Sebastian Vettel remains in the dark over the cause of his tyre failure, which occurred in the second of Friday’s practice sessions.
Having been only sixth fastest in the rain affected morning session, Vettel struck back with the quickest time in Free Practice 2, with a best time of 1:49.331, before his session was cut short by a right rear tyre failure as he accelerated up to Blanchimot.
This failure once again raises questions over the safety of Pirelli’s tyre construction, coming just three races after the British Grand Prix, which saw a high number of tyre failures over the course of the weekend.
“We don’t know what happened when I got the puncture in P2”, explained the triple world champion. “We lost the rear right, very suddenly, so we need to have a look – Pirelli is working on finding out why it happened. Other than that, it was a positive day.”
Despite the tyre problem, coupled with a lack of dry running, Vettel remains confident that the work carried out on Friday has put the team in a good position for the rest of the weekend.
“This morning was tricky with a few rain drops and the track was slippery; it’s a lot colder here than Hungary, but that’s Spa and part of this circuit.
“This afternoon, we had stable conditions and both of us seemed happy with what we had.”
The German’s team-mate, Mark Webber, who was just half a tenth down on Vettel in FP2, added that he was encouraged by the split set-up work carried out by the team, which should assist them in finding an optimum balance for the race.
“It’s always tricky here to get the right set up for the whole lap, so we took the opportunity today to try some different ones”, said the Australian. “We’ll go through it tonight.
“We had a pretty good run today but there’s still some performance to find and we need to get the car a bit better balanced in certain conditions. Overall we got good information and it was good to have stable conditions this afternoon.”
