I hate how they got the myth wrong I have never heard of a beheading from the tread but I have heard allot about split rims coming apart and cutting limbs and such off
@xPATCHESOHULAHANx the retainer on the rim itself really is the most deadly thing about them!, seen and herd of many serious accidents and even deaths because of them not being locked in properly before the tire is inflated.
When I was 16 I was walking from where I lived to the next village and big rig came past and its whell fell off, it came hossing towards me, my mate saw it {luckily} and jumped over a fence then shouted and started laughing {i didnt hear him} Iturned to see what he was pointing at and as i turned it shopt past my face missing me by an inch or so.I still didnt see it until I turned back to face the wayt I was walking and saw it in front of me running along the path and it went rthrough the fence
The result here is seriously flawed. The myth was if a piece of rubber that was run over could kill. The "rubber chucker" uses the same principals as a baseball pitching machine, which is an object passes through two spinning wheels, whereas in the real world if a piece of rubber is run over on the freeway, there is only one spinning wheel on the top side and the ground is stationary. Also, it was elevated instead of on the ground and the windshield of a car uses a much denser piece of glass.
Gimmedaloot754 is wrong he doesn't realize a wheel turns while on a truck and could fire in the opposite way the truck is traveling depending on how the tire busts and what position the tire is in when a chunk from a certain spot on the tire gives way
Did anyone notice that the balistics gel dummy faces the wrong direction relative to the car door. It makes no difference in this scenario but imagine driving like that
there are so many aspects wrong with this experiment its scary that people will watch this and believe the pile of horse manure...lol. First off, the total momentum going away from the truck is 40 mph, which is not real world. Have to take into account that the wheel is traveling in the same direction as the truck at 40 mph and pretty much so is the traffic, which will effectively cancel out this alleged total momentum with they pretty much all in the same reference frame...lol. Fun tho!
I don't see how in a real situation a piece of rubber can fly trough the side window at 40mph. The front window would be possible, but I think the angle and double glass with plastic foil in the middle will keep the passengers unharmed. Motorcyclists are less fortunate though...
@Clarckson1 correct,but the side windows and rear window/windsheild are shatter iminent tempered glass without the special plastic in the middle. Therefor would just shatter into a billion pieces. Also unlikly to cause death by the tiny glass shards. Isnt technology great?
@BonezofNY What most people don't know, is that there is a strong plastic foil in the middle of the windshield, so basically it exists of 2 windshields, and the plastic foil in the middle, which prevents the glass from shattering when broken
Awesome!!! That ballistics gel dummy just got his shit rocked!!
man great show, wish my job was blowin shit up, and throwin shit at other shit to see if it'll break . . . man to be paid for that would be the ultimate
I don't know if this has been mentioned before or not, BUT it's 80mph the tire was doing. If you stop 1 wheel from turning the diff will cause the other wheel to spin at double the speed, it's all to do with how the spider gears in the diff work.
@69aussieguy Dude it's 40 only....(it's called pure rotation - The tip of the tire in touch with the ground is always at rest, unless skidding. So if you vehicle moves at 40 the tip of the tire is moving at 40 backwards so that it is at rest wrt ground)
I love the show and have learned lots from it. However this myth was NOT "put to the test" properly. The piece of blown tires acceleration is 0. It is "fed" in between the two rapidly spinning tires which results in it being "fired". That is very different from a tire which is laying on the asphalt with the truck approaching and running over it. The energy released from the trucks' tire running over the blown rubber at 40mph, would be a tiny fraction of the energy from the two spinning wheels.
@fivemanfloyd From what I saw, the myth was if the tire exploded, not if a truck ran over the debris. The rig they made was simply to propel it at a similar speed as they observed at their original experiment.
@fivemanfloyd Its about rubber FROM the wheal when the weal explodes, i dont doubt this cuz ive been behind a truck going 90km/h when this happened, i got 1 headlight, 1 dim light and the front bumper destroyed

