Lewis Hamilton reckons the German Grand Prix could be one of the hardest in terms of tyre management due to very high temperatures at Hockenheim.
Hamilton posted the fastest time on Friday in the second practice session, a 1 minute 18.341 seconds, which was just enough to put the Briton in front of his Mercedes team-mate, Nico Rosberg – a reversal to how things were at the end of FP1, when Rosberg was fractionally faster.
However, the speed of Daniel Ricciardo in third, will perhaps concern Mercedes more – as the Australian was only a tenth or so slower.
“It didn't feel so bad [today]. It was a pretty good day [overall],” Hamilton told Sky Sports F1
after the session. “But the temperatures are so high [here – 56-58 degrees in FP2] and it is very difficult for the tyres – it is very hard to manage.
“It will probably be one of the hardest races to manage the tyres.”
Asked if he is concerned about the pace of Ricciardo and the Red Bulls and if the loss of the FRIC - Front and Rear Interconnected - suspension systems had allowed them to close up, Hamilton replied: “I guess we will find out tomorrow.
“I couldn't tell you really.”
As for qualifying on Saturday, Hamilton refused to say if he will adopt a different mindset in light of his recent errors in Britain and Austria – both of which left him well down the grid.
“I will tell you after qualifying,” he added.
“Pole is important everywhere you go [though]. You have got a long straight down to turn 6, so there are opportunities created if you are perhaps second. But of course it makes it easier if you are on pole,” concluded the 2008 F1 World Champion.
