’m crying 😂
Love your enthusiasm but tired with air in them are much better even though you can get punctures.
Great idea for a daily, not so sure if I'll put them on my Caterham 😀
Have you ever tried to compare the with air and airless tire in breaking test? How long its take before the car is stop. With load and without (maximum load of the car)
In poland are more potholes on "normal" roads (all except highways and high speed roads) then meters of asphalt
Needs one piece tread and better balancing for the first couple easy upgrades. A few more R&D generations and a multimillion dollar manufacturing setup and you could be in business!
I think if your little blue pipes were a size bigger, it would even out the roundness a lot more. Also, you should have put locktite on your bolts when you put them together.
It’s actually about 6 times as loud. Every 3dB is double as loud as before.
Instead of cutting the belt of the tire, what may work better next time is to try to insert the hub and pipes in a slightly compressed state. That way in addition to keeping the belt and tread intact, the wheel will have additional mechanical retention of all it's elements. Just a thought
Oh god how awesome is your invention! Are you shipping worldwide? ;)
I'd like to know the rolling resistance you get from these tires. The more area you touch with your wheel, the more energy you will lose in rolling resistance.
One nit pick: +10 dBa means inrcreasing loudness by factor ten, not two. (precieved loudness is a different thing though)
You literally destroyed tyre sales globally and smack big tyre company stocks, good job.
3:15 That's actually 2*2*2 = 8 times louder!!! (dB is a logarithmic scale in base 3)
Tony Stark built the suit in a damn cave
Upgrade idea. Replace the tubes with ones made out of the new 2D material from MIT. It's lighter and a whole lot stronger. And can be printed.
Well built. Now you need a wheel sized extrusion and dye to get something in two or three pieces that can be bonded rather than bolted.
Wow, you guys just did a Mercedes Porpoising simulator, nice.
Since the Michelin airless tyres i've wondered, in certain conditions. Wouldn't dirt and gravel get inside the tyre and cause balance problems on the long term?
Between mud, gravel, and water, and manufacturability, there is a reason why airless tires haven’t taken off.
I think if you would of used a perfect sized tire that you didn't have to split and locktight on the hardware, they probably would of held up alot longer.
Reminds me of putting playing cards on bicycle wheel spokes . Live . Love it took me back 60 years. Thanks guys .
DON'T EVER GROW UP. JUST GET SMARTER.
GOD BLESS YOU.
It’s really funny at 6:22 when it says easily 300mph lol
$400 for 1 wheel when I had 4 brand new tires, an alignment & wheel balancing done for $650 over the weekend. Makes sense 🤣
i love it really. good job guys
Crude not much budget but I think your headed in the right direction especially if you encased the parts inside the tire you could lose the hardware..
For noice cancellation u could put somethings inside your tubes ig it should solve n in place of tubes u cn use hard rubber
That's a set of brass ones using that vehicle as a test bed!!!!