They needed confirmation if a flying piece of tire at 40mph hitting at the right angle would kill someone in a car? a small stone would do that! How this can be a myth?
This guys have the best job in the world. I wish i had some money to at least buy me some tires for my truck, and look at this morons destroying stuff and getting paid to do it
No, no, no, no, no. This test is completely pointless;
1# The test was a truck tyre blowout at 40mph. Which they tested at stationary. If a truck tyre blows out travelling at 40mph it does not travel in reverse. It is still moving forwards at 40mph. Therefore not injuring anyone standing behind the vehicle at all.
I'm surely not the only person who must point this out?!
@razers1 the car driving behind negates that. that's why even stationary it makes no difference.
tire flies at 40mph off the truck in reverse as in from teh bottom of the tire flying back, but truck is going at 40mph anyway so it's negated, except that the car behind is moving at around the same speed, 40mph, so it's more like the car hits the tire rather than the other way around, same results.
Friction slows down the tire instantly when it bursts. On my interstate a blown big rig tire tore my ranger's lower valence off with no effort and cracked my grille. No doubt I don't think this could smash my windshield.
There is a problem here though, the window the tire went through was a side window, not a windshield...
The Difference? Windshields are made from a safty glass and don't shatter quite the same way as side windows do, also, most windshields are at more of an angle.
The combination of these traits would definitely give the driver a better chance.
So you're saying that when your speedo says 100mph on snow your tire is actually spinning 200mph? I don't think i have ever had a tire spinning 200mph on my 4cylinder Chevy S10.
No, that's not what CoolVlguy said. He said that if one side is held still, the other side will be spinning at twice the speed of what the speedometer says.
It's just what differentials do because of the gearing system in them.
Another thing to consider...if the opposite drive wheel on the truck was not freewheeling then the actual speed of the tire is double what the speedo indicates...this is how spider gears in the diff work..like when you do a one wheel peel burnout the speed is double what yer speedo says
@CoolVIguy would you mind explaining the science behind your theory here? As I understand it, the speedometer readings are not meant to show wheel speed, but mathematically computed vehicle speed as it is extrapolated from a sensor (gear) in the transmission or transfer case while the vehicle is in forward motion.
No, he is correct. In a standard differential if one tire is stationary and one is spinning the spinning tire will be going 2X the speed the speedometer says.
It doesn't seem to matter here though because it appears the opposite tire is probably off the ground and spinning.
@Oddwun - Again, I ask for a scientific explanation, not a restating of the original statement. I want mathematical formulae here based on the proven and hypothetical math involved.
I don't know what sort of formula I can use to show how a set of gears works. It's mechanical, when you mesh gears in certain fashions they operate with certain results. A differential uses ring and pinion and sun and planetary gears. I cannot draw you a technical diagram here, nor can I explain how the system works in 500 letters, go look it up yourself. You will find that is exactly how it works...if one wheel is stationary the other wheel will be spinning twice what the speedo indicates.
@Oddwun - Dude - I was doubting the claim, but open to reason and logic. I finally did look it up in an old Peterson 4x4 book. and it stated it quite plainly. Basically "The average speed of the two tires speeds will equal the vehicle's indicated speed." So an open differential basically has infinite differentialling ratio, But it does follow the simple formula : left wheelspeed + right wheelspeed divided by number of wheels (2) = vehiclespeed. Or (A+B)/2=C. 0mph + 200mph / 2 = 100mph.
Assuming it's a standard differential, you are wrong. If you put one tire on the ground and jack one tire up and then drive the vehicle the tire up in the air will spin and the tire on the ground will not, the car will not move. That's the way it works.
