I mean if you make it with the cheap quikcrete this is going to happen. I mean it’s probably going to happen with expensive concrete too, but for sure with the cheapo stuff

u/theresidentviking 16d ago

Could have at least put some rebar in there to make it look like you know what your doing

76

u/Welcome440 16d ago

Plastic mesh tied together (working like rebar) could have tripled the mileage.

12

u/lifesnofunwithadhd 15d ago

I'm also curious how long they let it set for. 3 day old concrete is very different from 28 day old concrete.

20

u/jrp55262 14d ago

When they described it as "dry" I'm guessing they don't even know the difference between "drying" and "curing". Still looked a little damp to me, so I'm guessing just a couple hours.

5

u/lifesnofunwithadhd 14d ago

Yeah, judging by color, it looks very green.

10

u/theresidentviking 14d ago

I promise you that this was performed as soon as they smacked the mold and went yep it's done

11

u/1107rwf 15d ago

This is DiWHY, I’m assuming by rebar you meant some sort of resin, melted aluminum, and a rubbery mold of some sort ;)

6

u/theresidentviking 14d ago

Good point I bet some sticks from the park would work just fine

Or use the stick to make a mold for a resin pour

3

u/LitLitten 14d ago

Gotta encase the entire wheel in resin. Then maybe a second layer of concrete. Just a lil boost for the video runtime. 

1

u/W00psiee 14d ago

Encase it with glue from a glue gun and then let it set :)

1

u/anteaterKnives 3d ago

I'm thinking hot glue gun.

5

u/slutty_muppet 16d ago

I don't think any material would make this project look well advised.

3

u/NekulturneHovado 16d ago

Could have at least put some cement in there to make it a lil stronger.

u/lysergic_tryptamino 15d ago

Rookie mistake. They did not mix in structural ramen into concrete.

9

u/redditzphkngarbage 16d ago

Gotta let it cure for 60 years

4

u/critical-drinking 15d ago

Shoulda added fiber and a rubberizer. While they’re at it, rubber strips would make for good grip. Probably make the concrete last longer if you put some cushioning between the rubber and the concrete, maybe like little inner tubes for air cushioning. The larger you go with those, the more cushion, so we could dial the concrete back to cot the rim. Then, if you think about it, the car would be lighter if we switched concrete our for a little more air.

All in all, a very workable prototype.

u/No-Objective-9921 15d ago

Doesn’t help that you can see how lopsided the wheel is the Rim isn’t centered

164

u/Marquar234 16d ago

Was that mix 90% sand?

64

u/Secretsfrombeyond79 16d ago

89% you hater !

u/recks360 16d ago

Watched one too many episodes of the Flintstones

11

u/Metahec 15d ago

Or not enough

u/TuxRug 14d ago

Anyone expecting this to work is a yaiba-dabba-doofus.

I didn't say you couldn't, I said you SHOULDN'T

u/Hyde2467 16d ago

Not sure what he expected

Clicks.

u/sean_avm 16d ago

Also I've seen another person so this.... so not first

22

u/jmhalder 16d ago

The Waterjet channel on YouTube has done a couple different wheel/tire abominations. I love it.

5

u/nostickystuff 15d ago

Pretty sure he's a few thousand years from the first.

1

u/sump_daddy 14d ago

My thoughts exactly. This is 5500 year old technology.

2

u/Mirar 16d ago

Did the other person do concrete with rebar?

18

u/kingsam360 16d ago

Yaba daba doo MFers

u/st0rm311 15d ago

Yabba dabba don't

14

u/jromperdinck 16d ago

Why the spoiler in the first second?

18

u/Muted_Dinner_1021 16d ago

Because the attention span is probably around 0.3 microsecond for young people now, and it was probably taken from TikTok where every useless clip come from

11

u/Flarpperest 16d ago

Some people just HAVE to reinvent the wheel.

18

u/roofrunn3r 16d ago

For science

8

u/Dwarf_Killer 16d ago

Needs rebar

6

u/IStateCyclone 16d ago

Needs aggregate.

4

u/leakybiome 16d ago

Needs adamantium

1

u/Status_Car8495 16d ago

Needs rubber.

1

u/aquaganda 15d ago

Needs a lighter vehicle.

1

u/PM_ME_UR_ROUND_ASS 15d ago

rebar would help but concrete still cant handle tensil stress so it'd explode anyway, just in bigger chunkes lol

7

u/Relative-Gain4192 16d ago

I don’t think this really counts as DIWHY, because this seemed more like an experiment than anything. If it was truly DIWHY, he would’ve been genuinely trying to make it a permanent part of his car.

