How Will A Car Perform With Square Wheels? | MythBusters | Season 8 Episode 20 | Full Episode

Always love Adam's reactions to disaster. "Whoa, Whoa whoa whoa! *Breaks into giggles*"

[@_Aly_00_]

17:13 "Somethings dreadfully wrong!" Yeah we can see one of the wheels on the ground in background behind you 😂

[@bsm130]

they didn't torque the lug nuts

[@WhitzWolf92]

@@bsm130At the risk of me just missing a joke... We don't know if they they torqued the lug nuts or not (no, it wasn't shown that they did, but this was not either host's first time turning a wrench and that's absolutely something that would be cut for time on TV), but it doesn't matter. They striped the threads clear out of the hub (see 17:37 - 17:39, those are not supposed to be smooth holes), at that point the lug nuts are totally irrelevant.

[@keithrice39]

I love how Jamie is slowly working through the engineering that lead to caterpiller treads (which are basically one long square wheel that also has the advantage of round ones). Seriously, no joke it's impressive.

[@fredhurst2528]

I don't think there was really anything to be confirmed, they just wanted to drive a truck with square wheels for the fun of it.

[@xSARGEx117x]

​@@BillyBobThornton245 because Jamie, for how much he was part of shaping my childhood, and I still like him... Is a stick in the mud. He's the boring twig in the mud in the hole in the stick in the mud. He's extremely level-headed 97% of the time. His "this is the most excited and energetic I've ever been in front of anyone who isn't my wife" is Adam's baseline. They're just too different, two incompatible people. And that's okay. You don't have to be everyone's friend. They could work together. They brought joy to many. That's all anyone could ever ask for. I do like when "friends on camera" are actually friends in real life. Back around 10 years ago I asked Nathan Fillion if he and Alan Tudyk were friends in real life or ever hung out after Firefly ended. He told me they had caught Game of Thrones together the week before.

[@barneyisabro]

@@BillyBobThornton245 Only partially true. Jamie is much older than Adam, and Adam is on record as saying their relationship is more mentor/mentee and professional coworkers than friends, hence them never hanging out. They have a lot of admiration and respect for one another, it's just not that kind of relationship.

[@xXxJustCallMeM]

So much torque it twisted the chassis off the line.

Thanks for finally doing the full episodes!!!!!!!!!!!!

[@Lagbeard]

It would be theoretically very possible to get a smooth ride out of square tires... But the speeds and forces required probably can't be provided with any realistic engine.

[@justanoman6497]

The lack of continuous contact would mean little to no steering I imagine.

[@samuel010898]

@@justanoman6497 or acceleration. The faster you go, the more time the wheel spends airborne. That’s probably why it started drifting as he tried to push it faster, with the lighter rear end drifting first. Not to mention it definitely completely trashed any unsprung parts of the drivetrain, the brakes falling off was crazy lol

[@aj7419]

sure... ...maybe if you lived in a different universe where physics are completely different it is absolutely practically (and for all intents and purposes, _physically_ ) impossible

[@tombattraw1410]

The real trick is to get a road composed of curves that fit the square wheels

[@pleappleappleap]

Having a square pneumatic tire might help.

[@LazyLemming2]

Turning the two cars might have worked better if there was a little bit of give/flex in the connection between them. Similar to a trailer. If two of the pieces of the cars were to wrap or hook around each other, there might be a little bit of a hinge.

[@Dimon12321]

44:30 Adam: It's like one of those "What are we doing?" moments Jamie: I think we have more of those moments than we do the normal ones LOL

[@arthurmartin4616]

Being one of the emergency workers on site of mythbusters shoots must have been so surreal. On one hand, great for fans of the show. On the other, it must feel weird using the hose on a street so they can try to drift over it.

[@Eguzky]

[@yervler]

Jamie looks like Doctor Eggman at 17:40 lmao

[@davidmccarthy6061]

Common experience, with round wheels, that higher speed over bumpy terrain makes it feel smoother. Still tough on the suspension though.

