Pirelli, Formula One's sole tyre supplier, has concluded the analysis on Sebastian Vettel's damaged front-left P Zero Yellow soft tyre, which affected him two laps from the finish of the British Grand Prix.
The Ferrari driver was running in a solid third place when his tyre blew and he was forced to return to the pits at a very slow speed, eventually getting the tyre changed and going on to finish the event in 7th place.
As appeared clear since Sunday afternoon, a full investigation has now confirmed that the original cause of the failure was a slow puncture. The consequent driving back to the pits on an underinflated and then flat tyre led to the final failure.
Kimi Raikkonen's damaged tyre shows less evidence of what occurred, so further tests and analysis are still ongoing in Pirelli's laboratories and indoor testing facilities. It will take a few more days to reach a definitive conclusion.
