F1 tyres sometimes go bang in spectacular fashion.
They can be fine for 50 laps, then explode with no warning, all while the driver is doing 180 miles per hour into a corner.
But why? What is really happening when a tyre gives up?
Today we’re going to look into some of the most INSANE tyre explosions and how F1 cars manage to literally RIP THEIR TYRES APART.
If you’re a long-time F1 fan, you’ll know that the tyres break pretty frequently.
This can happen in a number of interesting ways and we’re going to go over that. But first, to understand why they go bang, let me explain how they’re put together.
A Formula 1 tyre is made up of a mixture of synthetic and natural rubbers, combined with other materials like Carbon Black that are layered and then cured in a mould under extreme heat and pressure.
This intense heat and pressure produces a reaction between the materials that combines their short chains of molecules into longer ones, creating the tyre compound.
These longer chains give the tyre the elasticity to cope, [most of the time] with the extreme loads of F1.
This compound is supported by a mixture of kevlar, nylon and polyester that makes up the sidewall, the carcass and the tread around the outside of the tyre.
This helps the tyre withstand incredible loading under acceleration, braking and turning.
And finally, the tyre is not filled with air, they are actually inflated with dry nitrogen gas. This is because when air gets warm, it changes its volume more than nitrogen, meaning tyre pressures also change.
Using nitrogen means the tyre pressures are much more consistent.

My friend was Nigel’s babysitter in 1986. She was with his kids at home staying up late watching their daddy race in Adelaide. Within seconds of the crash Nigel had borrowed a mobile phone from someone by the track and called them to say he was fine. Then he talked to his pit crew.
Nice story. Did he live on the Isle of Man at that time?
@@TrevorDennis100 yes
Hey thanks for that anecdote! Love such fun facts
Cool story given that “handheld” mobile telephony wasn’t available in Australia until 1987. Prior to that it was car phones only, and VERY limited in availability, 😂
@@kayjay7585 It reminded me of another story about Nigel. Apparently he was a bit up himself and was the only driver to have a bodyguard, who even had to accompany Nigel to the toilet.
I remember that terrifying puncture Max Verstappen had on the straight at Baku 😅
Yeah when Ricciardo's front wing slammed into the tyre.
Oh shit you're talking about 2021.
Happened to Stroll earlier in the race also. Thankfully he was at the start of the straight seeing as he veered towards the pitlane wall.
@@rahulravishankar3152 lol typical fanboy response. Definitely not max's fault, he didn't move twice under braking there no siree
@@turbo_brian Looks like someone's living in your head rent free. Can't even joke about Baku 2018 without someone aggressively shitting on you for being a fanboy smh.
@@rahulravishankar3152 right.. because Brian was the one who connected Baku to Ricciardo in the first place🙄
Wow, I did not know au rouge was that great in elavation. 12 floors in like 3 seconds! Great visualisation.
On the topic of tyres, can you do a video on why the Michelin tires failed at the 2005 Indy GP?
Not strong enough sidewall iirc,Bridgestone already had data from Indycar to use special tires there
chainbear has a pretty good video about it!
@@luigico8657 oh! I haven't seen. I will check it out soon.
theres like a thousand videos on it
@@milk3013 I prefer Driver61's. It just sounds nicer, and the clips keep me in. I'm not too sure why either.
I remember Lewis Hamilton had a spectacular tyre failure in Turkey 2007. Bridgestone, the lone tyre supplier at the time, reported that drivers (Hamilton in particular) suffered from chunking. The chunking was caused by the combination of his driving style, the more aggressive tyre usage of his McLaren at the time and the stresses the tyres experience through turn 8. Over time, these caused the rubber compound to separate from the belt of the tyre, hence the chunking. This undermined the ability of the tyre to hold air in it, and in Hamilton's case, it failed under braking for turn 9.
As Istanbul Park is an anticlockwise layout, this meant that the right front tyre was most exposed to this problem and the tyre failure, coupled with the failed tyre flapping around, it led to damage to Hamilton's front wing and he struggled to turn into the pit lane entry. The team changed his tyres but didn't change his damaged front wing. In the end, he finished 5th
Anti clockwise?