[@AleksiJoensuu]

I think Mythbusters tried this myth once, too.

[@pyrho1]

Thank you so much for posting all of these full episodes

[@HardxCorpsxKali]

31:33 I have no idea how I never knew this as a kid but 100% the cars would’ve worked had they been able to fuse them together at the very front. The pivot point would’ve allowed the cars to angle while staying connect but the way they have them combined it’s completely rigid.

[@xpndblhero5170]

Now I'm curious if octagonal wheels would work better..... 🤔💡😃 😂

[@Psychic42]

Yes. The more vertices you have on a regular polygon, the closer that shape becomes to a circle. You can think of a circle as a regular polygon, with an infinite number of vertices. so a pentagon would be better than a square, a hexagon would be better than a pentagon, and so on a so forth up to an infinite number of sides/vertices. There is also a cool video about designing a road that works best with a square wheel. kzbin.info/www/bejne/rnjbhIewlq53ac0 really fun video to watch and think about

[@justanoman6497]

@@Psychic42 I mean in the real world there is no such thing as a perfect roundness, they are probably just a couple hundred thousand sided polygons already.

You're thinking in the wrong direction my friend... We need Triangle wheels

[@heartofdawn2341]

Square wheels would be an utter nightmare on ice or in the wet, or when going around a corner. And you'd need to keep all the diffs permanently locked so they don't end up out of sync, which only makes everything else so much worse.

[@KingSvenDeluxe]

Square wheels are the norm in Canada, that's why Jamie likes them.

[@bobkin611]

It also helps that they only have one road, low maintenance. No wonder they’re so happy

[@tomplayz4209]

I say for the date night 90º turn if it was repeatable and consistent (turning left would always turn right) it should be confirmed

[@names_are_useless]

Are you a real person?

[@josiahsimmons9866]

It did remind me of Cars, "turn right to go left" and whatnot. I wonder how it could have been if they chose to test it a few more times. Though, maybe they did and it just didn't make the edit!

[@JediSentinal]

Yeah, if they can pull off a 180 you could use the same technique to pull off a 90 with some modifications. But that's getting into the weeds for an entertainment show lol.

[@cooljammer00]

I could have sworn there was a bit in this episode where they showed a car model with square wheels traveling on a road with big divots in it where the wheels fit perfectly in between so it was actually smoother than round wheels, but I can't find it now.

[@squidwardo7074]

I think it was on a vsauce video called "the brachistochrone" or something like that

[@andrewirving3982]

I remember it being an animation

[@samuel010898]

Some guy made a big video about it that became popular, but the problem with those designs (aside from needing an appropriate pattern to drive over) is that they don’t maintain constant velocity. This is easy to visualize; when the corner is down, the wheel has a certain effective diameter, but when it’s flat and the road comes up to match, it’s touching the wheel closer to the hub, so the effective diameter is smaller. So the odd shaped wheel maintains contact with the road, but it wouldn’t drive smoothly. Now having said all that, I’m going to try to find that video and see how wrong I am lol

[@Daniel-mk6ed]

For the square wheel truck wouldn't the differential change the offset stuff they were talking about unless you locked the steering or something

[@JDrapic]

That truck is the funniest thing I've seen in a long time. I am cackling! 😂

[@bloopasonic]

Many years ago, I was woken up in the dead of night by a very talented stunt driver conjoining his car to one parked on the side of the road. The cars were so expertly conjoined that all of his attempts at driving off were foiled by his wheels just spinning. It did not stop this fine gentleman from just keeping it floored. By the time the cops arrived, he was grinding the asphalt with his rims. The stream of sparks lit up the night sky.

The 1900s tire investors would be like "We tried it you dummies. It won't work". 😆

[@HardxCorpsxKali]

37:22 they mean they both turn the wheels in the same direction. If one driver turns left the other driver needs to turn his wheels to the first drivers right. Which is also left for the opposite driver. 😂 so they need to turn the same direction.

