I always watch educational videos at least 2 or 3 times to fully understand the subject. Watched yesterday on Autosport, now watching it a couple more times today 😊
Nitrogen is less likely to migrate through tire rubber than is oxygen, which means that your tire pressures will remain more stable over the long term. It's something Nissan utilised when they made the new GT-R.
Hey Chain Bear, great video, interesting as always - thanks. Just a quick request. After Brendon Hartley's crash this weekend at Silverstone, my brain is in a twist trying to work out how wheel tethers work???? What is the mechanic of anchoring the wheels to the car under such extreme circumstances?? How do the tethers not twist as the wheel spins? Thanks - keep up the awesome work :D
Jett Ski basically it’s an extremely strong zylon (fiber) rope that is attached to the brake and wheel assembly. It’s not fixed in the spinning part (rim + tyre) but a static part (brake assembly).
Cheers Willem. So, if I understand correctly, they are not really wheel tethers at all but rather hub tethers. If the wheel is not correctly attached to the hub then it isnt tethered and can still break loose?
That is correct. We have seen incidents this year with tyres not being fitted correctly on the car during a pit stop and the wheel then departing the car independently of the wheel tethers. Those are there to keep the wheel fastened to the car if the suspension fails.
Also the thinner rubber can more easilly lose heat energy to the atmosphere and so less builds up and there's less chance of blisters. (This is the reason cars on worn tyres have more trouble getting heat back into them at safety car restarts.)
I really enjoy watching your new videos, the quality of the animations and models seem to be getting significantly better for each video. I don't know if this is a result of your partnership with Motorsport or not, but either way, keep up the good work!
Suggestion for a video: How they clean/prep the tracks before and/or after races. Could also talk about what (if anything) they do differently for the "proper" race tracks vs the street tracks.
Good video, really informative! Personally I do like the thick tyres, since it is harder to manage you actually see teams rewarded for building a better fitting car (Ferrari) and managing it better (Verstappen, but Kimi and Vettel aswell). Thus making for a more exciting race.
Tiliad is obvious that this tires help Mercedes .. pirelli said the compound is the same ... But like Vettel said... By shaving a bit the tires become harder and the video shows it lol and Mercedes love harder compound
Javier Javier I completely agree with you, I said that I liked the thicker tyres. By which I do mean that I dont like the thinner tyres. However Vettel admitted that the thinner tyres are still better than thicker ones. But just watch the video, since it already stated all of that..
Tiliad I was just adding... Not refuting to your comment..for those circuits it help with the degradation... Vettel himself said that is not brainer if you take a layer is becomes harder cuz it stretch less... And we all know who does better with harder tires
They could put microscopic thermally conductive particles in the rubber mixture to allow heat to spread more evenly throughout the tire. This would help mitigate blistering. They could also use a dye that captures heat and releases it as light.
love the channel! couple the info I gain from your and SuperGT's channel to give me one hell of a time on Forza!! You two helped me discover a passion I never thought i'd have :)
Hey Chain Bear F1, i love your explanation videos! Could you also explain 'clipping'? I've heard that term a lot lately but i cant find a proper explanation for what it is. Cheers!
They need to stop trying to force pit stops with the tires. Do that with the fuel tanks. Making the tires fragile only robs us of racing. No one can attack another car for more than 5 laps without destroying their entire race. So they don't. If they can't pass easily right away they back off and wait the entire race before going for it in the last 5 laps. Make the tires durable, make them use 2 out of 3 compounds, and make them have to stop 2 or 3 times for fuel. And then they'll be able to race hard with light cars and tires that don't disintegrate as soon as the driver tries to push.
Thanks for another informative video. The entropic force can also be seen in simple rubber bands. I have one question that I always pondered about and that is why do they not use the wires in the tyre structure to also warm up the tyres when it is not at optimal temperature.
@Chain Bear F1. Are 'one stop' races becoming more common? In that I mean the teams target a one stop race, excluding unforeseen events. Seems like two-stoppers are less common now. esspecially this season.
Bฺlistering makes races unpredictable, yes, but in the long run it's making races an artificial speculation. Instead of competing and pushing their limits, drivers end up having to nurse the tires and pray they won't randomly fail or explode on them. No team and no driver wants unreliable equipment in their cars.
I hate it. I don't watch F1 to see drivers carefully drive around the track and destroy their tires if they try to go too fast. Sure, occasionally, the stars align and it creates some excitement. It's usually when it rains in practice and the teams don't have any data that it's unpredictable. But more often than not it just ruins the racing. I'd rather see good racing tires but small fuel tanks to force pit stops.
I think blistering is a good thing for the races. It made Austria a very exciting and unpredictible race. I'd prefer they won't bring these low blistering tyres and give us more action and pitsops. It also shows the different styles of driving with low tyre ware or high much better.
Basic science here. Less flexibility means lesser slip angles means less peak coefficient of friction means less grip according to most books. Bit confused here.
Does this also affect traction in high-load situations? Is it possible the tire shaving was a component in some of the surprising traction events we saw in Britain?
Has F1 ever considered allowing multi compound tires like Moto GP uses? Well not exactly like moto gp where the center is one compound and the outer treads are another, but perhaps a soft outer layer with a harder layer under it...?
That's just the frame rate of the camera not synchronized with the tyres. F1 cameras operate at 50 Hz, so if the tyre paint looks as if it isn't moving, that means that the rotation of the tyre line up perfectly with the refresh rate (50 Hz, 100 Hz, etc).
This is an illusion caused when filming something that is rotating. because the camera takes pictures at a given interval the brain starts understanding it as going backwards as the change in position of the wheel moves closer to the opposite direction. Google it! :D
I’m still loving these videos, but I think they are starting to get a bit too complicated. I subscribed because I enjoyed how you could explain something in such a simple yet informative way. This video, not as much, but I had to watch the MGU-K video in particular a few times to understand it. I don’t know, maybe it’s just my relatively younger age, I haven’t been through some of this science stuff at school yet, but anyway. Just a little bit of feedback.
It only makes that much of a difference because it is F1 (or at any racing it would make a big difference), for you normal car, you wouldn't notice any difference.
The tires in F1 are the best in motorsport, so they are very expensive. And yes, a pit stop costs a lot of time. 2 stop strategies are the fastest, while one stop strategies rely more on endurance and constant lap times.
Jozsef Molnar Redfox If all the teams pit twice, wouldn't it neutralise the time lost? Yes, a couple of the teams might pull of a one stopper since they may be more gentle on the tyres but that's the variable.
Thats were the price comes in. Another thing is that the teams only have a limited number of sets to use during a race weekend. The most sets are used in FP and qualifying, which forces the teams to use a maximum of 3 sets per race (assuming they use a 2-stop-stategy) First set -> start to 1st pit stop Second set -> 1st to 2nd pit stop Third set -> 2nd pit stop to finish
You didn't understand what the point of reducing the tread depth was. With a normal tire on those tracks, the tire deforms too much, that means that it heats up very quickly, and blisters while it is still relatively new, just some laps I would guess. Cars would have to drive with destroyed tires with all the risk it involves.
I'm so confused, how can 0.4mm help? Surely that's less than one laps worth of rubber and thinner than a sheet of paper. I just can't get my head around how an insignificant thickness of rubber would change so much. If it was 4mm I would be like ok yeah, makes sense but a 10th of that thickness boggles my brain.
Why didn't Pirelli just bring harder set of tyres instead of modifying the existing ones? I think there is no consistency in modifying a tyre with which all the other races are made. Wouldn't a harder set of tyres achieve the same goal? For example they could bring in Silverstone M/H/SH (which btw we will never see though the year)?
Catrik Well, because modifying the tyre itself is a quite less elegant solution than using a different set of exsisting thres. F1 tyres are made in a certain way and it should stay the same for the whole championship. Who cares if they are slower they are equal for everyone, and also equal to the tyres used in other races
Everyone has equal chance to shave their tires. "who cares if they are slower" yeah well why don't we race with shopping trolleys then, who cares if they are slower, they are safer and cheaper :D
What happened to Pirelli choosing tyres to get 2 stop races this year? www.motorsport.com/f1/news/f1-set-for-return-to-two-stop-races-in-2018-says-pirelli-984761/ So far out of 10 races they have only managed to get the majority of the field doing 2 or more stops 3 times. I would have thought if they were aiming for 2 stop races we should get the majority 2 stop a few 1 stop and a few 3 stop races when they overshoot. I know cars can push the tyres further and Pirelli won't have all the data. But their success at this stated objective seems to be poor at present and if anything they are getting worse.
Thanks for coming to watch even if you've already seen it! It helps!
I might add a bonus 30 sec to future vids to make it worth visiting ;)
I always watch educational videos at least 2 or 3 times to fully understand the subject. Watched yesterday on Autosport, now watching it a couple more times today 😊
Why are the tyres filled with Nitrogen and not with normal air?
How is it so easy to understand from you?
Nitrogen is less likely to migrate through tire rubber than is oxygen, which means that your tire pressures will remain more stable over the long term. It's something Nissan utilised when they made the new GT-R.
So Chain Bear. If by using these thinner gauge tyres, would Low Profile tyres reduce the chances of blistering even more so?
omg the ruler explanation was perfect
I thought that until the shorter piece produced a lower note
I'm wondering how the producer makes the cartoon ruler warbling so real. Amazing!
Audio in this video really professional sounding
Great video. Amazing to think that such a tiny thin sliver of difference in thickness has such a profound real-world difference in performance.
Hey Chain Bear, great video, interesting as always - thanks. Just a quick request.

