Speaking after the race, Pirelli Motorsport Director Paul Hembery refused to give much away before the completion of full analysis, but said the problem was new.

"Obviously today wasn’t foreseen," Hembery explained. "We’ve seen something new. It's a different type of problem. We’re currently performing our analysis."

He added: "We’ve got to go away and understand what happened. When we’ve got the facts then we can understand what’s happened and get to the core of the issue. We take these things seriously and when we have the answers we’ll let you know."

Since they haven't performed a full analysis yet and they are not sure what happened how can they say "it's something new"?

Well since the cutting that occured is a new issue they need to see why and how, cause obv it was a combination of bad sidewall and bad kerb, cause no other kerb has been able to do this ot the sidewalls.

I think this Gary Anderson curb business is just a red herring. Tyres must be safe for all current circuits.

I don't see any teams saying it's too unsafe and wanting to not race in protest,,you know,,,You know like Indy.

Exactly. Unless this particular kerb is indeed new, which I would have thought we would have known by now. Pirelli's job is to provide tires which are safe for all current circuits. They obviously failed to do so. Why should we trust their "full analysis" since they showed they can't do their job properly and they have very good reasons to try and protect their commercial interests? I would have called for an independent investigation on this by FIA or an outside specialist. Did someone have to die yesterday for this matter to be seen as what it is?

Indy 05 was different. We had a tyre war then with teams politicking. If you listen to the drivers you get the Real message.

why didn't this happen during qualifying or trainiing (except the one tire damage) but 5 times in the race?
i think this hints that something happened to the track. maybe a dammaged curb or some parts from a car

Didn't they run the prototype tyres in the training sessions?? In qualifying they didn't run as many laps. It was first afters som 13 laps (was it?) in the race that the first explosion happend.

If the curb was the problem why didn't Porsche Super Cup suffer from the same problems during their race earlier that day.

In practise you do not get the long runs that are comparable to a dry race.

Brundle etc on Sky talked about some kerbs being new and that draining work had been done.

But they long runs on heavy fuel during the practice, isn't it? If the curb was the real issue it should have showed up sometime during the 3 days of running. But no team complained of any cuts on the tires before.

Ironically, two drivers (kimi and Alonso) of the very same teams, who lobbied to prevent the tire changes, were the ones to narrowly escape the impact of the tire debris on their helmets.

Actually FP1 was totally wet with virtually no running and there were considerably less long runs due to the weather this year. Nevertheless there was a tyre failure in FP3 on Saturday.

Well the cuts happend somewhere cause we have seen the pics of the dmged tyres that didnt blow up and there are cuts.

source quoting Anderson report as absolute rubbish
So the BRDC president goes even further to damn Gary Anderson's report. Absolute Rubbish is a hard word but he will know what he is talking about. He has frequently served as FiA "ex driver" steward of F1 meetings. The "cuts" can have happened on normal kerbs if the material of the shoulder was thermally over stressed and failed prematurely on usually non critical stress concentrations from the kerbs.

Supercup run a lot less sidewall and significantly lower G through high speed corners. This doesn't allow excuses from Pirelli, as it's been stated a lot recently, the kerbs have been in since 2009/10 and the cars have ALWAYS hammered that kerb through T4, so it just doesn't make sense that this one year everything goes wrong.

Joe Saward's blog wrote:I think it is fair to say that the mess at Silverstone is a clear result of having tyres that have not been properly track-tested. One hopes that F1 will learn from this and that the powers-that-be will understand that sometimes politics creates dangerous situations. If it is impossible for people to see beyond their own selfish needs, then the sport must find someone to bully them into doing what is necessary. It is a sign of the times that there is no longer anyone with that kind of clout…

Sometimes the "dictatorial style" of Max Mosley was an advantage. Todt just does not think and act that way. Nevertheless I'm sure he has reached a point where he will take the issue by the neck and see it resolved by giving it his personal attention. He is not a quitter and the reputation and authority of the FiA is at stake. He also has the authority to act on safety issues without the consent of the teams and without any delay. Just by reminding them of the obvious he can force a solution that restores the safety of F1 and I'm confident he will do it pretty quickly.

But I spoke to Jean Todt over the weekend and he has said 'Let them test'. So he has allowed them to run two three-day tests between now and...well, when they want, to try and do something for next year, as well as this year, so that's exactly what's going to happen. They can use what they like. No restrictions. None at all, so they can do what they want.

It looks to me like the young driver test is not going to happen and Pirelli will be unlikely to use all the teams. If I would have to make a bet I say they will most likely test with two teams from Red Bull, Ferrari, Lotus or McLaren and not worry about sporting equity too much. On the other hand they could be having most of the data they need from the Barcelona test except the high speed aspect of Silverstone, which could bring their testing requirements down to just one test.