[@Splarkszter]

This square wheels episode is exactly why I loved mythbusters.

[@ArtThingies]

In a lot of ways, the "square wheels" principle for soft ground conditions is in use often in the form of tire chains, although not literally square.

[@teeheebrah6584]

I miss grant

[@Bobal27]

26:43 I’m curious, did they try right pair offset 45 from left pair, or front pair offset 45 from back pair? Or was it just assumed that those wouldn’t produce better results than diagonal pairs offset?

[@Helpline5815]

Anyone else think of the Island of Misfit Toys on this? The choo choo with square wheels on the caboose? This is the island of misfit trucks and myths. 🤣

[@JonGamer16]

square wheels would theoretically drive smoother on specially grooved terrain that complements their shape and size, but it would have to fit perfectly

[@MyDarkWorldX]

really enjoyed this episode! the concept of square wheels is just wild. but honestly, i think they could’ve explored more practical uses for different wheel shapes instead of just focusing on the square ones. like, wouldn’t it be cool to see how other unconventional designs could impact performance?

25:23 Soooo funny 😄 how well this worked so quickly, love it :D

[@mattdaddy_888]

even with the square wheels offset 45 degrees they won't stay like that permanently thanks to the differentials. That's why the first test went smooth but then rough again until the wheel fell off because the differentials allowed the orientation of the wheels to change independently from the other wheel on the same axle. Maybe try welding the differentials.

[@heartofdawn2341]

This is a myth someone could easily push further on a small scale. Get some 2wd and 4wd RC cars, race them on a track through different conditions, and then see how they compare with square and round wheels.

Idea! Connect 2 cars together with the steering and acceleration combined, then just use one car to accelerate and steer both.

[@silvokristensen9982]

[@pathutchison7688]

Octagon wheels could lead to an automotive revolution 😂

[@CarAudioEnthusiasts]

ok so, the tire falls at 9.8 meters per second, SO at Some speed, the wheel would be rotating fast enough to Beat gravity and go corner to corner. the PROBLEM is even once it was totally smooth since only a tiny portion of the WHEEL is making contact with the surface, AND its Impacting each time, there is a total loss of traction both forward and side to side. so its essentially floating. this brings the other issue, once it STARTS floating, its no longer able to maintain speed. its like trying to take off in a wheel powered airplane.

[@hizzy70]

They obviously need to try triangular wheels that will dig into the dirt better. Lol...

[@yaksubway9254]

Anyone know the music at 24:38 ?

[@thefreedomkiwi]

He's actually wrong about why it turned right, when cars drive forward the wheels in the front do the turning but when you drive backwards the steering is reversed with the taxi being front-wheel drive and the back wheels having near no grip it's essentially just the sports sedan driving in reverse but with the taxi front wheels doing the job of the sedans front wheels

[@TheChellybean85]

That squared wheeled truck be twerking! 😂

[@SantoshBansal-c2t]

Now I am wondering if triangular wheels would also work.

[@seanfoltz7645]

It actually looked like the tape was holding the square wheels back the first time.

[@Galaxius2117]

I think the only thing square wheels might be good for is on slippery surfaces such as ice. Or maybe during a flood where the corners of the square wheels could lunge the vehicle forwards in water. They definitely should be good on ice, though I'm not entirely sure because they could also continuously slip.*

[@lucidx2]

The Square wheels failed on the hill climb because the truck had way less momentum going up

I Reckon with the square wheels use wider trackshen to climb up the hill but the again I suppose that would be the round wheel

[@basildaoust2821]

Hey, if you always went straight on ice roads everyone who lives in Manitoba would be really happy, because what tends to happen is you do not always go straight and when the car decides it's going to spin you do not have any control if you a normal driver maybe some trained drivers would have no issue, I can't really comment on that.