Jett Ski if course. if it is attached to the wheel, how long would it take to change the tyre?
That is correct. We have seen incidents this year with tyres not being fitted correctly on the car during a pit stop and the wheel then departing the car independently of the wheel tethers. Those are there to keep the wheel fastened to the car if the suspension fails.
th-cam.com/video/38dmxY1o2C4/w-d-xo.html
Would recommend this video from Motorsport tv on the wheel tethers
Congratulations on the partnership with motorsport.
Not a bad association between motorsport and chain bear. I love how they both go into details of the f1 car and also the tracks.
Brilliant video!
Seniac YOUUU
Better than yours pal
Spaghetti Man true
i love it when you see youtubers that you think wouldnt even think about the topic but here they are
Also the thinner rubber can more easilly lose heat energy to the atmosphere and so less builds up and there's less chance of blisters. (This is the reason cars on worn tyres have more trouble getting heat back into them at safety car restarts.)
I love your videos! It has made watching F1 so much more fun than before, knowing what's actually happening with the car. Keep it the good work! :)
thank you for putting together content that i can then use to act like an retired f1 engineer to my friends
This is an excellent video. You explain everything very well amd detailed without it getting boring! Your channel is awesome!
I really enjoy watching your new videos, the quality of the animations and models seem to be getting significantly better for each video. I don't know if this is a result of your partnership with Motorsport or not, but either way, keep up the good work!
Another brilliant video from our Chain Bear
Caught it on Autosport but watched it again anyway. Congrats, and hope to see you continue to get more work like that
I didn't realize i watched your video in autosport channel until i read the comments.. congratulation!
It was weird seeing this on autosport but at the same time, good for you!
Once again, a very informative video! Thanks you for this Chain Bear!
Thanks for another video.
Greetings from Spain.
Liberty media should pay you for your vids, great simple explanations. With nice graphics.
Your videos are amazing dude !
Again, very helpful and simple animation. You should consider making a video on "How To Explain Things" bc you're really good at it.
Suggestion for a video: How they clean/prep the tracks before and/or after races. Could also talk about what (if anything) they do differently for the "proper" race tracks vs the street tracks.
Good video, really informative!