You mean, counterclockwise? Lol
@billyyank5807 lol yourself, in my country it's correct to call it anticlockwise
@@billyyank5807 so no, I meant, anticlockwise, I thought you spoke English, lol
I have always said that tires are the most important part of a car (and brakes of course). People dont pay much attention to tires, but a ton of engineering research and development has been done to take drivers from A to B fast and safely. The tire engineering for F1 cars is even more impressive, since these tires take an insane amount of abuse during a race. Well done Pirelli F1 tire engineers!
There's an old tyre advert, I think it was Bridgestone and I remember it in Australia.
Their whole advert was how there is only 4 hand prints (the contract patch size) keeping you and your family safe.
And from memory the ad shows the car stopping just in time as to not Knock over a child.
Emphasizing you need good rubber to stop.
However everyone sees them as black and round so they're all the same.
It's the compounds that matter.
Tyres are absolutely the most important aspect of any car. Braking, cornering and accelerating just wouldn't work without good tyres.
Only a racing driver can say "...but Copse is just a high speed corner..." and keep a straight face.
Genuinely made me chuckle.
Enjoy the content. Keep it up.
2005 United States GP at Indianapolis...Michelin tyres couldn't cope with the banked turn and the entire race turned into a farce with only the six Bridgestone runners taking part.
The most memorable tyre failure occurred when Scott's father, Sir Nigel, was leading the last race of the 1986 AD season in Adelaide and was about to win his first WDC when the his left rear exploded, thereby handing the championship to either Prost or Piquet. His teammate, Piquet, could have won the race and championship but the team decided to bring him in for new tyres. Since Prost had already suffered an earlier puncture, he was on fresher tyres, handing the race and championship to Prost. But 6 years later, the Lion of England, would finally get a deserved World title in the 1992 AD Williams FW14B. But the 1986 AD Williams FW11 is one of my favourite F1 cars and livery. The mid-80's is the golden age of F1.
They are not related. Did you just assume based on the name?
@@Redskies453 I was going to say that.
What are these miles per hour? F1 uses metric system.
Damn imperialists!
Kph would be fine with me but I’m guessing a majority of viewers are located in USA and are casual fans, and if that’s most of your audience, it’s easier for them to understand mph 🤷🏻♂️
stikstof-
Not to mention he used ft when speaking about elevation
Technically we should be using meters per second.
The only thing that probably should have been mention was the centrifugal weight of the tires at different speeds, compounds, & generations of tire.
While all the other stuff that you discussed was happening…. The tire weight getting really heavy & then less heavy. This is where we get our explosion!!!!!
Yes, that's a really good point.
sorry mate but silverstone 2013 Pirelli has revealed four factors behind the failures: mounting rear tyres the wrong way round, with tyres intended for the right rear of the car put on the left; adoption by the teams of too-low pressures; extreme camber settings; and aggressive kerbing at Silverstone.
I was really surprised to see the amount of body roll in the Rosberg shot of Degna 1. Great video!
Tires go thru weird dynamics, the part of tire that is behind axle center line has to speed up to go past center & then slow down to go behind centerline, it is way different than a fan spinning in a circle.
I've only been a fan of F1 for 5 years, never seen, but I will be on the lookout for one this season
2020 British GP Lewis had a blow out on the last lap and just managed to keep the lead.
Everytime Nigel is mentioned I need to hear “not my dad” 😂😅
It’s just so crazy that with all of the parts we use in cars,and different materials,that the most important part is made of rubber and is the contact to the road,which can be very rough and tough,the crazy part comes in because tires simply work (tires as we know them now anyways)!!And this video amplifies how amazing tires are and how we trust tires to do what we need them to do in the applications that we use them for!!
I’ve got myself a tire exploding on a road trip while only traveling 120km/h on semi-rough surface…. and it’s a pretty new tire as well with only about 30.000 km clocked in. I think I can understand if sometimes F1 tire gives up under much higher pressure situation.
30 000 km is in no way pretty new tire. That is more than half of the usable tire life.
What wasn't explained in this video is there are 3 forces acting on the tyre.
Downforce: squishing the tyre
Side force: pushing the tyre of the rim.
