Kimi Raikkonen's dramatic tyre failure in the closing stages of the British Grand Prix was caused by external damage, Pirelli's investigation has concluded.
Raikkonen was running second when his front-left tyre ripped apart, forcing him to pit with four laps remaining. Ferrari teammate Sebastian Vettel suffered what looked like an identical failure two laps later, though Pirelli immediately stated the two incidents were unrelated.
The investigation into both failures has proven that to be the case, with Vettel's caused by a slow puncture -- something Pirelli revealed last week. By contrast, the tyre manufacturer suggests two impacts with the tyre triggered the problem on the No.