They could also use a dye that captures heat and releases it as light.
I finally know why a tire blisters now! Thanks!
Ah... i truly do understand now; thanks a million, CBF1! And yes, I too think Pirelli is wrong to try and keep _everyone_ happy...
Best youtubing youtuber on youtube
love the channel! couple the info I gain from your and SuperGT's channel to give me one hell of a time on Forza!! You two helped me discover a passion I never thought i'd have :)
Best vid yet
Love these videos, outro rocks by the way
Another fantastic video I think I’m going to patreon you
Was actually just wondering how thinner = less blistering, but ofc I forgot about wear and it leading to an earlier pitstop haha great video 👌
great explanation again.
Great audio effects
Great video!
great video, i would love to see a comparison with tyre graining
Keep making awesome videos and maybe one day they'll stamp your name on the tyre sidewalls for real.
Last time i was this early hamilton was still 17th place
Hey Chain Bear F1, i love your explanation videos!
Could you also explain 'clipping'? I've heard that term a lot lately but i cant find a proper explanation for what it is.

awsome! amazing video! unbilivable
Suggestion: Could you do a video on sound analysis in F1? Excellent channel!!
good stuff sir!
Very well explained ... question pops up tho .. Are teams allowed to "shave" their own tires if the thin-threaded aren't used over a weekend ??
Tailored for Mercedes! Special tires ;-)
Congratulation!!!!
Whatever you've changed with the audio is working.
Am I the only one that likes all of this thermal degradation and blistering? It's made the Austrian and British GP absolutely amazing.
I dido too, fun to watch.
Bฺlistering makes races unpredictable, yes, but in the long run it's making races an artificial speculation. Instead of competing and pushing their limits, drivers end up having to nurse the tires and pray they won't randomly fail or explode on them.

