Couldn't find a thread for everyone's favourite tyre company.

 

Pirelli released the compounds for every race for the F1 season. 8 softs, 3 mediums and 2 hards used at each race

 

Azerbaijan and Brazil a step softer than 2019.

I wish they would skip tyre compounds like they used to from time to time. Would spice up things a bit. 

 

Will be interesting how things work if these sprint races go ahead too.

everyone's favourite tyre company.

Nothing against Pirelli but I'd rather have Michelin tyres on my car. They were kicked out of F1 for making them too durable

[TomNokoe]

My tyre wishlist:

1. Drop the C1 compound
2. Revert back to two dry compounds per GP
3. Introduce compound gaps on occasion
4. Scrap the Q2 tyre rule

(i.e. basically what we had from 2007-2014)

Having only five compounds in the range and bringing any given three to a race is far too wide a selection. The hardest compound at any given race is often capable of three quarters distance.

We need races to be run on the Soft and Medium for more pitstops and "better" strategies. They will never scrap the three compound rule because 3>2, so I suppose all they can really do is make the hardest compound two steps harder than the Medium, as to discourage the teams from using it.

You hear quite often "just bring softer compounds!", but you can't turn up at Spa with the C5, it's unrepresentative and probably dangerous.

From the announced selection and historical data, barring weather, VSC/SC, crazy tyre pressures, it will be 1 stops everywhere apart from Bahrain, Spain, Hungary, Japan, Brazil, USA. Zandvoort and Saudi unknown.

Ferrari to do a tyre test next week.

 

Monday on slicks, Tuesday and Wednesday on wets.

That's honestly the only reason I see for F1 to keep this convoluted tire-compounds-and-their-obligatory-use system going: To keep people talking about Pirelli.

I think this is a modified SF90 ?

Hope to see a bigger picture later

For now I'm assuming that the Baku accidents were tyre failures. 

Removing downforce, strengthening tyre sidewall, nothing seems to help Pirelli. 

It's like Pirelli is out of its depth in F1.

[Tiakumosan]

Expect increased pressures and maybe an even heavier construction.

[Ivanhoe]

No words 

[DaddyCool]

So after Silverstone last year and now this what's the next step? Pirelli telling Max and Lewis that they shouldn't drive so fast as they are?

 

But again, no biggie, just two guys smashing into the concrete barrier at 300 kph.

[SenorSjon]

Wasn't the Imola puncture last year without warning as well.

"The severity that we measured on telemetry is higher than the simulation," Isola said on Friday. "What we can see is that the teams are stressing the tyres more & we need the real data to judge the real stress, otherwise we have to rely only on the simulation."

[Baddoer]

I have suspision that Pirelli is resonsible for that.

[SenorSjon]

Verstappen ran almost every lap in clean air on those tires, so less heat and less top speed.

[SophieB]

@autosport

Red Bull's Jonathan Wheatley to Michael Masi after Verstappen's tyre failure:

 

"Michael, I know you're busy, but we had zero warning on that tyre. Consider throwing a red flag so everyone can change tyres."

 

#F1 #Formula1 #AzerbaijanGP 

 

 

The zero warning concerns me, as does the heavy crash by Stroll earlier in the race. I’m starting this thread for people to discuss it, plus somewhere to update with any fallout after the inevitable investigations.

[SenorSjon]

Not only that. Verstappen was perhaps one if the few drivers with the hards always in free air and lower top speeds due to lack of tow.

[Muppetmad]

It was unforgivable that the failures happened, and it was unforgivable that Red Bull had to instruct Masi to do his job.

[ARTGP]

Doesn't Paul Ricard have big long straights as well?  They seriously need to get to the bottom of this. This is a new tire construction for this year and it's looking like we will be having the same talks after Paul Ricard and Silverstone.....

Edited by ARTGP, 06 June 2021 - 15:57.

[sportyskells]

I think the next race will have a harder tyre after this one

[Requiem84]

Silverstone in the heat might lead to more of this.

One day the driver in question and won’t get lucky about the moment the tire blows and will get injured or worse.

IIRC both Kvyat and Stroll had relatively lucky escapes from their tyre failures at Silverstone and Mugello last year. Kvyat flew into a concrete barrier at a pretty scary angle and Stroll's car went up in flames after he got out.

[masa90]

Scary stuff. Just complete lottery. Along with how many drivers over the years have called them out on the quality of them and how it affects them.

 

But when they just break randomly, on such highspeeds, even with all the work they put into it...

[ConsiderAndGo]

I’m sure they’ll still be around for years to come.

Always need to make it about themselves, don’t they?

[SophieB]

I forgot we had an existing thread about tyres so I folded my thread about the frightening tyre blowouts today into this one.

[ARTGP]

Should Pirelli just leave? Why do they keep bidding for the F1 contract? It’s time to let someone else do this. Michelin for example (and don’t say Indy ‘05 lol)

[Ellios]

Twitter as an aside:

 

Alexander Rossi on Twitter: "@Ericsson_Marcus @F1 @FirestoneRacing manages to do it. ‍♂" / Twitter

[NewMrMe]

Is  this a different problem to those in the past?

