Technical correction: The Boeing 737-800 main wheels (the 4 rear wheels) are actually 44 inches making them just barely larger than the tractor trailer tire. Despite my research and having a second engineer fact check the video we both managed to miss this fact because the nose wheel diameter is 27" and mentioned in more places. The overall story is the same. The capacity of the airplane tire is many times greater than a truck... including the 27" nose wheel, but it was definitely worth mentioning that not ALL of the tires are 27". Unfortunately I can’t change the video now that it’s live. I also added this note to the description.

the mains support most of the weight and the plane lands on the mains, nosewheel landings are bad, even in small planes. main idea is that with six tires on a '37 the two in front don't carry 33% of the weight, probably about 10% so the four mains carry 90% and they do all of the braking since there are no nosewheel brakes (I believe that the 727 had these on some models). You might also exhibit the cages used when tires are inflated (they sometimes explode) and I believe there are videos of this actually happening, truck tires also explode and they sometimes use a safety cage for inflation. The brakes have to demonstrate the ability to stop the plane from takeoff speed at full load within a given distance without using reverse thrust (situation, an aborted takeoff at the last instance (V1) due to engine failure), this would involve stopping 150,000 #s going 150 mph within less than half a mile. When this happens operationally, the plane will normally stop on the runway while the fire crew stands by making sure the tires don't catch fire and the plane will have to wait a substantial amount of time before trying to take off again and might require a technician to check the brakes and tires before doing so. Don't sweat your error in tire size, this was a very good article. Thank you.

Also, the fuesable plugs are in the wheels, not the tires as you say in the video, Minor nitpick I know. Great video regardless. On most if not all aircraft, there is very little weight on the nose wheels. This is a problem for many aircraft. In fact, certain aircraft with tail mounted engines have been known to tip backwards just from the weight of snow from a storm.

I am a Retired USCG Aircraft Mechanic / Flight Crewman. I worked the Tire Shop at one of my assignments and built up and balanced hundreds of jet and helicopter tires. Thank You Jeremy for diving into this very critical component of flight. BTW we flew on the same aircraft we worked on and if we broke down some where we just called "Home Plate" and they shipped / delivered via another aircraft to us the parts we needed to fix our aircraft. We performed ALL the repairs and Maintenance on our aircraft. There where no outside Repairman to call, we was them. Keep in mind the HC-130 can taxi over sand, like in sand dunes type sand with a lower tire pressure on the mains (100psi) and still have a takeoff weight of 165,000 lbs, think of an elephants foot vs. a goat's hoof.

Yes, but you also have a lot more wheel assemblies to allow that operation off of unimproved surfaces. I have seen pilots scrub every one of those wheel assemblies to replace level in a single landing, thankful I was not the one changing them. My next door shop was the wheel bay, he had his own nice little armoured room, far from everything breakable, where he would do the first fill of any wheel assembly. Concrete walls and floor, and armoured door, but frangible roof so the blast would go up. Just like the armourers had a similar room where they would fuse munitions, for the same reason. Armourers had the best door gargoyles though, recovered practise bombs that were mostly intact, though the 1in steel case had split open and become more or less flat.

Lots of carbon black in the rubber, and till recently carbon loaded grease in the bearings, so they will not have arcing with the discharge. They have changed the grease formulas as well, so as to add in molybenum and other anti wear additives as well, to reduce the wear from the carbon on the bearing surfaces. The straight carbon loaded black grease is suprisingly abrasive, due to the carbon in it, but you do need a conductive grease that both will not build up, but also allow the bearings to spin freely at high speed, even with massive shock loading and temperature swings. Hard act to do, so there are a lot of specialty greases used by each manufacturer, all slightly different, and not always interchangeable

When I was in engineering school (a million years ago) our Dean hijacked one our our lectures and asked us a single question: "You've been in university for several years, can you tell me, what is an engineer?" After listening to our responses for an hour, he said "You told me what an engineer DOES, but not what an engineer IS." After a few minutes he answered his own question: "An engineer is someone who does something 'just right'." He then elaborated about how engineers always have to balance conflicting drivers to achieve an optimum balance. Not maximum, but optimum. He was right. That was one of the most important lessons that I learned and that I applied over a long career in heavy industry. Now, I'm enjoying a second career as an associate professor, and you can be certain that I tell my students that same story and repeatedly remind them that engineering is all about compromise and optimization. Thank you for your videos - they are well researched, well presented and entertaining as well.