I'd rather see good racing tires but small fuel tanks to force pit stops.
please make a overcut explain video
Yes, please!
EDIT: Also undercut
Can you do a video on how safety car starts/rolling starts work?
love the videos
I think blistering is a good thing for the races. It made Austria a very exciting and unpredictible race.
I'd prefer they won't bring these low blistering tyres and give us more action and pitsops.
It also shows the different styles of driving with low tyre ware or high much better.
Thanks a lot!
hmmm Tire Philosophy... sounds sophisticated
Basic science here.
Less flexibility means lesser slip angles means less peak coefficient of friction means less grip according to most books.
Bit confused here.
Yay yay I'm in the end credits :)
Great video :)
All your videos are crazy insightful and helpful! Thanks a lot, really!
Here after the Mercs blistered badly in the 70th anniversary GP
Just great
please make a video explaining the effect of larger rims
Does this also affect traction in high-load situations? Is it possible the tire shaving was a component in some of the surprising traction events we saw in Britain?
It would have been nice to know how much the tires have usable tread to begin with!
does this count as a repost?
According to people who watch AutoSport, and PeterWindsor yes!
I did not know. Cheers.
Epic!! Are studying engineering at university?
Is this a re-upload? I could have sworn I watched this video yesterday. Did you have to take it down and put it back up?
TheSpacecraftX you probably saw it on Autosport
James Gowan crap I watched it thinking it was from chain bear without looking at the channel!
Wow yeah I did the same. Just assumed it was Chain Bear.
Chain Bear is so cute
Has F1 ever considered allowing multi compound tires like Moto GP uses? Well not exactly like moto gp where the center is one compound and the outer treads are another, but perhaps a soft outer layer with a harder layer under it...?
Other channels: did Kimi crash into Hamilton on purpose?
Chainbear: where did that 0.4mm go, and why?
Asking the real questions ;)
How thick is the tread of an F1 tyre normally?
Video on why the paint on the tyre wall seems to rotate in the opposite direction when travelling at high speeds
That's just the frame rate of the camera not synchronized with the tyres.
F1 cameras operate at 50 Hz, so if the tyre paint looks as if it isn't moving, that means that the rotation of the tyre line up perfectly with the refresh rate (50 Hz, 100 Hz, etc).
This is an illusion caused when filming something that is rotating. because the camera takes pictures at a given interval the brain starts understanding it as going backwards as the change in position of the wheel moves closer to the opposite direction. Google it! :D
you can actually calculate the speed of the car by multiplying 50 or 100 Hz by 2*pi and the radius of the tyre.
already watched this in Autosport ;)
What about forcing at least 2 pit stop per race so we can get an ever pushing hard competition? No compounds boundaries tho
I’m still loving these videos, but I think they are starting to get a bit too complicated. I subscribed because I enjoyed how you could explain something in such a simple yet informative way.

thanks, I'll bear that in mind. My aim is to try and keep them accessible for the absolute layperson :)
It’s just me or is it astonishing that 0.4mm make that huge of a difference?
It only makes that much of a difference because it is F1 (or at any racing it would make a big difference), for you normal car, you wouldn't notice any difference.
New microphone? Or just me thinking audio is different
Do a video about formation lap
i think thinner tires would be nice so the drives have to stop 2 times. that would give a bit more fun in strategy
Why not make it 2/3 pit stops to reduce the usage of the tyres, instead of bringing these reduced tread depth tyres?
Pavan kumar pitting 2 or 3 times would cost too much time.
The tires in F1 are the best in motorsport, so they are very expensive. And yes, a pit stop costs a lot of time. 2 stop strategies are the fastest, while one stop strategies rely more on endurance and constant lap times.

If F1 was a Uni degree, you'd help me pass it!
You did this at AutoSport
Why you upload at Autosport first?
Is it a reupload?? Why do i feel like i've watched this lol
Or you move the atoms when springs move and atom movement is heat, more simply
Fucking amazing content
Wow! You sound exactly like the narrator from the latest Autosport video on the same subject.
(Yes, its a joke.)
I'm so confused, how can 0.4mm help? Surely that's less than one laps worth of rubber and thinner than a sheet of paper.

Is it me or you changed the speed at which you speak?
Great video but is it just me that thinks he sounds different from previous videos?
Although it's less than what it used to be, you still have little stops between words
