2021 Azerbaijan Grand Prix - Baku, June 04 - 06

Hahahhaha hilarious.

[Capharol]

they [Pirelli] assuming its the tyre pressure, because the debris excuse is outdated now, so we [Pirelli] start to blame the teams themselves, and because we [Pirelli] cant check it anymore we wash our hands in innocence...

this is so predictable like in a horror move, either the person rans up to the roof or into the basement

Not saying they have done it in this instance, or that no-one else ever has, but Red Bull have been suspected/accused of fiddling with or manipulating tyre pressures in the past, haven’t they, IIRC?

oh come on... this has writen "i blame the others is easier" all over it, and as some users are already in conspiracy mode, i add one to it
[consiparcy -mode-on]
what if Pirelli is just leaking these bit of infos to see how the reaction of the fans to this theory is, if it is acceptable they really blame the teams.[conspiracy-mode-off]

'Red Bull and other teams may not have adhered to tire pressure guidelines'

Research Pirelli

The Italian tire supplier has now started an investigation into the cause behind the blowouts, but does not want to say anything about the course of this. More is expected to be released by the end of next week. However, La Gazetta dello Sport, Italy's largest sports newspaper, already seems to have gained some information. The sports section writes that several teams - including Red Bull Racing and Aston Martin - may not have adhered to the prescribed tire pressure.

Construction error and debris excluded

According to the newspaper, initial investigations have shown that it is not a construction or manufacturing defect. Debris would also be excluded. It is said that Pirelli therefore suspects that a number of teams have not adhered to the recommended tire pressure. The Italian company initially prescribed tire pressures of 20 psi (front) and 19 psi (rear), but later increased this to 20 psi and 22 psi respectively.

Lower tire pressure improves cornering grip, but increases the risk of tire blowouts. Pirelli cannot check the tire pressures of the teams during the race. La Gazetto dello Sport seems to be relying on sources within Pirelli.

Pirelli magic Is on

Not at all. I’m just asking a question. Not accusing anyone of anything. If (any) teams are not running at the specified/allowed pressures then why should Pirelli get hauled over the coals for it?

If they are, then you absolutely do haul Pirelli over the coals, if the tyres can’t survive the amount of laps they specify they will without failing.

I don’t really see the harm in making FP2 90 minutes again or giving the teams one more set of hards if it helps teams with data collection about the hard tyre and avoids dangerous tyre failures that put drivers at risk.

why should they extend the FP2?, when the manufacturer tells you, these tyre last at least 40 laps, why shouldnt you believe them?
Pirelli messed up (wanted to write something else but no good ) they just dont wanna admit it and now looking for other excuses because the "Debris-Excuse" aint working and they know it.

btw: Aston Martin already said they didnt mess with the PSI

[Wouter]

Aston Martin have denied they ran their tyres below minimum starting pressures in Azerbaijan, following a report in Italian media.

According to an unsubstantiated report in Gazzetta dello Sport, an initial investigation by Pirelli has suggested Aston Martin and Red Bull ran their tyres below minimum pressure limits. This report has been denied by Aston Martin.

"We are working with Pirelli to determine the cause of the tyre failure," an Aston Martin spokesperson told RacingNews365.com.

"The team always operates its tyres within the pressure range advised by Pirelli. The tyre pressures were duly checked and approved by Pirelli on the grid in Baku prior to the start of the race."

The sporting regulations require teams to conform with Pirelli's recommended pressures for the start of the race. For Azerbaijan, these rear limits were set at 20 psi, raised from 19 psi on Friday evening after Pirelli witnessed more severe wear than their simulations had predicted.

Pirelli have also confirmed to RacingNews365 that an official statement on the Azerbaijan tyre failures is expected early next week.

This website has also asked Red Bull for a response, but the team was not available for comment.

So red bull and the other teams just have to do the same, and then we know for sure it’s just Pirelli trying to shift blame.

With FP- if you’re so sure Pirelli is lying or can’t be trusted with their estimations, then wouldn’t it only be sensible to think about giving a bit more practice time so the teams can get their own reliable data and not risk having their cars getting wrecked by tyres going pop with no warning? I seem to recall there really isn’t that much running on that compound any more in practice due to the tight schedule. If it prevents what happened to Stroll and Verstappen it surely can only be a good thing.

So now the teams engineered a little blow-off valve in the wheel. Pump the correct psi at the race start, than loose some during the race…

[cooken]

It would be naive to think teams are simply running the spec pressures with no further thought. At the very least they all would have spent time trying to find grey areas to circumvent the specs and effectively reduce pressures.

[dans79]

The teams are running below minimum pressure sounds like BS deflection to me..... If memory serves, A Pirelli or FIA representative is always around monitoring and checking the tires.

Are they allowed to use pressure relief valves for the wheels/tyres? This is something that used to be used in the WRC to control tyre pressure (and wear rate, presumably).

[henry]

The teams spend thousands of dyno and test rig time to life their components. They work within the limits they discover to minimise the chance of DNFs.

For the tyres they can’t perform these tests and so rely on Pirelli to advise on operating limits. In the past there are plenty of examples of teams stretching this advice, running extra camber, lower pressures, even mounting them with the wrong rotation direction.

The FIA now require the teams to adhere to Pirelli’s advice. They enforce this with tests. But we know how teams view tests. The current flex wing issues provide the exemplar. So long as the pressures are OK when tested then what they are when the car is on track is up for grabs.

I’m not saying that’s what happened but we shouldn’t be surprised if it did.

So I’ll sum up what Pirelli is saying: Aston and RB somehow adjusted the tire pressure to their liking during the race, as they went through both pre- and post-race measurements. And the reason for this? To wear out their own tires sooner. Brilliant idea!

[TimW]

Given Pirelli's reputation, if they mandate higher pressures, I think teams will be worried enough to follow that advice. And if not, then a backmarker with little to lose, not a front running team, having the fastest car an no issues switching on the tires.

It’s to give them more grip.