 

Baku is a track where they have always gone for the softest combination of tyre counpounds. It doesn't have any long corners where you would have sustained high lateral g-forces. Barcelona, one such track has been run this year and that has been fine. Other tracks like that typically run the hardest tyre compound selections.

 

What Baku does have is the longest straight of the season. Is it prolonged periods of very high speed running that is the problem here? I am wondering if the circuit we should be worried about is actually therefore Monza.

[Trust]

Exactly this will happen. Expect more lottery races and tyre warming issues.

I've never been a fan of Red Bull, but kudos to them for this,  They saw something that went beyond competition and into safety so did the right thing. 

 

I'm sure in the past other teams have been similarly public spirited, but this time we got to hear it.

[ANF]

I'm going to forego Pirelli's investigation and just leave this here.
(However, they did fill most of it with new tarmac before the cars took to the track on Friday. It's a nice theory though, isn't it?)
 

Is this tarmac or concrete? And is it even flat? Or will it cause left rear punctures?
 

Indeed, quite a lot of kerb removed from the Castle section entry.

 

Yeah I would assume the decision to remove the kerb maybe was made after the driver's briefing of yesterday?
 
This is what it normally looks like.

 

[SophieB]

Lewis Hamilton was potentially at risk of a tyre failure similar to that which put two other drivers out of the Azerbaijan Grand Prix.

 

Max Verstappen and Lance Stroll both crashed out of Sunday’s race at high speed after suffering apparent failures on left-rear tyres. Pirelli’s head of Formula 1 Mario Isola confirmed Hamilton also had a seven centimetre cut on his left-rear tyre.[/size]
 
“Probably in the case of Lewis, the cut was not deep enough to cut the construction, so he was lucky because of all of that,” said Isola. “And in the case of Max and Lance, there was an air loss and therefore a failure.”
Isola confirmed the damage to Hamilton’s tyre was discovered when the race was stopped following Verstappen’s crash.
“We found a cut on the inside shoulder of a rear-left tyre used by Lewis Hamilton in the same stint,” he explained. “The cut was quite deeper and bigger, probably six or seven centimetres, but not cutting the construction. So the tyre was still in one piece.
“When there was the red flag and Lewis came to the pit lane and changed the set of tyres, we have been able to find the cut in the tyre.”

Even it if has, there're like 100km of run off in every direction until there's some wall

Fair play to RB for pushing the red flag. In the end they got reward with Lewis mistake but safety first over results is something to be applauded at. 

 

Pirelli pushed it one step too far with 3 softer compounds this year. Why change a winning formula? Tyres were never a problem last few years here 

[Wolbo]

In both instances it was the C3 tyre that blew up and that compound is always part of the mix.

[ARTGP]

Yeah I don't think it has anything to do with compound. More like engineering failure.  The grip of the actual rubber has nothing to do with the sidewalls blowing out. 

Edited by ARTGP, 06 June 2021 - 18:28.

[Clrnc]

Except that it was the medium tyres last year and the harder tyres team used to one stopping is more durable. Nobody used mediums for one stop last year. 

[PlatenGlass]

Baku is a very dangerous track for this to happen on. The first part of the "straight" is corners so if a tyre had blown out there, they might have done more than just crash along the wall.

[ARTGP]

Except that it was the medium tyres last year and the harder tyres team used to one stopping is more durable. Nobody used mediums for one stop last year. 

 

 

But then why did Pirelli predictions say a 1 stop with 40 laps on the hard was the quickest strategy if they didn't think the hards could actually do 40 laps without exploding.

Absolutely shocking. They need to get to the bottom of this. Whether it was the concrete/tarmac at the entry of the castle complex, some kerb having a sharp edge, or just plain wear over and above anticipated, I’d imagine the drivers aren’t jumping for joy at the prospect of doing another race until the cause of these failures has been clarified.

[Goron3]

Some interesting quotes from Pirelli today about how the loads the cars are putting on them are greater than expected via the simulator.

Must say, I'm very worried about Spa and Silverstone. Even France and Monza.

I can't see a way out of this other than to increase the tyre pressures like Silverstone 2 last year or to enforce two stops.

Yeah that was the mistake and they have to investigate it. But like what Max suspected, they will just blame debris.

Enforcing pitstops would turn the championship into a farce I must say.

Indeed - a failure at Eau Rouge/Raidillon is an unpleasant thought.

Not sure about that. It would at least get drivers pushing more throughout again.

[Spillage]

This is the fourth event I can remember where we've had tyres apparently spontaneously failing at high speed. Something really has to be done, because eventually someone will get hurt when a tyre randomly fails.

It would be bad if this happened once. It would be bad if it wasimited to one season. But four races in four different seasons is unacceptable. Clearly lessons have not been learned.

A pitstop has been mandatory for many a year now, adding another won't make it any more of a farce.
