2020 Formula 1 70th Anniversary Grand Prix - Silverstone, August 7-9

[PlatinumZealot]

Pirelli’s conclude their investigation: https://www.pitpass.com/67554/Pirelli-concludes-initial-investigation-into-Silverstone-tyre-failures

Typical Pirelli hand waving, tand trying to shift blame.....

Combined with the notably increased pace of the 2020 cars (pole position was 1.2 seconds faster compared to 2019) this made the final laps of the Grand Prix especially tough, as a consequence of the biggest forces ever seen on tyres generated by the fastest F1 cars in history.

They don't seem to understand that this is how F1 works, the cars get faster every year.......

To defend Pirelli, they offered the teams a stronger construction for 2020 and the teams refused it even when being made aware of the risks!

Regardless I think there is more the failures than simple wear but alas it is just the initial findings so far. I think it is a political stance to show the teams that they must abide by Pirelli when new tyres are offered!

I don't understand that whole discussion about tyres. Is it too hard to all teams just to do 2 pit stops instead of 1?
For God sake, we want to fly to Mars, while we can't understand that 40 laps for one pack of tyres is too much oO

That’s great in hindsight but when a tyre manufacture says a tyre should do 40 laps you expect it to do 40 laps. You don’t expect it to only manage 38 which includes 4 under the safety car!

Ok, IF Pirelli made a statement that they are 100% sure that hard tyres will last at least 40 laps - that chnages things ^^

But we expect one starship to make it all the way after the first orbital change.

Fortunately for Pirelli and the teams, forecast for Sunday is getting cooler by the day.

We're now down to 21-23C from 25-27C a few days ago!

For each weekend they publish estimates of how long each tire compound should last. At silverstone it was 40 laps for the hards. No car did more than 40 laps, not to mention they has several laps at safety car speeds so they should have lasted even longer.

That’s fine. However we are still in a situation where this weeks Hard is last weeks Medium.......

Pirelli doesn't have a leg to stand on in this regard, as they had no problem with using the 2019 tires this year. At the very least this is another example of them being very poor at ensuring the tires can last the number of laps they quote.

See this I posted yesterday.

In a statement, Pirelli said it had input into the decision and that "several different factors" were taken into account.

Pirelli elaborated: "The teams will no longer have to modify the designs of their 2020 cars, which would otherwise have been necessary to accommodate the different profile of the 2020 tyre construction.

"This will now allow the teams to continue the development of their 2020 cars – which are already at an advanced stage – uninterrupted.

"The use of the 2019 tyres also guarantees the teams stability, with the advantage of using a well-known product during the final season of the current regulations."

The rejected tyres will have been compatible with lower pressures, but sticking with the 2019 spec will likely mean they will have to be upped, as indicated by Pirelli chief Mario Isola in Abu Dhabi.

"If we stay on the current construction the only the only thing we can do, the only tool we have is pressure," Isola said.

"What is on the table is exactly this - we can stay on 2019 [tyres] accepting that pressure is raised according to the performance of the cars, and probably we have more degradation and more overheating."

Estimates... the question is what is the value of acceptable error here. More or less 2 laps or 5 or 8?

Pirelli should be the one handling that. and if they are smart the estimate should always be based on the worst case scenario. In other words if it's 35 to 45 laps they should be telling the teams 35 laps, and if they go over that they are on their own. I do this regularly for my work, because I'm the one that will be held accountable if something goes wrong.

In all honesty, since it's a safety issue Pirelli should be informing the FIA and if limits are not adhered to penalties should be handed out.

You seem to be forgetting that 4 laps were behind the safety car when the tyres were under no strain at all. So it’s not 2 laps but more and removing the SC period gives us 34 laps under racing conditions with an estimate of 40 in Bottas’ case. If Pirelli can’t get it even that close then they are REALLY rubbish at estimating.

Even if they had said 35 laps Bottas was under that in racing conditions anyway (He’d done 34 when they blew).

it would be really cool if they revived the victory wreath for the podium finishers. That would really hammer home the 70th anniversary celebrations. Theyve already handed out the british auto club trophy so it would be strange if they handed it out again

I know, I think Pirelli is always intentionally vague about issues, so they can minimize looking bad. IMO, it shows a major lack of professional integrity! It's a huge safety concern, imagine a front tire letting go like that in the middle of Eau Rouge, or 130R.

Hopefully this weekend they do their job properly!