Rotating for: rotating the tyre around the rim
When you break and accelerate the force is transferred through the inner diameter of the tyre, whilst the outer diameter is trying to stay put. This is putting rotational torque through the sidewall.
Top fuel dragster are a good example of this.
The other mention is as I don't think FEW are running bead locks. The only thing attaching the tyre to the rim is friction. The air pressure is keeping that friction high, if you lower the tyre pressure there becomes a point where the one or all of the 3 forces are more than the frictional force of the rubber to the rim wall and then the tyre will fail.
Bead locks prevent this, that's why extreme off road vehicles run them, as it's a clamping force and not a frictional force. So can run no pressure and the tyre will stay on.
2:31 ... That's Raidillon actually 😂
he knows it,people commonly refer that section as eau rouge
The annealing links the polymers so a tire is essentially one enormous molecule
Vulcanised?, As I thought that's what vulcanising was.
@@Robert-cu9bm yeah. That’s the right term lol
Actually that is Raidillon! 😂
Can you do a episode about the evolution of the pitwall and remote garage? I think it's a cool subject
At 1:20, either what you're saying, or what you're showing is incorrect - The dispersion rate is the rate at which nitrogen and oxygen will 'leak' out of the tyre (hence why you need to periodically fill up your car's tyres)
4:13 its 27,000hp (20,133kW). Also with brake bias at about 58%, and the front loading of the car, the front tyres are probably doing about 70% of the overall breaking. Or about 9500HP per tyre. kW is a better measurement though. . The total braking of 20MW would power about 30,000 - 40,000 homes for that short period of time (~2s). (an average of 415W - 666W over the 24 hours assuming comfortable temps)
Topic: How much does a driver get to test out the car?
I only got into F1 a year ago, and I don't understand if the drivers can test out their cars as much as they want outside Fp1-3. PreSeason testing, is this the first time a driver can get into the car and take it around the block? Do 3rd drivers etc test out upgrades on the cars at the factory, or is all this done in the windtunnel.
I'd love to find out.
always nice hearing Scott talk about extreme loads >:D
1:40 I would use the long right hander at the start of the Catalunya circuit. You see at the F1 game, the heat and degradation on the front left
Whoa I never knew Eau Rouge was like 12 stories in elevation differences, that's crazy.
Curious how the manufacturer of the tire blamed a phantom problem. A manufacturer that just so happens to supply the tires for the industry where a mysterious failure occurred. Kinda sounds to me like the Inverse Kramer Law should apply.
I'm guessing either the tire had a defect that could have potentially been present in the entire batch or something failed, but not all the way, only just enough to create heat but no sparks yet slowly heat up a rim somehow enough to soften the bead of the tire to the point where the tire failed but again somehow without something else overtly failing like decrease braking power, partially locked wheel, not weird at all.
U hit 1M subs!
Congrats!
Now give us that f1 experience video :)
congrats on the 1M scott! 🎉
2 corrections.
1. Cornering forces haven't been "only" up to 4g. I remember Bottas some years ago in a Mercedes in Silverstone going with 6.2g through the S.
2. Kimi could have changed tyres, of course. But then P1 would have been over. It was a gamble and he lost.
We've seen that gamble a few times over the last couple years.
@@Robert-cu9bm, when?
@@DaveMcIroy Hamilton Vs vestapen... Hamilton could have pitted but didn't, gamble he lost.
And I think it was a recent one with Russell when they realised how long the mediums lasted.
I'm not big on F1, just remember some of the highlights with the commentary saying about the pit strategy.
@@Robert-cu9bm, ahm, that was different. In these incidents the suspension wasn't under threat.
Sir Lewis Hamilton winning on only 3 wheels when his left front tyre exploded at Silverstone in 2020 is a moment I will ALWAYS remember! That was insane. Pure legendary stuff.
Should’ve been penalised for that. If it was any other driver than “SIR” they would’ve been. My cars in my team would’ve been fined for that.
@@robsmithracing New to F1 I see.
Another way tires explode is when you put dynamite on the tire and then light the fuse
How much is 180mph for those that use metric units
All of it.
See you’ve reached a 1 million subscribers. Congratulations!
