That's a marketing twist for you.
Or just say that they have no clue what their tires can do or can't, which I suspect is the reality here.

I can agree that if the tyres are made much thicker and had steel fibres in them that sort of failure would not happen but FOM is the one that asked pirelli to construct the tyre to be that fragile. These tyres are riduclously light weight. And little material or lack of beefiness if you want to call it that, is what you get with light weight tyres. Ferrari are not blameless either. They are not fools they know how thin these tyres are. They should not have run the tyre more than the recommended 25 laps they were told was the limit.
The carcass is part of the tire and it exploded. Or didn't explode?!
I remember some cases of Bridgestones worn to canvas without exploding, that's how you make a high performance high load tire, you make it safe for racing.
Safety first, or that's what the FIA used to claim for ages.

I could have sworn that i read Pirelli stated that the medium tire could last 40 laps at Spa
You may be confusing Pirreli's "optimum race strategy" with some sort of limit, where they tell what they think optimum strategy is before each GP

Here is Ferrari's take from Arrivebene:
“A one-stop race was our plan A. We decided that at 11am, using the data the engineers had collected during the practice sessions. There was a Pirelli engineer standing in our garage and he wasn’t just chewing bubblegum. He would have intervened if the data had shown anything suspicious. Our strategy was aggressive, but not risky.”

So the Pirelli engineer in the Ferrari garage didnt intervene or even question their strategy and i guess he forgot how thin the tires were :o ...cmon Platinum you should know better than that.
Lets not forget Rosberg earlier this weekend who had the same tire let go too here is the top 3 drivers' (IMHO)take from BBC :
BBC reports that no less than three world champions – Lewis Hamilton, Fernando Alonso and Sebastian Vettel – had voiced their concerns about the safety of Pirelli’s tyres in the driver briefing on Friday after Rosberg’s tyre blow-up. The worries were dismissed with the usual excuses of ‘external influence’, which the drivers had to accept, but obviously didn’t believe, as Vettel explained unmistakably.
Spot on.
People are confusing the optimum strategy, at least according to Pirelli, which I'd take with a large pinch of salt, and the tire life expectancy which was stated at 40 laps.
Arrivabenne's quote is pretty damning, Pirelli knew all the way what was Ferrari's plan and they were fine with it, now they deny it. Denying facts is what they are good at, maybe they should open a political counseling office and stop making tires.

My rating for Spa this year is 5. I expected more of the race, but it was average show.

Certainly, a safety issue such as this one should not happen. Moreover, drivers must be allowed to race and push hard. With Pirelli tires, that's not happening. That's what they have been asked to produce? Maybe. But with so many issues historically, one has to wonder - is it always team|driver fault? Isn't it time for a change?
The race was like watching paint dry.
The only thing to talk about is an unsafe Pirelli tire.
Then again Pirelli have been the top topic for many years now as they made racing dull with their bubble gums. Yet they keep sticking to it while they get various WDC and teams lambasting them live on TV. Funny people.

You should definitely watch WWE instead if this race was like watching paint dry.

Awesome overtakes, possible rain increased tension, massive tire blowout on the last lap from a guy who was getting chased down lap by lap and quite a lot of fights up and down the grid.

you dont watch Monaco then i presume because that was nothing in comparison to this race.
People seem to have a very deranged view on F1 races over the years.

Max and Carlos have now both 5 DNF's, and I'm guessing there are a few more coming unfortunatly.

On the evidence of this race, at least some things are clear.
Mercedes PU is miles ahead of the next best PU. Even an under performing Lotus managed to chase down a Ferrari. And Merc haven't used their in season development tokens yet.
Mercedes was more than a second faster in Sector 2 alone compared to a non-mercedes car, without losing a lot of top speed on straights as Nico managed to do good overtakes. Speaks volumes about the chassis.

Close to 2/3rd of the season is over and the gap between Merc and other PUs keeps swelling. On the evidence of these factors, 2016 isn't going to be any different, unless Red Bull manages to strike a deal with Mercedes for the PU. It was amazing to see both the RB drivers' performance all over the circuit, with a PU that is probably the third best and running such a thin rear wing.