Great video! Great to see your son shares your enthusiasm. Heavy jets have higher speed ratings for their tires. The speed rating is marked on the tire. Strangely, all speeds for pilots and ATC are in knots (nautical miles per hour) but the tire speeds are marked in statute mph. Most of the 737s I've flown had 215 MPH tires while the heavier jets I've flown (767-332ER) had 235 mph tires. In the 767 at max weight you would normally liftoff close to V2, about 170 kts or (170X1.15= 195 mph) so there's a good margin in case you need to perform a partial or no flap landing with higher approach speeds. Finally, another benefit of higher tire pressure is hydroplaning. The types of hydroplaning are viscous, reverted rubber and dynamic. Dynamic hydroplaning occurs with water on the runway and it's 8.7 times the square root of the tire pressure for speed in knots. A 200 PSI tire will hydroplane at about 123 knots. For statute mph a good estimate is 9 times the square root of the tire pressure so a 38PSI tire will hydroplane at about 55mph. Cheers

Fascinating topic! I learned a lot from this video. One thing that comes to mind about tire size is rotational inertia. It takes less energy to get a small tire spinning than a large one. That suggests it takes less friction on landing to get the tire spinning.

the irony is that those tires can't handle the high speeds cars are capable off. About 170 mph they can start to rip apart. most commercial and military acft land around 120 to 140 mph so there isn't a need to increase the cost to cover much higher speeds than that.

Jeremy, another excellent discussion One point I would make is the distribution of the weight on the mains vs the nose is significant. In the A/C I work on the BOW is around 50,000lbs the mains carry about 23-24 k lbs and the nose about 4-5k lbs when on the scales for weight and balance calculations. Nose tires about 120 psi and mains 200 psi we only use dry nitrogen to service. I love your passion keep up the good work

Agreed. There are other details like this I left out on purpose. For example tires that don't have brakes aren't "required" (according to the 1990's report I show in the video) to use nitrogen but I felt like I reached a point where too much detail made it less interesting and harder to follow.

I think this would be a really good collab. Most of the reason they these tires can be engineered the way they do is the enormous engineering that goes into airfield pavements. I do airfield engineering work for a living, and even if you could get the same tire onto a semi ignoring the changes in how the tire is used, the road would just disintegrate below the truck. Military airfields are routinely 16” of the highest strength concrete available. I think a practical engineering collab on that side would be so cool.

I work on the ramp with Airbus A320's and A319's. The tires are much smaller than I first expected, and the gear assembly is massive! Reverse thrust help a lot with braking, allowing tires to be even smaller. The conductivity also reduces static charge to reduce chances of fire when fueling, and there are also big fans integrated into the hub assembly of the tire to help expel heat! On a cold day it's nice to stand next to it :)

Currently a line maintenance technician for the largest air cargo airline. Aircraft tires are extremely heavy. A main tire for a DC-10 and MD-11, 54 inches in diameter, weighs about 600 lbs with an extremely light magnesium wheel. They are rated for 235 mph. The tread profile of the tire is over an inch thick. The tires get beat all to hell depending on the type of runway they operate from. It is truly amazing how strong aircraft tires are.

In some cases, there must be incredible counterforces, and a worm drive doesn't seem to be (to me) reactive/quick enough to do the job, although obviously it does. Nice video!

Good video, thanks. A side benefit to higher tire pressures is the increased speed before it hydroplanes. And while the tires must support the weight of the airplane, we have all been on landings that just slammed into the runway, so temporary higher loading. If there is a stiff crosswind the tire takes large side loading. Like you said, incredible tire design.

I’ve seen a couple of your videos now and thank you for them, sir! Especially this one interested me as I just crave knowledge in general. I’ve always kept that childhood wonder and amazement with large machines and the sheer miracle of flight, but never put much real thought toward the tires having to endure what they do. Thanks again Jeremy, sub well earned!

I work for an automotive plastics manufacturer in the testing lab. We make nothing so critical as an airplane tire, but the level of scrutiny applied to mundane parts such as trim pieces is incredible. I cannot imagine the testing required for aircraft parts.

Jeremy, thanks for this information. Just two adds to what you said. One, the grooves are called sipes. There's a good bunch of information on that. Second, used commercial aircraft tires can be used on various agricultural applications. One that comes to mind is manure spreaders. I have used commuter aircraft tires on carts, and they work well with go-kart rims. The two most common sizes I use are 5" and 6". As you mentioned, split wheels are required for these as well, for one fundamental reason. Instead of steel cords in the bead, these have a steel ring that keeps it's shape under varying circumstances. The tires are definitely overrated for my applications, but when they are deemed not flight worthy, there are further uses beyond that.
