Heavy Machinery Tire deems your ramp unworthy.
DontcallmeLen
So I should put heavy machinery tyres on my mini.
Hybris51129
Yes! Just a little bit of axle and suspension work and regear the rear end a bit deeper and you'll be fine.
BoozeHound001
Oh sure, when they do it, it's "science". When I do it, it's "theft" and "destruction of property".
YourAlcoholicFriend
Rico did you fortify the ramp?

Plot twist : the heavy machinery tire did not stop there, and killed 31 innocent japanese people before its anger was appeased.
slaitch
While this seems like the sort of thing that would be on Japanese TV, it also looks like a completely stupid amount of fun.
ThatRussian
But the "supercar tire", new, assuming it's the rear tire, is >$1000. I don't even know how expensive the F1 tire would be...

The Judges would have also accepted "The Juggernaught of tires."
stilloldbull
The last run reminds me of an incident that occurred at a motocross race. We rolled a tire into the pits from the top of the hill climb...
stilloldbull
Wrought complete and utter havoc...
Rutroraggy
Once a something gets spin stabilized it tends to keep going in a straight line.
ChaosChosen
Its like if the tire is heavier, it goes faster down the ramp or something.
lygerzero0zero
Not true. Acceleration of gravity is constant, whereas these tires would be more affected by moment of inertia.
Speldrawng
It's the force that increases with a more massive tire. F=mA. Bigger m, same A = more F. TL;DR bigger tire = rekt ramp.
hawger
Tall, skinny and heavy.
IWasInsufferableIn2017
No. Some energy gets lost by friction and air resistance, but some also gets converted into angular momentum instead of velocity. (1/2)
eksoskel
That's actually pretty inaccurate by itself. I'd go into the details of what's actually going on, but it would take several comments.
Imaybegotthis
I'll just sum it up by saying Newton's Bears.
Corona688
Acceleration due to gravity is a constant. Rotational inertia and friction make the difference here.
NickRivieraMD
*Your high school physics teacher removes glasses, sighs and pinches nose as the vibrations from this statement echo through the unverse*
millertime89
There's a tradeoff too. You want less surface area to decrease air resistance. But with enough weight you can offset it.
myspacebarisnotworking
Get a flywheel. MAX SPEED ACHIEVED
gester737
yeah...science, bitch.
vengfish
Whie Sectional density and air friction plays a role, rolling resistance also plays a role.
FancyFrance
The have various coefficients of friction (see F1 tire, it's "sticky")
Horseclick
yes, and like the more grip you have, the slower the tire goes
spacedmonkee
Irrelevant test is irrelevant.
ohnoanotherputz
How dare you suggest that the timeless sport of tire jumping is irrelevant.
flickerdart
It's relevant to my interests (shit going fast, shit breaking other shit, sweet jumps).
PeskyGentlemen
It's entertaining
MostlyCatFavorites
Now I know not to drive with heavy machine tires while I do a jump off a wooden ramp
embiggenator
I'm sure the Mythbusters could come up with a legitimate (sounding) explanation
ByThePowerOfSCIENCE
And an additional test involving explosives.
geiokami
It actually shows how well certain tires stay on track, the economy one pulled to the right quite a lot. Also it shows how fast each one go
thisthingsibelieve
Yeah but look at the shitty unevenness of the ramp - the economy tire could have just been unlucky. Plus it's the skinniest of them all
GunCamel
A good demonstration of rotating mass and momentum .
dontevenworryrealfakedoors
Not at all, the f1 tire goes slower and does not go as far. It shows the superior grip of a tire needed to handle the g's of a formula 1 car
theconstermonster
I think the rigidity of the tires without inflation might have a lot to do with this as well
chansuke
Its also much lighter than the other tires.
agreyworld
But compare supercar with economy...
InfiniteSynapse
Exactly what I was thinking. The tire needs to stick to the ground and it did well.
fatyofdoom
Intro physics problem. They have different initial potential energies, heavy ones go faster...
fatyofdoom
Well okay it cancels but they all have different moments of inertia leading to different rotational energy. Not a good test.
warick
Yup. A much better scientific test would be to get tires of same diameter, then vary the tread for some tests and the material for others.
fatyofdoom
Or just put them on cars and test them way since rolling down ramps isn't the typical use of a tire.
msheiz
That would only be relevant if the ramp was slippery and the tires couldn't spin.
asa1967
Incorrect. Mu is mu. No matter the surface coefficient of friction, different tire C.O.F. will react accordingly
itsamazing
I have no idea what you just said, but it sounded all awesome and sciency
quantumpacket
Physicist to help! Mu(µ)= coefficient of friction. Very simply put, multiply weight by mu to get force of friction you gotta overcome.
asa1967
A high C.o.F (typically denoted by the greek letter Mu) means more grip. Ice on Steel has a low C.o.F, Rubber on Asphalt is on the upper end
chloramphenicolderivative
CoF is dependant on type of surfaces and slipperiness, so it might beat the other tires in this test, but lose on a slippery surface.
asa1967
Very true, but that's not what that dude(tte) was saying
KenKorte
Psh, we'll see what you say when my camaro is pulling sick jumps with truck tires
MoxieFox
Lost my self at the last one omg that ramp got wrecked. Lol

Glad I watched before I read this, cuz I had the same reaction. That was glorious.

i didn't see them write anything down...
Housemaster
Don't you see the recorded speeds and distances?
bigeduck
Obviously they did, some sort of "scientific" number showed up in the screen.
cleverbeans
They did however collect video evidence, which is basically a high tech method of writing stuff down.

The only difference between screwing off and science is writing things down

"Well, hello Joe and welcom to tire-science corp. We'd like you to carry those big ass tires up to the top of the ramp, nothing more!"

If I at least got to watch them get pushed down the ramp, I could do that all day long.
Icannevercomeupwithagoodorwittyusernamepleasehelp
Go to your nearest ski jump in the summer with tires and do this.
TheTreeGod
Hmm, sadly there hasn't been that much snow where I live so there aren't any open ski jumps.
Icannevercomeupwithagoodorwittyusernamepleasehelp
Where are you from?
TheTreeGod
I actually live in Alaska.... Its been a horrible year for snow.
YouCannotUnSeeThis
Well then, you wouldn't mind calculating the angular momentum of the last tire as well as the force at which it impacted the ramp with.(1/2)
YouCannotUnSeeThis
And then compute the stress that the ramp endured in this wreckage, would you?
YouCannotUnSeeThis
Ill give you some numbers to start you off. a=-9.8m/s^2, Vi=141 km/h, and the slope seems to be at a 55 degree angle. Good luck!
TheTreeGod
What is the radius and mass of the tire?
YouCannotUnSeeThis
Hard to tell. But lets just say 50cm radius and mass is 40 kg.