Sorry but no, it´s 4 for Max and 5 for Carlos

Carlos DNFs have all of them been due to the car failing, while half of Max DNFs have been because of his own mistakes

Comparing car problems, it´s 2 for Max and 5 for Carlos

Comparing DNFs due to driver mistakes, it´s 2 for Max and 0 for Carlos

Well that is also a way to look at it, I'm not here to argue with you. But a DNF still means Did Not Finish. So both have 5 DNF's. And to correct your "Comparing car problems" should be 3 for Max and 5 for Carlos then. You are right about the misstakes but that was not my point anyway.

Edit:
Lets not get to off topic here.. This is still the Spa race thread..

I feel sorry for Sainz his race was ruined with the start by mechenical problems. And Max had a great race comming from p18 to p8. Taking over on some nice places..

It would have been possible that, the tyres would have gone much before that, had it not for Virtual Safety Car allowing cooling of the tyres. Merhi and Stevens changed their tyres at at lap 15 and they went on for another 28 without any problems. Ericsson and Nasr changed the tyres at lap 9 and 10 respectively and went on for another 34/33 laps!!!
turbof1 wrote:For the record again: A pirelli engineer was right there at Ferrari to atleast object against the strategy. I don't think that has happened.
Is he supposed to? Does he get to see all the details of car's setup and how it affects the tires and then OBJECT? OR Is he just available for consultation only? I believe, because the PIRELLI engineer is an external entity, no team would risk providing all these details and then seek his advice. They probably ask him to provide certain information on tyres that they want and then accommodate in their setups. If anyone had much stronger knowledge of those tyres, it was the team itself based on their practice runs. Unless PIRELLI finds a FOREIGN object affecting the tyre blow out, the responsibility would be on Ferrari for going with an aggressive strategy and setup + the driver for constantly running over kerbs to gain time.
From interviews, I believe with Arrivabene, the Pirelli engineer has access to realtime data. I'm sorry but if you are pressed with your nose into the data, the engineer should have told if it was going to work out or not.

The teams have confidentiality contracts with Pirelli. It is actually the very same way with the FIA: Pirelli gets the data to monitor the tyres, but will never release it to anybody else. The data stream is one way basically, so no risk involved. The responsibility lies with Pirelli, because even they admitted to have weighted the tyre life to 40 laps, which was way off.

Let's also not forget that Pirelli has always denied any responsibility for any issues with tyres, up to and including Silverstone 2013 ("It was not us! It was the teams with their mean opinions on camber and the circuit with their razorblade kerbs! Our tyres are to be truste... Was that Hamilton's tyre exploding over there?").

Also to those claiming that Vettel running over the white curb caused his tire to fail, it failed on the wrong side of the car for that to be the case ;)

The whole point in run-off area is it's meant to be a safe escape route, if you risk your tire exploding going over the run-off it's hardly safe, especially at that particular corner!

All of these excuses are simply excuses, the fact is the tyres are far too fragile!

Eh? It says nothing about the chassis and everything about the Merc PU. Merc could bolt on a tonne of downforce and still outpace the others down the straights...

You only need to look at the ease with which Perez & Grosjean overtook, to see the PU advantage.

In which super market do you get that tonne of downforce? If it is available so cheep, why not other teams with tonnes of cash buying and bolting it on? Yes, the PU allows them to bolt downforce, but you only have look at last year's McLaren to understand the difficulty of managing it with tonnes of peak downforce but thoroughly inconsistent. W06 is finely crafted chassis with great craftsmen adding things that really works and the net result is a dominant car. Great tire life, superior on fuel consumption despite managing to get through all the drag borne out of that downforce and still be fast on straights. Even in the past, Mercedes engines had more power than Renault, but the chassis was not upto scratch and that is where RB were beating.

I don't get this hysteria about the tires. Frankly, I like tires exploding. It makes me sad when it happens to guy I am rooting for and it makes be happy when it happens to the guy I dont like, overall it is fun. It is luck and unpredictable so it makes F1 more interesting. It is like rain or mechanical problems to me, part of the sport. Vettel is crying to much about it. The more predictable F1, the more boring it becomes. I think Vettel and Rosberg are wrong. Poor Pirelli getting bad PR because they did what they are asked to do. I would quit F1 if I were them.

Pirelli were asked to make a tire that fails catastrophically with no warning?

Everyone cares because of safety. If all you want is crashes watch nascar.
