Italian tyre manufacturer Pirelli has claimed that debris was the most likely cause of Sebastian Vettel's tyre puncture at the Abu Dhabi Grand Prix.
The Red Bull driver started from pole yesterday (13th November) and led after the first turn but his right-rear tyre deflated instantly as he moved left for the second turn, causing him to spin-off the track and retire from the race.
Pirelli motorsport director Paul Hembery revealed that a full investigation has been launched into the issue, although he admitted that the cause may never be found.
He said: "We have the tread back, the sidewalls and the rim, so we'll work with Red Bull to find an explanation for Seb. We do know it was an instant deflation at least, and the most likely cause with such a quick deflation is debris.
"You can rule out a number of aspects. It was a used set [of tyres] as well, so from that point of view you can eliminate a whole host of things."
McLaren star Lewis Hamilton secured his third win of the season at the Abu Dhabi Grand Prix, holding off a strong challenge from Ferrari's Fernando Alonso.
