We put F1 tires on my road car!
• 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.

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

@Snackerbater1 Год назад

Use a flexible spray foam to fill inside the pipes to dampen the sound and lock the nuts and bolts.

@chadachwilliam5515 Год назад

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

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.

@steve.roadcap 2 года назад

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.

@JohnSmith-ft2tw 2 года назад

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.

@Arrowed_Sparrow 2 года назад

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.

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

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.

@Ding_Bat 2 года назад

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.

@non1503 2 года назад

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.

@fieldo85 2 года назад

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.

@@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.)

@MAGIeYUU 2 года назад

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 !

@avixs1543 Год назад

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.

@jurchiks 2 года назад

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.

@NeedANameWithoutNumbers 2 года назад

Seems like a fantastic success for a 1st build. You're definitely on to something here. If you happen to do a revision maybe leave a little bit of sidewall as sort of a bracket to mitigate the tread from sliding sideways. Also if you can do it without cutting the tread and creating a seam I'm sure it would hold tighter. Either way that was a really nice idea and if I had the funds and tools I'd be trying to replicate this to apply to my normal daily driving.

@jaixc 2 года назад

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.

@124c41p 2 года назад

High performance radial tires have their plies wrapped in a spiral manner creating a single seam that wraps itself around the entire circumference of the wheel rather than a single straight cut across the tread. Think of peeling an orange using a single cut without allowing it to break or even a corkscrew. Adhering the tread to the body of the wheel consistently and in a manner that resists both lateral and fore-aft force appears to be something you've already solved. You're almost there!

@robertlane6431 2 года назад

What many don't realize is that making an airless tire isn't that difficult, but making an airless tire that works in all climates is far more difficult. Very cold weather is the biggest issue as I understand it because it makes the components brittle and far less resilient. Heat also seems to pose a problem since it softens the components causing them to perform differently and they compress more than they should. But don't get me wrong, I am not disparaging this video because for a DIY project they did an amazing job. I am only pointing out the difficulties in making something like this for mass production. It's also my understanding that airless tires seem to wear out much faster than conventional tires due to the constant flexing and rebounding of the inner structures. I do think they are the way forward but they are going to require alot more development before they are truly viable against conventional tires.

Even with simple plastic tubing you have demonstrated this whole concept to be viable.

@barms9768 2 года назад

Any tire can go over a bed of nails like that. It's an old trick, a dense "bed of nails" covers enough surface area to support the weight without puncturing. 4:12 you can see the tire appearing to float across the tips of the nails, not even coming close to the board in the area where there are nails. Had the nails fully punctured, the tire would have touched the board, especially considering the exposed parts of the nails were barely longer than the thickness of the rubber itself.

@iainburgess8577 2 года назад

Potential improvement. Locktite. Glue (especially tread to pipe) Speed holes or strategic slitting of the pipe sections would allow them to deform more. Naturally w some loss of durability. Air/sound shields on the sides, which would also return more standard tyre aerodynamics. Possibly some structural improvement. Possibly a foam rubber to fill between pipe sections on the outer rim, then ground back as a balancing process, before tread laid over.

@Arrowed_Sparrow 2 года назад

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.

@RunAzazelRun 2 года назад

Ok probably a dumb suggestion, but couldn't you just take a tire fill it with the pipes in the same way (maybe glue them instead of nuts and bolts so you could pile them without falling) so you could keep the sidewalls of the tire which might save weight without all the hardware (or as much if you did 1 in the center rather than 1 on each side), cut down on noise since the air wouldn't pass through them, and give you more stability side to side for drifting. Not sure it would be better but if you ever try a version 2 maybe it could work.

Try this instead: Testor Corp Cement Glue - Nothing beats a quality model cement for joining ABS plastic or polystyrene plastic, and Testor Corp’s Cement Gluemakes the job even easier, thanks to multiple precision tips that ensure accurate application. Toluene melts the plastic on application and polystyrene welds plastic objects together once the toluene reaction ends. It sets within a minute of application but begins reacting on contact: Be sure to place pieces correctly to avoid visibly melted plastic around the glued area. Note: Always use in a well-ventilated area due to the cement’s strong chemical smell. Also, cut the sidewalls off the tires, then heat them up and stretch them over the plastic tubes instead of cutting the treads.

If I remember correctly, an increase in 15db = 2x perceived volume...so you guys add 9db increase which is almost 1.5x noisier. Great test guys, made me smile!

Honestly, when we are living in the post apocalyptic wasteland and new tyres are impossible to come by, this is gonna be one of the most useful videos on the internet.

I like that these guys are engineering but they are totally just having fun. This has to be the best kind of job out there

I enjoy these videos for the sheer fun the boys are having playing with grown up toys.

"Lets here those ponies gallop" Comes out with these, and all you hear is clop clop clop as it goes by. I'd die.

The thermal load of the splines flexing per revolution will be a problem. Sacrificing the contact patch to solve it would be stupid. Airless rubber spline tires would probably handle side load better and more reliably than "air-ballon" tires. You need a stiff rim to not interfere with the brakes. I don't see any rubber hybrid rim handling that part, not even to mention the heat of the rotor.

Just two lads having an absolute blast!

my first thoughts were: you should cut a seam the width of the tire. if possible you should only cut off the walls and leave the tread part completely intact. it also could use some fill material between the rubber and tubes to make them more round. another issue that needs solving is the amount of bolts in them, maybe look for a way to produce the infill part in one piece, if that's even possible.

Gee, _only_ $367 a wheel? Good god I feel like I could buy almost an entire set with that amount of money lol In all seriousness, if those wheels basically became the last wheels you ever needed, $1500 for a set would be a steal.

Hi from South Africa - Just what I need for my garden zero turn lawn mower as I am fed up with punctures. Well done guys

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.

I was just reading up about these (probably why the algorithm fed me the video), I think heat transfer is another potential issue in the development of airless tires, air is a fantastic insulator of heat so naturally with pneumatic tires there isn't much material to transfer heat into the wheels, brakes, other bits in that area (I'm no mechanic lol)
