Does Pirelli think we are all stupid?

This is a significant point. Watching onboard footage from the WEC shows that they simply couldn't use the kerbs at the top of Raidillon to the same extent as some of the F1 cars were.
Do you think on balance then the trigger was the punishment from the kerbs?be interesting to consider the weights of the cars at the time, as I would expect this to be more problematic earlier on in the race when the cars are still very fat on fuel.
Do we know what the fuel load was like when Rosberg's failed or are we assuming that was cut from debris?
An "exceptional number of cuts" found in tyres used in Belgium

Pirelli investigate their own tyre and find an external factor to be the blame, what a surprise.
Funny how we didn't see tyres letting go regularly 10 years ago.
Apparently there was 30% tread life left on Vettel's tyre.... that seems more than acceptable to me? So I also wonder if the critics will acknowledge that it wasn't Ferrari taking the piss with the strategy that caused this failure.

If you look around 5min 30sec you will see the kerbs are being used and the orange lozenge kerbs were not there.
Nico was on lap 14 of his long run following qually simulation, so on Option rather Prime like Seb.

Well said. Funny how we didn't see tyres letting go regularly 10 years ago.

So if we take it at face value from Pirelli then 2 cars have punctures from kerbs or debris. Not aware of any debris so must be the kerbs then.
So 2 cars rode over the kerbs and suffered cuts to the tyre.
Couple of questions;
What happened to all the other cars that used the kerbs? Why did they not have punctures?
Why did the tread fall off Rosberg's car if it suffered a cut(s), with the 'middle bit' still inflated initially?
Same, to a lesser extent with Vettel's.
I'm confused.
Bet Paul Hembery gets a warm welcome from the Ferrari team and fans at Monza!

They found 62 cuts on tyres used during the weekend at Spa, compared to an average of 1.2 at previous venues. Fortunately all but two did not result in the tyre failing

Problem is, it begs the question, if it was so bad, why did they not make more noise before Sunday?They found 62 cuts on tyres used during the weekend at Spa, compared to an average of 1.2 at previous venues. Fortunately all but two did not result in the tyre failing

Of course you can, but reading something and just accepting whatever you've read without even questioning anything is the easy bit.
Do you also believe Senna forgot how to drive around a corner and died as a result? Do you believe that the 'black box' from his car was so badly damaged that the data could not be accessed? Do you believe that the on-board footage was not captured fully?
I also note Vettel has composed himself at Monza and gone all positive PR (publicly at least) about Pirelli.
It has often been reported that Vettel enjoys a good relationship with Bernie. Maybe one has encouraged the other to be a bit more polite and positive for the 'good of the sport', as it would now reflect badly on the FIA if Vettel remained critical of Pirelli as the FIA say they are also happy with Pirelli's conclusions.
Or you could just repeat what Pirelli say and not question anything you see with your own eyes.
The Pirelli 'findings' are not a surprise are they? They are not really going to conclude that 'our product just fell to bits' are they, even if it did, but it didn't though, did it? No, it didn't, it was full of cuts and the tyre failed because of that, because Pirelli said so.

Ah. Thank you Charlie for revealing your point. You don't actually care you just want a rant about the tyres.
Here is the things though: if you are going down a route of blah blah blah you make a post like yours, subjective, no substance or facts to dispute, just waffle. Pirelli named their evidence and the outcome of their investigation thereby providing everybody with facts to look at/dispute. That's a dumb idea if you are just going to lie!
Pirelli are in a sucky contract of which there is no upside. Quite what the hell they are doing I have no idea but right now I imagine Bridgestone, Firenza, Conti et al are all laughing their tits off. Michelin must need their heads examining to go anywhere near this contract - it's like being an engine supplier to Red Bull!
Tyres should not explode I agree. Managing depredation of tyres within a performance parameter that has many major variables is I presume bloody tricky. Throwing cutting up curbs into that equation is I presume an utterly thankless task that reduces the engineering calculations to utter guesswork.
And the day I believe a driver that says he didn't go off the circuit/make heavy use of the curbs is the day I take up golf!
It's a pissant situation all round.

Isn't it equally feasible that the debris that caused the cuts was crap collecting in the ridges of the curbs. Having seen them sweep circuits they concentrate on the black bit and as far as I am aware don't run the road sweeper machines over the curbs.
Any shards of carbon or metal could easily sit in the curbs and only be an issue when a car disturbs them and or goes far over the curbs. The curbs themselves are supposed to be designed not to cut tyres.

Interesting discussion on tyre pressures and Vettel's failure over on F1 technical - http://www.f1technical.net/forum/viewtopic.php?f=6... .
Seems to suggest that running low pressures increase the risk of sidewall separation, leading to structural failure.
There's also an interesting comment that some of the tyre warmers are extremely hot, hence the 'starting' tyre pressure may be several PSI higher than the 'cold' pressure. The lower limit set by Pirelli/FIA is measured when the tyres are in the warmers....

Watching coverage today, the new (silly) higher pressures they mandated have now been reduced again back within 1Psi of what they were before....
much guessing going on me thinks!