@CoolVIguy - I ask you - at which point of the tire do you read MPH? How do you relate engine RPM to transmission output shaft RPM (at which place the speedometer sending unit gets its data to indicate vehicle MPH)? How do you relate output shaft RPM to wheel RPM and thereby compute vehicle speed? In other words. If the spinning wheel is on ice and the non-spinning wheel is on dry pavement, and the vehicle is immobile...the vehicle speed is 0MPH!, it doesn't matter what the speedo says!
@CoolVIguy MPH as read by the speedo is a vehicle-related measurement, not a tire-related measurement. If you take the circumference of the tire, and multiply that by its RPM, then you can extrapolate tire speed from that, but it is not related to the speedometer because an open differential does not have a fixed ratio of differentiating, so wheel rpm from one side to the other of the axle is not a given ratio. One tire could be stationary and the other spin anywhere from 0 RPM to 10,000 RPM+.
its ballistics gel, is the most common human anologue because it has the same density and water content as human flesh, im not suer how to make it, but thats why youtube is here
Regardless of whether the tire flies up or not, a truck tread is something to be sure to avoid. May not be something to worry about hitting you in the face, but I've witnessed first hand a full size F150 truck totaled by hitting one of those tires.
Ok so I take it no one here watches Smoking Gun? Because something like this was caught on camera, the tire of a big rig CAME OFF, it didn't explode I'll give you that but IT CAME OFF, it BOUNCED ACROSS SEVERAL LANES OF TRAFFIC, it then SLAMMED into the side door/window of a car, and with tremendous force as it was launched skyward after the hit.
Heaven forbid if it had been a guy on a bike.
So while I still take this with a grain of salt, concerning big rigs you can never be to careful :/
more noob busters. The tires on the big rig are rotating and moving forwards so the rubber when it is thrown off by a blowout will not be thrown out the back as is shown here.
exactly. The tire is rotating and the vehicle is in motion. If the tread comes out the back it loses the vehicle speed. If it comes out the front it is fighting wind resistance. This test is faulty as it does not include any elements related to motion of the vehicle or resistances.
for sure. I'm not saying they're not capable of doing damage but the setup for the test was incredibly flawed. I've been around 18 wheelers (and larger) for my entire life and never seen anything remotely close to this kind of stuff happen.. though i've seen some stuff for sure.
mythbusters in the actual episode stated that this type of blowout is very unlikely, the scenario their testing is a "what if it does" test. and the rig was designed to launch the piece at the speed they got from the previous tests with the piece not from going at the speed the truck was going at you notice they only ran the rig up to 35, highway speed is around 80 no?
@Panzervagon lets not forget that due to the way the tire blows out the piece of rubber should be going near 0 ground speed. but you driving the car slightly behind the truck would be going at whatever speed you are. so you hitting the rubber at 35 mph is the same as if you were sitting still and it hitting you at 35mph
But the piece of tire still has a relative speed to anything moving along with the truck
Truck at 40 MPH, you drive behind it with 40 MPH, the piece of tire comes out of the back of the truck with a relative speed of 40 MPH to the truck and you. It might actually seem to stand still to anybody on the side of the road, so it'll look as if you drove into the piece of tire, but in the end it still hits you with 40 MPH!
So whether truck and target move or not, does not really come into it!
It does not matter where you are or what direction your going, you do not want to be near a semi tire when it blows. Murphey's Law clearly states, "If something can go wrong, IT WILL". Don't be caught unexpectedly, try not to drive next to a semi truck for any length of time.
Wrong, it would be ZERO. if a stationary setup shoots 40 MPH backwords, than a setup, that moves forword at 40MPH, would just leave it's debries on the side of the road, with no backwords speed.
The myth here (as I understand it) is what happens to someone driving behind such a track. so to such a driver, the track is stationary, and so the drbries are shooting towords him at 40 MPH.
This is actually wrong. When the rig losing the piece would travel at the same speed in the same direction, the two 40mph values equal each other out, the impact doesn't double.
