- Plane tires need to support thousands of pounds of weight at high speeds, so why don't they pop? We talked to Goodyear, one of the leading manufacturers of plane tires, who told us why.

Why Plane Tires Don't Explode On Landing - Věda a technologie
This is like if a high school student researched aircraft tires for a couple minutes and presented it the next day
She even has the pauses to reach the time limit
The interesting is, there are 2.9m students already viewed her video next day😀😀😀
Old habits die hard
yeah lol
True🥧
You're making it seem as the plane lands vertically at 170+ mph. When in reality most of its speed is horizontal not vertical. Unless you're Ryanair
I think Ryanir lands at a speed rather like 270 mph v/s
Ryanair:200 knots vertical
Lufthansa:150 knots BUTTER
Are Ryanair landings really that bad? Just asking... Never travelled in one.
Ryanair stops its planes by sticking their feet out flintstones style
J D nope, they're fine
"They raise the tire only five centimeters off the ground, which doesn't feel like enough room to fit a thumb..." so as well as doing the barest attempt at research and physics not being their strong suit, clearly they have no idea what 5cm looks like either.
@@valentin.kompatscher If your thumb DOESN'T fit in a 5cm gap, you got issues.
Or what a thumb looks like

An american thumb might be fatter than average.

They are made in a way to withstand the pressure.

@@yagoovirus2751 everything, the reason the 737 became the Ford Pinto is because of domestoterrorat thinking.
Legions of girlymen with cute beards and clean fingernails who could design an alternator, but couldn't change one out if their libtard life depended on it.
Most engineers of yesteryear grew up with a wrench in their dirty little hands.
Quick answer: They are designed for it
Thanks for the likes !!
Less quick answer: They're inflated for high air pressure which makes it stronger and with nitrogen so high temperatures and pressure changes have less effect on them.
@jacob marr It's called watching a video and summarizing. Calm your nuts.
Ah thank you

Correction, dropping a tractor from 40,000 feet is by far the best way to plow a field
Correction: Planes don’t fall out of the sky, they simply glide down... and most commercial jet do not have 20 tires... narrow body’s have 6 or 10 (only 757), wide body’s have around 10 or 14 (777 and A350-1000) and double decker have around 18-22 tires.
I'm sure majority of that energy when landing goes to the *suspension*
yepp
Shock and tension struts correct
The “suspension” of an aircraft is literally just pressurized nitrogen.
That’s all. There’s no springs at all.
There’s a hydraulic shock, but it doesn’t support the aircraft.
@@Bartonovich52 you’re completely wrong. Planes have heaps of suspension depending on the LW (Landing weight)
@@Bartonovich52 Ya know what those nitro shocks are?
🥴✨ S U S P E N S I O N ✨🥴
I don't think Airplanes touch down to the ground straight down at 170MPH, they fly horizontally at around that speed. The touch down is around 50 feet per minute or as less as the pilot can do to make a smooth almost weightless touchdown once contacted on the ground the spoilers come up and push the aircraft more onto the ground and create drag to slow the aircraft down
Yeah, you’re right. Whoever produced this video was clearly under qualified
@@trojan-david *LmAo yOu dOnT kNow wHaT sPoileRs aNd fLaPs ArE?* Flaps are the things extending, to generate more lift, so the plane can fly slower. So it doesnt have to land at 220kts, but instead can land at 140kts, which is way safer, since the distance to stop is smaller. Spoilers do the exact opposite. They destroy the lift, so once the aircraft touched down it wont bounce up again, and since the lift is minimized the pressure on the tires is greater, and thus the traction between runway and tire is greater. And of course spoilers create additional drag, as well as flaps do.
TLDR: Flaps = More Lift at less speed + drag Spoilers = Destroys lift/ presses aircraft to ground + drag
Typical Vertical speed at touchdown is ~150 fpm. Too slow vertical speed may be counterproductive. Depending on weather and RWY Condition it might be safer to land at a higher verical speed. For example to prevent aquaplaning
Analool yh sorry I just did some research about it. You’re right
@@trojan-david Well that was unexpected. Most ppl on yt would be stubborn about it :D
They sometime do explode on landing. I work at an airport and saw a jet fighter's tire blow out. The system automatically blew out the other rear tire, to keep it straight on the runway.
Just imagine the pilot coming on the intercom and saying "ladies and gents, our tires have exploded on contact, prepare for some slip and sliding"

