Vettel and Rosberg were about the have the same issue, but both pitted just in time.

Alonso's reactions to Perez blowout was impressive.

Vergne had by far the scariest one, full pelt down the Hangar Straight, impressed he held it so well.

Yep and I'm sure there was mention on the BBC commentary that Vettels tyres had cuts in them

McLaren chief Martin Whitmarsh has admitted there is a danger that teams will boycott this week's German GP in the wake of the alarming tyre failures which blighted Sunday's British GP.

Four cars suffered blowouts during the grand prix while race victor Nico Rosberg was forced to take a precautionary pit-stop with just ten laps remaining due to damage to his left-rear compound.

The unsettling spectacle - causing severe reputational damage for both tyre supplier and sport - was branded "unacceptable" by Lewis Hamilton after he lost the lead of the race after becoming the first of the quartet to suffer a puncture.

With the next event, the German GP, less than a week away, the drastic possibility of a repeat of the 2005 U.S. GP, when all the Michelin-shod cars withdrew from the event, has already been openly mooted as F1 strives to prevent Sunday's explosive drama turning into a full-scale crisis.

"There is that danger [of a boycott] and rightly so if teams and drivers aren't convinced that they can [race] safely," Whitmarsh acknowledged to Sky Sports News. "But that's not what we want for Formula 1. We have faced some of these issues before at Indianapolis and that was terrible for the sport so we have really got to work together. This is not a time to point fingers, it's time to work together, find a solution and get on with it.

Pirelli have been summoned by FIA President Jean Todt to a meeting of the Sporting Committee on Wednesday and held emergency talks with both Todt and FIA Race Director Charlie Whiting on Sunday night at Silverstone.

Speaking to French television station Canal+, Todt said: "I had a meeting with officials from Pirelli who will obviously investigate all the incidents that occurred in recent days.

"They will come up with proposals for the important meeting with all the teams on Wednesday. From the moment there are safety issues we have to make the right decision, and not just respond emotionally.

"We must analyse things and let the experts come together to meet after that. It will allow us to make a final decision."

It emerged on Sunday night that Whiting considered red-flagging Sunday's grand prix before deploying the Safety Car in order for the circuit to be cleared of debris following the tyre blow-outs on Hamilton's Mercedes, the Ferrari of Felipe Massa and Jean-Eric Vergne's Toro Rosso.

"Four catastrophic failures is a first. It was quite close to being red-flagged," confirmed Whiting. "Quite clearly all that debris was putting people at risk."

Pirelli's investigation into the cause of the tyre failures - the last of which was suffered by McLaren's Sergio Perez after the second Safety Car interruption of the afternoon - was underway even before Rosberg crossed the line to claim his second victory in three races and the tyre makers have already ruled out the production changes introduced for the Silverstone event being a factor in the debacle.

"We can exclude that the new bonding process, which we introduced at this race, is at cause for the tyre failures we have seen today," motorsport chief Paul Hembery declared.

Among the options expected to be discussed at Wednesday's meeting is the immediate reversion to last year's tyres - a proposal already endorsed by Whitmarsh and his Red Bull counterpart, Christian Horner.

Ferrari Team Principal Stefano Domenicali has also suggested that the scheduled Young Driver Test later this month is scrapped in favour of a fully-fledged tyre test, although Whitmarsh has called for a more urgent remedy.

"I think something will have changed by Germany," said the McLaren chief. "I'm not considering that [withdrawing] at the moment, it's something all the teams and drivers will have to take a view on, but we have to support Pirelli and make sure we give them all the information and enough time to make the right decisions."

It will be down to the curbs - watch the video in the link I put on earlie

I know there werent all at turn 4 but if they got damaged on that curb they could fail at any time.

Perez blow put in practice was down to cut tyres.

I think this is nonsense. Ok, the curbs may be a bit on the sharp side but the tires should cope. Plenty of other high-downforce cars from other series have raced at Silverstone this season without exploding after 5 minutes....

Looks like its the teams fault

http://www.pitpass.com/49415-Pirelli-issues-findings-of-its-Silverstone-investigation

After exhaustive analysis of the tyres used at Silverstone, Pirelli has concluded that the causes of the failures were principally down to a combination of the following factors:

1: Rear tyres that were mounted the wrong way round: in other words, the right hand tyre being placed where the left hand one should be and vice versa, on the cars that suffered failures. The tyres supplied this year have an asymmetric structure, which means that they are not designed to be interchangeable. The sidewalls are designed in such a way to deal with specific loads on the internal and external sides of the tyre. So swapping the tyres round has an effect on how they work in certain conditions. In particular, the external part is designed to cope with the very high loads that are generated while cornering at a circuit as demanding as Silverstone, with its rapid left-hand bends and some kerbs that are particularly aggressive.

2: The use of tyre pressures that were excessively low or in any case lower than those indicated by Pirelli. Under-inflating the tyres means that the tyre is subjected to more stressful working conditions.

3: The use of extreme camber angles.

4: Kerbing that was particularly aggressive on fast corners, such as that on turn four at Silverstone, which was the scene of most of the failures. Consequently it was the left-rear tyres that were affected.

The only problems that had come to light before Silverstone were to do with delamination, which was a completely different phenomenon. To stop these delaminations Pirelli found a solution by suggesting that the teams use the tyres that were tried out in Canada from Silverstone onwards. When this proposal was not accepted, Pirelli found another solution through laboratory testing, with a different bonding process to attach the tread to the carcass. So the problem of delamination has nothing at all to do with what was seen in Great Britain.

Following the conclusions of this analysis, Pirelli would like to underline that:

1: Mounting the tyres the wrong way round is a practice that was nonetheless underestimated by everybody: above all Pirelli, which did not forbid this.

2: In the same way, under-inflation of the tyres and extreme camber settings, over which Pirelli has no control, are choices that can be dangerous under certain circumstances. Because of this, Pirelli has asked the FIA for these parameters will be a topic of accurate and future examinations. Pirelli has also asked for compliance with these rules to be checked by a dedicated delegate.

Some pictures I took at Donington. This bike was found with it's rider still sat on it, dead, after he crashed it, so they decided to leave the bike untouched out of respect.

Yep, bet that will now be on a rota with Spa or something.

 

I was watching the European Le Mans Series from the Red Bull Ring this weekend and thought it was better than most tracks on the F1 calendar, as it's got a lot of elevation and a few decent overtaking opportunities. Pretty short lap though.