Umm they put it through side window of a car.. they're nothing like the windshield.. and for that to happen you would actually have to drive sideways behind a big rig at the exact moment the tire blew, it would have the be a torn off tread AND you could be no more than a About 20 feet away when the tire came at you... Seems tough to pull off.
This comment has received too many negative votesshow
well, if you're driving behind a big rig and you see/hear the tire blow you would slam on the breaks and swerve the car causing it to turn sideways, therefore allowing the tire to fly through the window taking your head off.
No, you could be passing the semi when the tire blows, and that's pretty much what they show here. I don't see how being behind the semi when it blows and goes through the windshield would be any better, really.
oh man i remember this, they did this on CSI and adam and jamie were guest stars of it as the balistics test engineers for that episode where the guy in a gokart got his head ripped off by a tire
The only limitation to their experiment is the number of trials and situations. With an estimated 650 millions cars on the road in the world right now, odds are that cars and people get hit with chunks of disintegrating tire on a regular basis. Every now and then I drive past large chunks (10 to 20 lbs) of tire sitting on the edge of the road.
I once read many years ago where a camaro was behind a semi when the semi blew out a tire. A part of the tire sliced through the windshield and decapitated them. It's the steel belts in these tires that allows them to slice right through a window. This is a real story by the way.
This happend to my old man driving home 12pm at nite. it went straight threw the windscreen and hit the passenger seat. huge amount of damage! seat was stuffed and the roof was buckled. the peice of rubber was about 1m long!
What I don't get with this myth is that when looking at the replay of the original test. None of the pieces that flew off went in a straight line like the final test. They all either flew up in the air or hit the truck or the pavement. I think it would be next to impossible for a piece of a tire that big to leave a tire and fly like that into a car's interior.
well because of the tires explosion, the rubber peices would be, well yea, crazy. they are just trying to see whether it could do it, not if it would do it.
Pause at 1:32. Not trying to be sick, but look at the back tires, the arrow, the piece of ruber, and the human drawling. Theres something dirty looking.
They were trying to see if there was enough force to penetrate the window. They used a car door window probably out of convenience (i'm guessing they had it in the back of the shop). That doesn't mean that in the myth somebody drove sideways behind a semi when the tire exploded and/or that it wouldn't penetrate a windshield. Besides if it can kill you from the side it can kill you from any other angle. A broken neck is a broken neck!
..and the driver's head would be the "projectile". Granted both would still collide at roughly 40mph, the manner in which they make contact would be far from similar to that shown in the simulation where the entire length of the tire tread strikes the "target" right at the same spot, concenrating its energy. Had the tread hit the car door on a more lateral angle, most of its energy would've dissipated on the door and glass and would've unlikely ripped the head off.
ROFLMAO. Half of the nerds are freaking out over how this could not happen and the other half are haveing orgasims over what they just watched. Its a show num nuts its not saying this will ever happen its saying that it can. So stop trying to show off pussys XD.
there's a flaw in your logic, buddy- the tire spins... it doesnt just scoot forward- thus giving the momentum to launch a chunk backward. simple physics. trying to explain that this is impossible is like trying to explain gravity doesnt exist.
and another point is considering the glass your going to get hit by , the rubber tire , its force and the probability that you are going to lose control of your car not to mention your consciousness . Even if u survive the hit your still going to die really painfully at least if you break your neck u wont feel anything :D
I disagree on this being an accurate enough simulation. First off, the energy of the tire's rotation would have little if anything to do with the impact created by the projectile upon the target. Reason being is that the tire would actually be moving forward at 40mph (unless the truck itself was stationary and was merely doing a burnout at an equivalent roadspeed of 40mph). Therefore, rather than being the projectile, the ejected piece would then become the target...