Any story behind how you arrived with the channel name, Driver61?
Probably because hes a driver, and probably his racing number was 61.. I think he was/is also coaching, but anyway... :DD
Have we seen a tire explode this year? Or even last year?
It seems like these tires are way more stable than 2012 era. George Russel at Spa shows that.
Always watching from Georgetown Guyana south America 🇬🇾🇬🇾🇬🇾
I was watching my hero at the time Nigel Mansell live in that race thinking new world champion when that tyre blew, I was gutted, though probably not as much as he was!
F1 1998: „we need grooves - maybe races will be less boring“
F1 2001: „Michelin“
F1 2005: „no tyre changes“
F1 2007: „Michelin, get lost!“
F1 2009: „bye grooves!“
F1 2010: „Pirelli, my old friend!“
F1 2011: „colors!🎉“
F1 2016: „what?! Worse tyres? Why? More you say? Okay!
Let’s produce complicated, funky degrading tyres and say byebye to reality!“
I’m „tyred“ 🥱
Grooved tires weren't introduced because races were boring. They were introduced in order to slow cars down for safety reasons. And yes, Pirelli ruined F1.
And then McLaren lapped the field at the Australian GP that year. So much for slowing the cars down!
"bono! My tyres are gone!"
I've always thought it fascinating that rubber and hence tyres allow the world around us to keep moving - I then wonder where things would be if the limiting factor for motorised vehicles was the old steel banded wheels 🤔
Sorry, Can you making a video about how Mercedes can kept their engine under operating temp with less area of side pod or packed with the area inside the pod, Thank you.
It's Pirelli tires as opposed to Michelin tires i.e. WEC LeMans 24 hours.
Michelin have a different ethos when it comes to motorsport.....they don't believe in various compounds like hard, medium and soft compounds like Pirelli in F1.
Raikkonen had the option to come in for a tyre change in 2005, he opted to stay out as he was on for a win.
It was in the regs for safety reasons, although Mclaren might have had to risk a penalty if the FIA deemed it wasn't justified, but I think the subsequent events showed it would have been justified on safety grounds.
This is the commentary from the time, ruclips.net/video/SVO_qMoB7xE/видео.html
just wanted to say I prefered the first thumbnail without the red circle!
Could you please include metric measurement in some form or way. With text in the screen?
Thats the smoothest transition to an ad I have ever seen😮
Yeah big over look is the hot hybrid recovery systems with their shieled an less ventilation hopefully they changed that for the new seasin..i didnt like thst closed off front inside of the rims...for wake controll needed more opening for releasing heat....!!!!!!
Would be able to do a video on the reason that Kimi Raikkonen doesn't warm his tires up.
Before watching the video: Considering the strains they are under I'm don't grasp how they stay together at all. Tire tech is astonishing these days.
Fun fact about Rosberg's picture: It's NOT a push lap.
Thanks 👍
Oh, this happens to other vehicles as well. Have 2 exploded tyres on my truck story :D
Why when they make contact with another drivers wheels do you see a small flame right as they burst?
Are you a bicyclist as well? Just noticing your Rapha hoodie while the AG commercial
Love your channel and take on things
thank God driver61 still has the same host not like other said channels...
Oh mylanta I'm as gutted about the change as anyone else but keep it out of other channels. Geeeeez.
1 Million !!!!
On a related note, could an F1 driver drive with a slow puncture
Ask Schumacher...
I'm surprised they are using kevlar instead of vectran
I never get tired of learning about Tyres.🎉🙈👍
Once you're done with that you can learn about Tires.
@@Robert-cu9bm Dang imperiast! 🫣🤪
3:20 are we sure that's Nico Rosberg? I'm told that he and Hamilton had equal machinery in 2016...
Tires are truly underrated we forget how much abuse we puy them thru its really a skill if today a driver could make them last longer...because the F1 race is a sprint no fuel race
Since Bridgestone won't say it here, I will.... Bridgestone's tyres / tires over in IndyCar have gone years... over a decade?.... without such a failure. Heavier cars, on ovals where there are faster constant speeds than most F1 top speeds, etc etc. Perhaps the problem here isn't with tyres, but rather the FIA's spec that makes them fragile?