How to demonstrate something's toughness: compare it to a watermelon.
Also the watermelon needs to hit the ground at a -vertical- horizontal speed of 170mph

"The reason we have grooves in an aircraft tire at all is because we need to evacuate water if we were to land on a wet surface."
Me and F1 fan: So they're running inters!
Yeah also a bit simplistic. It's the reason *ANY* tyre has grooves in it. She sort of touched on the real reason for the different patterns but the explanation was confusing at best, and kinda reinforced the erroneous impression that a lot of people have that car tyres have treads for "grip".
Lando would try to land using slicks at the runway.
Or full wets
"Semitruck tires aren't supposed to explode, but they do."
All the more reason to reinforce semitruck tires.

I'm an A&P Mechanic/Flight Engineer and I can tell you that those numbers are WAY OFF
1. Only Jumbo Jets such as 747, A380, AN 225 , have tires in the double-digit range, not all commercial jets.
2. 500 Landings? No way in hell even on Autolanding. With the way these pilots land the plane, it will be a miracle to get 100 landings out of it.
3.The only way it takes an hour to change a tire is if you take a 30 minute break while changing it.
0:36 “tarmac” you can tell shes never heard a thing called a runway

In the aviation world it is sometimes called the tarmac, so she is correct.

Hats off to you sir.
Simple answer-It is a harder tire.There saved ya 5 minutes
And filed w/nitrogen
Also, a plane does not land vertically. The vertical velocity is nowhere near the speed quoted at the beginning, with the watermelon.
RIGHT? IT'S A STUPID VIDEO WHICH I STOPPED WATCHING ONCE THEY DROPPED A WATERMELON.
Christophe Boulet motion in the vertical direction is independent of the horizontal direction. Physics.
Thank u
1:56 from when did nitrogen become an inert gas? Add a matter of fact, the formula of gaseous Nitrogen is N2. N2 is very less reactive due to 3 Pπ-Pπ bonds which is highly stable. The only inert gases are He, Ne and Ar
Huh? What about other group 18 gases???
Also, I think they only meant that nitrogen gas is inert (as is non-reactive), not like it's literally in group 18
it doesnt have to be noble to be inert i dont think
Nitrogen is an inert gas tf
Inert is relative. Compared to oxygen or fluorine, most gasses are inert. Unless you are performing the very specific harber-bosch process, n2 is going to be pretty inert.
Nitrogen is less sensitive to temperature changes. That's why they use it.
Not just the tires but the asphalt on high traffic runways is unique that it "stretches" on impact. It is definitely multiple variables leading to success and sustainability.
The airplane doesn't land straight down! Now I can't trust anything else is true in the video
right, some big idiot made this video
Same with tarmac, tarmac is the stuff used to pave the runway, but there is no such thing as a tarmac on a runway/taxiway
Not to mention suspension plays a huge role.

You can't drop a watermelon at 170 mph, the melon's terminal velocity is only about 112 mph.
It depends on the height where you are dropping it
@@kamitsoglouuu umm,I don't think terminal velocity depends on height??
@@bigechungus6778 well, technically it does as air pressure and therefore air density drops with increasing height. This reduces drag at high altitude which raises the terminal velocity as it is governed by the equilibrium of gravitational pull Vs. Atmospheric drag. If you were to drop a watermelon from the stratosphere, I guess it would slow down quite significantly on its way down....
@@bigechungus6778 launches a watermelon in space to the surface of the moon accelerating gradually to 170 mph. Oh wait, space is a vacuum. Best to leave the comments

3:01 Commercial jets usually don't have 20 tires. Even the Boeing 747, one of the biggest commercial jets, have 4 main landing gears and a nose landing gear, have 18 tires only (4 on each MLG and 2 on NLG). Other smaller aircraft commonly seen like Boeing 737, 757, 767, 777, 787, Airbus 330, 340, 350 have around 10 to 14 tires.