A differential uses ring and pinion and sun and planetary gears. I cannot draw you a technical diagram here, nor can I explain how the system works in 500 letters, go look it up yourself. You will find that is exactly how it works...if one wheel is stationary the other wheel will be spinning twice what the speedo indicates.

@Oddwun - Dude - I was doubting the claim, but open to reason and logic. I finally did look it up in an old Peterson 4x4 book. and it stated it quite plainly. Basically "The average speed of the two tires speeds will equal the vehicle's indicated speed." So an open differential basically has infinite differentialling ratio, But it does follow the simple formula : left wheelspeed + right wheelspeed divided by number of wheels (2) = vehiclespeed. Or (A+B)/2=C. 0mph + 200mph / 2 = 100mph.

When the oposite drive wheel wasnt freewheeling, the truck would have MOVED IDIOT!
What would they do, chop off the Tire? Even then the axis would be freewheeling...
Chrinik 2 years ago
Assuming it's a standard differential, you are wrong. If you put one tire on the ground and jack one tire up and then drive the vehicle the tire up in the air will spin and the tire on the ground will not, the car will not move. That's the way it works.
Oddwun 2 years ago
@CoolVIguy - I ask you - at which point of the tire do you read MPH? How do you relate engine RPM to transmission output shaft RPM (at which place the speedometer sending unit gets its data to indicate vehicle MPH)? How do you relate output shaft RPM to wheel RPM and thereby compute vehicle speed? In other words. If the spinning wheel is on ice and the non-spinning wheel is on dry pavement, and the vehicle is immobile...the vehicle speed is 0MPH!, it doesn't matter what the speedo says!
tinkerjeep 2 years ago
@CoolVIguy MPH as read by the speedo is a vehicle-related measurement, not a tire-related measurement. If you take the circumference of the tire, and multiply that by its RPM, then you can extrapolate tire speed from that, but it is not related to the speedometer because an open differential does not have a fixed ratio of differentiating, so wheel rpm from one side to the other of the axle is not a given ratio. One tire could be stationary and the other spin anywhere from 0 RPM to 10,000 RPM+.

Regardless of whether the tire flies up or not, a truck tread is something to be sure to avoid. May not be something to worry about hitting you in the face, but I've witnessed first hand a full size F150 truck totaled by hitting one of those tires.

Ok so I take it no one here watches Smoking Gun? Because something like this was caught on camera, the tire of a big rig CAME OFF, it didn't explode I'll give you that but IT CAME OFF, it BOUNCED ACROSS SEVERAL LANES OF TRAFFIC, it then SLAMMED into the side door/window of a car, and with tremendous force as it was launched skyward after the hit.
Heaven forbid if it had been a guy on a bike.
So while I still take this with a grain of salt, concerning big rigs you can never be to careful :/

If they blow out they can go in any direction
Dayberry 2 years ago
exactly. The tire is rotating and the vehicle is in motion. If the tread comes out the back it loses the vehicle speed. If it comes out the front it is fighting wind resistance. This test is faulty as it does not include any elements related to motion of the vehicle or resistances.

for sure. I'm not saying they're not capable of doing damage but the setup for the test was incredibly flawed. I've been around 18 wheelers (and larger) for my entire life and never seen anything remotely close to this kind of stuff happen.. though i've seen some stuff for sure.
NVMDSTEvil 2 years ago
mythbusters in the actual episode stated that this type of blowout is very unlikely, the scenario their testing is a "what if it does" test. and the rig was designed to launch the piece at the speed they got from the previous tests with the piece not from going at the speed the truck was going at you notice they only ran the rig up to 35, highway speed is around 80 no?

@BringerOfD It's the speed the piece of rubber left the tire, not how fast the truck was going, silly.
Panzervagon 7 months ago
@Panzervagon lets not forget that due to the way the tire blows out the piece of rubber should be going near 0 ground speed. but you driving the car slightly behind the truck would be going at whatever speed you are. so you hitting the rubber at 35 mph is the same as if you were sitting still and it hitting you at 35mph
BringerOfD 7 months ago
But the piece of tire still has a relative speed to anything moving along with the truck
Truck at 40 MPH, you drive behind it with 40 MPH, the piece of tire comes out of the back of the truck with a relative speed of 40 MPH to the truck and you. It might actually seem to stand still to anybody on the side of the road, so it'll look as if you drove into the piece of tire, but in the end it still hits you with 40 MPH!
So whether truck and target move or not, does not really come into it!

if you were driving at it at 40 and the tire was going at 40 in the opposate direction it would hit you at a force of 80mph

It does not matter where you are or what direction your going, you do not want to be near a semi tire when it blows. Murphey's Law clearly states, "If something can go wrong, IT WILL". Don't be caught unexpectedly, try not to drive next to a semi truck for any length of time.

