Nico Hulkenberg has no fears of another series of tyre blow-outs after meeting Pirelli

Nico Hulkenberg has renewed confidence in the safety of Pirelli's tyres ahead the German Grand Prix after attending a meeting of F1's Sporting Working Committee at the Nurburgring.

Wednesday's talks were seen as crunchtime when it first emerged that FIA President Jean Todt had requested Pirelli's presence. However, they were pre-empted somewhat by statements both subsequently released. On Monday, the FIA said that it is changing the rule which prevents in-season testing so regular drivers can sample the Hungary tyre at the Young Driver Test held at Silverstone later this month. Furthermore, unanimous agreement from teams will no longer be needed to change the tyre specification once the season has started. The FIA said that this measure would allow it "to take all necessary actions to ensure safety". The tyre to be used in Germany - which was originally developed in response to the delaminations seen in Bahrain and Spain - was to have been introduced at Silverstone but some teams blocked the move as they feared it might lose them competitive advantage. Instead, a modified version of the steel belt design was used that contained a stronger bond with the tread which had previously ripped away. The tyre failed five times anyway, although Pirelli was swift to deny a link between the two. One team who initially vetoed this weekend's tyre were Lotus but their Trackside Operations Director, Alan Permane, said that safety was now paramount. "It's just a Kevlar belt change here. I don't think it will present us any problems whatsoever and if that's improving safety, then of course that's a good thing," he said. Ferrari and Force India were the other teams to object, but Permane said there was now a consensus. "I think there's no doubt," he added. "When it comes to performance, all the teams are there for their own thing; with safety it's a very different matter." Representing the FIA, Charlie Whiting said no teams had voiced concerns that they might lose out because of the changes. "None at all," the Race Director stressed. However, Whiting, who had considered red-flagging the British Grand Prix at one point, added that the thorny subject of teams' mis-use of tyres, which was raised by Pirelli in their own statement issued on Tuesday, was not on the agenda. In the statement, Pirelli blamed the failures on a combination of "rear tyres mounted the wrong way round, low tyres pressures, extreme cambers and high kerbs". "The 2013 tyres do not compromise safety if used in the correct way," the statement pointedly added, although Pirelli Motorsport Director Paul Hembery backtracked rather with a statement of his own shortly afterwards, in which he said he "would like to underline the collaboration and support that we are receiving from the teams". Teams have been switching the rear tyres in the search of performance but the asymmetric structure used so far this year has also placed them under particular strain. As such, swapping the tyres used this weekend - which are asymmetric - will be "strictly forbidden". The Hungary tyre will have a symmetrical structure. In the longer term, Pirelli wants greater power over what teams can and cannot do. But according to Whiting, "that hasn't been discussed at all today. I know there has been some talk about pressures and cambers but that hasn't been discussed with us". He added: "Pirelli are happy because we've come up with what appears to be a good solution. We need to do a little more testing in the Young Driver Test, but that's for Hungary and beyond." It is also understood that Pirelli will be allowed to conduct running either side of the Young Driver Test, at Barcelona and Paul Ricard.