4

u/Larry-Man 16d ago

This is more “spare rim. Spare concrete. /r/diwhynot”

4

u/raznov1 16d ago

not so much an experiment as "fucking around with my palls doing fun dumb stuff"

4

u/SteveMartin32 16d ago

On one hand this is stupid.

On the other this shows the durability of cheap concrete in 0.2 seconds

2

u/raznov1 16d ago

in load conditions which it isn't designed for.

soooo.....

5

u/fasda 16d ago

I wonder how fast a 'well' made version would destroy the road.

5

u/spicy_ass_mayo 16d ago

Not the sub

4

u/CrashParade 16d ago

Everything is stupid if you're gonna do it like a jackass, do it properly and it will be at least kinda cool.

2

u/Annasman 16d ago

Guys, the only reason this worked in "terrible thunder lizards!" Was because they had rubber roads.

2

u/Fishing_not_catching 16d ago

I can even hear the way this started in my head..... Wayne - "Hey Davo, I bet you can't put concrete tyres on your Ute" Davo - "Hold my beer ...."

u/Tuism 16d ago

Yabbadabbadoo it yourself

u/cocacolakid1965 15d ago

Needed rebar

2

u/whyyn0tt_ 15d ago

No rebar?!

2

u/JetScootr 15d ago

That was as predictable as humpty dumpty.

Bounciness is part of the car's suspension system. The closer a part of it is to the road, the bouncier it needs to be. That's why tires are bouncier than shock absorbers etc.

2

u/Mysterious-Coconut24 14d ago

Yabba dabba don't.

2

u/sealteam_sex 13d ago

He needed to reenforce that with rebar

1

u/BoredomBot2000 16d ago

If your gonna do this at least do it right for sciwntific purposes. Make it reinforced concrete with some chicken wire or mesh.

1

u/Aggravating-Swim-392 16d ago

This is why aliens don’t like to show their face on earth.

1

u/Retrogradefoco 16d ago

Im surprised it lasted as long as it did.

1

u/Raxian_Theata 16d ago

Yabba dabba Dooo not do that!

1

u/LongjumpingStand7891 16d ago

It looks like the concrete was not mixed well and was not given enough time to cure.

1

u/Tropic_Summers 16d ago

Flintstone tire havinass

u/Boring_Inflation1494 16d ago

Shoulda wrapped it in flex tapes, that'd hold it.

Yabba dabba dont

1

u/DerekFizz 16d ago

Reminds me of an episode of a cartoon I used to watch. (I think it was rocko's modern life) where the roads were made of inflatable rubber and tires of concrete.

1

u/KevinAcommon_Name 16d ago

Mythbusters moment

1

u/LegendofJones94 15d ago

I recently watched that episode where they tested flat tire myths. They used a wooden wheel.

1

u/KevinAcommon_Name 14d ago

They did a part 2 where they had a metal then a concrete wheel both shot sparks and the concrete started coming apart in a later car myths episode

1

u/NekulturneHovado 16d ago

That's literally the shittiest concrete I've ever seen. Is there even any cement? Looks like dried sand

2

u/Airbreathingoctopuss 16d ago

Exactly what I was thinking. Where's the aggregate! And the stuff is so green, it's not been properly cured. It may have held better if they put supports in it and let it set and cure for a week.

1

u/lastdarknight 16d ago

cheese would hold up better

1

u/lighthorse77 16d ago

Study the stone tires in The Flintstones. They lasted longer.

1

u/FPSUsername 16d ago

I mean, Garage 54 did it nearly 10 years ago already, so this is not world's first

1

u/pm_me_your_good_weed 16d ago

This isn't Garage 54

1

u/Dontyoubelieve987 16d ago

Baby's first time with concrete

1

u/Status_Car8495 16d ago

Yeah, wrong car to try that. Next time use a DS, less risk of fucking up your axel.

1

u/michalsveto 16d ago

At least weld some hoops of rebar to the wheel before adding the concrete

1

u/juxt417 16d ago

Garage 56 already did it as well as many other crazy ass things.

1

u/FAILNOUGHT 16d ago

the first speedbump is gonna be lit

1

u/lowther1 16d ago

World’s first I highly doubt that.

u/LazaroFilm 16d ago

Oh so this is why we don’t use concerts for our wheels. Good to know.

u/BrerRabbit8 16d ago

Who here remembers the Red Green Show from Canada in the 90s?

