Preview quotes from Pirelli’s Paul Hembery ahead of the German Grand Prix at the Nurburgring this weekend.

Paul Hembery, Pirelli motorsport director

“Surprisingly, the Nurburgring is one of the circuits that we have the least experience of, having only raced there once before in Formula One, but we’re certain that we have chosen the correct compromise between performance and durability by bringing the medium and soft compounds. These were actually the same compounds that we chose for this track in 2011, but since then the tyres have got softer and faster, so we would expect a quicker race time with an average of three pit stops for most drivers. The Nurburgring is not on the whole an especially demanding circuit for tyres but there are still some distinctive aspects to look out for when it comes to tyre management, such as the kerbing on the chicanes. We are expecting a performance gap of 0.8-1.0 second between the two nominated compounds, which should make the strategy options versatile. For this race only, we will bring Kevlar-belted rear tyres, following the incidents at the British Grand Prix. Even though the 2013 high-performance steel-belted version is completely safe when used correctly, the Kevlar-belted version is easier to manage and as long as there is no system in place which allows us to enforce tyre related specifications, like tyre pressures or camber, the incorrect use of which were contributing factors of the tyre failures in Silverstone, we prefer to bring a less sophisticated tyre. From the Hungarian Grand Prix onwards there will be a completely new range of tyres, combining the characteristics of our 2012 tyres with the increased performance of the 2013 specification.”