Yep. 200 psi and the rims are two halves held together by a ton of bolts. If those bolts crack.. then the only thing holding it together is the axle nut and wheel bearings.
First thing I learned about airplanes was to always depressurize the tire before removing the axle nut.

Runways may be a man-made surface (often asphalt, concrete, or a mixture of both) or a natural surface (grass, dirt, gravel, ice, sand or salt). Runways, as well as taxiways and ramps, are sometimes referred to as “tarmac,” though very few runways are built using tarmac
Some runways ARE tarmac though, so theres that.

"If you dropped a watermelon..."
People, planes don't drop when they land! (it's called a crash, otherwise!) They transition from the wings providing lift (obviously supporting the fuselage as a result) to the tyres progressively taking the plane's weight as it decelerates.
"...at 170 MPH..."
Again, people: Any object falling at that speed and *abruptly* hitting the ground...is going to do a whole lot more than pop. A 500,000-pound plane would smash to pieces and leave a crater--'tyres popping' would be the least of your concerns!
1:06 #facepalm
@ZeHoSmusician
For the first bit, what else where they supposed to say?
“If you transition the watermelons wings providing lift to the watermelons tyres progressively taking the watermelons weight as it decelerates.”
Also, an average 747 would be landing about around 25,0000kgs. The landing speed would be around 145kts-150kts (166mph-172mph) depending on the landing flap setting selected.
ZeHoSmusician yea no shit srry we all know planes don’t just drop but it was a nice segway into the video why do you have to take things so literally?

Brandy: Nitrogen is an *inert* gas
It’s used to inflate aircraft tyres and occasionally with car tyres. The only car I can think of that has nitrogen in its tyres is the Nissan GT-R.
@@MrSupercar55 and probably every Nascar car
@@MrSupercar55 Fun Fact: Nitrogen is also filled in your chips packets, because it doesn't react with oil in it.
MrSupercar55 I have a freaking Mirage and use nitrogen. Anyone ask their tire tech for it. It’s only a few bucks more and well worth it for stable tire pressure.
@@user-xx7pg3vw9k It is "inert", at least under normal pressure and temperature. But it doesn't make any difference on its expansion with heat. The main reason for using nitrogen in tyres is, any moisture has been removed from it during the production/compression. It is the moisture in normal atmospheric air causing all the problems mainly excessive pressure fluctuation with temperature changes. Added (marginal) benefits of nitrogen are a slightly less weight and more safety in case of a fire.

You should worry much more about the tire because there aren't any cases of wings falling off and if the engine catches on fire, you've got another one.
@@smasheduptoaster9186 I rarely heard plane tires bursting, almost like never, only stuck gears/hydraulics which prevented the tires from positioning correctly upon landing.
I would also worry more on engines failing than the tires. Imagine if you're flying in the middle of pacific and both engines failed.
@@iamwisdomsky That would be scary but it's not worrying because it's so unlikely. And landing gear failures aren't a big deal either. They happen every so often without any injuries. And a burst tire is very common. You just don't hear about it because it's not newsworthy.
Nice work.

Thank you for the comparison to a water melon. I was so silly thinking those were water melons on the bottom of the plane!!

The braking system uses Anti-skid which prevents the tires locking when the brakes are applied thus avoiding blown tires. Seen many tire blow on landing and takeoff. An example was the Continental DC10 blowing a couple of tires on takeoff at LAX in the 80s. Captain on his retirement flight decided to abort takeoff instead of taking off which could have made the accident worse.

GP2 engine...
They didnt deflate the tires to reduce the chance of exploding, the wheel and tire are 2 separate things. They reduce the tire pressure so the tire becomes softer and it lifts a little bit off of the ground, making it easier to slide off the hub. Its the same trick diesel mechanics use when they need to change a trucks tire.
The AMM specifically says reduce tyre pressure to lower risk of injury on failure, nothing to do with sliding the wheel off the brake