Gostava mais do tempo que avia briga entre fabricantes de pneus na F1, por isso a Michelin saiu não adianta investir se não pode mostrar que seu produto é melhor.
Low pressure is what cause the Firestone tire failures on 1st gen Ford Explorers.
It sure was a factor but not the only cause
thanks for the video
Common occurrence over here in the NASCAR world unfortunately
Turkey's 🇹🇷 3 left turns put the Tires in tremendous stress
Nice Rapha hoodie! Sent you a request to follow on Strava.
1MILLION! RELEASE THE VIDEO OF THE FAN DIRVING AN F1 CAR
Bono my tires are gone
Literally.
Pirelli ''investigating'' their own tires should not be allowed.
Great video
shoot for last place that will be easier on the tires
bruh went from miles per hour to kg next shot lmao
Damn that was a good Segway into the sponsor
It's "segue." They brand Segway got its name from the actual word.
i think a more acurate title would be [F1 tires are victims of torture]
These tires are amazing. The technology is all passed down to our passenger cars. You don't see too many blown tires anymore.
Also, congratulations on 1M subs. I look forward to seeing your gold button plague.
Not to mention they can now handle faster speeds and handling. All while lasting longer.
Thank you for using my video at 2.46
What? at 2:43
What happened with Ricky? (the F1 experience winner)
"pretty frequently"??? Surely they can only go bang once
I see Scarbs is on vacation.
Jo bro now we have 1mil subs when is the video coming of an non experienced driver driving an f1 car?
a video suggestion: talk about f1 tires
I may never understand how forced deceleration (braking) equals power output.
the KERS system, I can’t get too technical into how it works cause I don’t honestly know lol but it basically stores some of the energy from braking to use for acceleration.. would be a sweet vid if he explained it better/ in more detail but that’s a general idea
Why is it that drift car tyres don't seem to lock up in the same spot when they use the second caliper to start a drift, I remember seeing Nigel's tyre blow out and later he was told he would have won if he wasn't able to not crash.
Drift cars don't use such a soft compound as F1. As well, purposefully spinning the tires should help to even out potential flat spotting.
@@Vykk_Draygo
I do wonder how soft a soft tyre for f1 is.
It may be soft for f1 but the forces acting on them, they can't be that soft.
Mph?! Damn
The actual answer to the question in the title is that the tires are deliberately designed to fail prematurely, in order to force the prescribed number of pit-stop. Sometimes they fail too prematurely
Hey scott. Are you ok? Looks like you got a black eye (your left). I mean that genuinely. Hope everything is good!
3:32 "3 g of lateral load"
A 'g' is an acceleration, not a force/load.
3:35 "2 tonnes of downforce"
A tonne is a mass, not a force.
As for drivers standing on the brakes (3:59) "and I _do mean_ standing" - I have never seen drivers shift from the recumbent position to the vertical when cornering.
Ooo recumbent, you’re totally not a tart
I think everyone else who watched this video understood just fine. It is a "you" problem.
Get above 140kph on a set of mud tyres and things get really interesting...
Good call on the thumbnail change
It's interesting that you rarely see tire failures in Indycar. I think they put safety above performance more than F1.
Don't indycars have less downforce and power? I'm pretty sure that these factors put much less load on the tyres.
IIRC. FIA set a spec for F1 tyre to make racing more dramatic. And the result of that F1 tyre will go downhill at a certain point for each compound.
@@mixswist yeah apparently it's a bit hard to make tyres that are durable enough while at the same time last so short distances, that's also surely a factor.
I don't think so there is major speed and compounds difference
@@wombat4191 2005 Indy GP. I also remember the backside of a curb at a British GP cutting through the sidewalls and rupturing the tires. Tire failure is not the same as wearing the surface out. In the past, Indy/CART was pushing over 900 hp.
Seems like the FIA cost Kimi that race in 2005 and potentially put him in harm's way.
@Scott, are you a cyclist? I saw you're wearing a Rapha hoodie. Seems there are a lot of motorsports guys who are cyclists.
thought i was listening to a joe rogan podcast when the AG add came on