Wrong, it would be ZERO. if a stationary setup shoots 40 MPH backwords, than a setup, that moves forword at 40MPH, would just leave it's debries on the side of the road, with no backwords speed.
The myth here (as I understand it) is what happens to someone driving behind such a track. so to such a driver, the track is stationary, and so the drbries are shooting towords him at 40 MPH.

well say the debries flew up in the air at eye level. if you hit it doing 40 mph. that would be the same thing as what they just did.

This is actually wrong. When the rig losing the piece would travel at the same speed in the same direction, the two 40mph values equal each other out, the impact doesn't double.

Umm they put it through side window of a car.. they're nothing like the windshield.. and for that to happen you would actually have to drive sideways behind a big rig at the exact moment the tire blew, it would have the be a torn off tread AND you could be no more than a About 20 feet away when the tire came at you... Seems tough to pull off.

well, if you're driving behind a big rig and you see/hear the tire blow you would slam on the breaks and swerve the car causing it to turn sideways, therefore allowing the tire to fly through the window taking your head off.

Your head would be off before you realize the tire had blown. And this would go right through a windshield as well as a regular window.

No, you could be passing the semi when the tire blows, and that's pretty much what they show here. I don't see how being behind the semi when it blows and goes through the windshield would be any better, really.

The only limitation to their experiment is the number of trials and situations. With an estimated 650 millions cars on the road in the world right now, odds are that cars and people get hit with chunks of disintegrating tire on a regular basis. Every now and then I drive past large chunks (10 to 20 lbs) of tire sitting on the edge of the road.

I once read many years ago where a camaro was behind a semi when the semi blew out a tire. A part of the tire sliced through the windshield and decapitated them. It's the steel belts in these tires that allows them to slice right through a window. This is a real story by the way.

What I don't get with this myth is that when looking at the replay of the original test. None of the pieces that flew off went in a straight line like the final test. They all either flew up in the air or hit the truck or the pavement. I think it would be next to impossible for a piece of a tire that big to leave a tire and fly like that into a car's interior.

Besides, who would be "drifting" their car sideways behind a tractor-trailer at 40 mph?
kiddopocktoole 3 years ago
They were trying to see if there was enough force to penetrate the window. They used a car door window probably out of convenience (i'm guessing they had it in the back of the shop). That doesn't mean that in the myth somebody drove sideways behind a semi when the tire exploded and/or that it wouldn't penetrate a windshield. Besides if it can kill you from the side it can kill you from any other angle. A broken neck is a broken neck!
didaludi 3 years ago 2
..and the driver's head would be the "projectile". Granted both would still collide at roughly 40mph, the manner in which they make contact would be far from similar to that shown in the simulation where the entire length of the tire tread strikes the "target" right at the same spot, concenrating its energy. Had the tread hit the car door on a more lateral angle, most of its energy would've dissipated on the door and glass and would've unlikely ripped the head off.

there's a flaw in your logic, buddy- the tire spins... it doesnt just scoot forward- thus giving the momentum to launch a chunk backward. simple physics. trying to explain that this is impossible is like trying to explain gravity doesnt exist.
opie353 3 years ago
and another point is considering the glass your going to get hit by , the rubber tire , its force and the probability that you are going to lose control of your car not to mention your consciousness . Even if u survive the hit your still going to die really painfully at least if you break your neck u wont feel anything :D
Intikas2 3 years ago
I disagree on this being an accurate enough simulation. First off, the energy of the tire's rotation would have little if anything to do with the impact created by the projectile upon the target. Reason being is that the tire would actually be moving forward at 40mph (unless the truck itself was stationary and was merely doing a burnout at an equivalent roadspeed of 40mph). Therefore, rather than being the projectile, the ejected piece would then become the target...