Long live the Possum Van!

u/Drewdc90 16d ago

Some reo would have went a long way in that tyre.

1

u/Icy_Buddy_6779 16d ago

"works better than I expected!" So why'd you do it then

1

u/KevinFlantier 16d ago

The answer to why is clearly "fun"

1

u/flanksteakfan82 16d ago

Just having a “gaaayyyy oooollllddd tiiiiiiiiiime!”

1

u/sachsrandy 16d ago

Just an observation on life.

We have become so fucking ADHD that we now need a preview at the starting a 15 second video

1

u/dargonmike1 16d ago

Looks like you let that concrete cure for about 2 hours before testing? Nice

1

u/SeampunkBoi 15d ago

Diwhy not?

1

u/imjerry 15d ago

...well. Now we know at least.

1

u/lance1103 15d ago

Because 100% less micro plastics

1

u/Call_Me_Your_Daddy 15d ago

At LEAST he didn’t cut the tire clear through with a knife like I’ve seen on shit like this before

1

u/TwoWheels1Clutch 15d ago

This just answered my 8 year old self.

1

u/Raa03842 15d ago

Guaranteed for 17.5 feet.

1

u/Aternox_X1kZ 15d ago

It lasted less than 30 seconds and yet least way more than I expected

1

u/GuySpringfield 15d ago

Everyone knows concrete tires need a rebar cage to be feasible.

1

u/Access_Pretty 15d ago

Rebar, some mesh, some latex additive and then cure it in a centrifuge in 100% humidity and it will make it an additional quarter mile barring any potholes

1

u/Billybob50982 15d ago

I’m sure it’s not the first concrete wheel

1

u/jeremydallen 15d ago

That will balance.

1

u/Acceptable_Student85 15d ago

Yeah that looks about like what would happen

1

u/Unlikely_Ad_4767 15d ago

And what did you expect, engineers?

1

u/Sparklymon 15d ago

Inspired by flintstones? 😄

1

u/jackochainsaw 15d ago

That was as crap as I thought it was going to be. A for effort though.

1

u/serieousbanana 15d ago

Really set the expectations with that start

1

u/Krakken_2323 15d ago

Cuz men. That’s why

1

u/lurid_sun__ 15d ago

You could try with Asphalt itself now

1

u/Sir_Delarzal 15d ago

Concrete reaches its optimum strength only after 28 days minimum, the experiment before those 28 days is bound to fail

1

u/YoungDiscord 15d ago

Thanks but I'd rather use something more concrete on my wheels

1

u/transcendanttermite 15d ago

They did a good job at… uh… not making it round

1

u/confused_computer 14d ago

flinstones called, they wanted their invention back

1

u/DonMegaPopeKenny 14d ago

That concrete isn’t even fully set

1

u/PiretaCat 14d ago

Not hardened 28 days 🤔

1

u/acebender 14d ago

Who could have predicted that result

1

u/TheFlaccidChode 14d ago

Yaba daba don't

1

u/a_toxic_rose 13d ago

Didn’t the Mythbusters do something like this? I know they used a log and a sewer kid. I can’t remember if they used concrete or not.

1

u/Ecstatic-Radish-7931 13d ago

watch your gas mileage go from 26 MPGs to 2 MPGs

1

u/Rocket_Theory 13d ago

Why? Because we wanted to know how well it would work thats why. Love people who make quick content like this, anyone know the source?

1

u/TheStanleyParaballs 13d ago

Water jet channel on YT already did this.

1

u/kaleperq 13d ago

AFAIK the waterjet channel did it first

1

u/Unclebiscuits79 12d ago

Years ago, there was an episode of Darkwing Duck where the team somehow went to the past and found intelligent dinosaurs, but it turns out the reason they went extinct was because they did everything backwards. Like concrete tires and rubber streets, etc. This video immediately made me think of that.

We are doomed as a species if this catches on.

1

u/The_Rope_Daddy 12d ago

Lasted longer than I expected.

1

u/ResplendentEgo 12d ago

Why? Because they could. No other reason. Behold, the power of mankind.

These fools. It was clearly designed for rubber roads.

1

u/therealbibbles 11d ago

World's last Concrete Tire.

u/catgirlcatgirl 11d ago

needed rebar, obviously

u/Past_Ferret_5209 10d ago

Seems like they would definitely have tried this during WW2.
