Pirelli investigating cause of Vettel tyre failure 23 August, 2013 75 Sebastian Vettel’s Red Bull suffered a tyre failure in FP2 Pirelli inadvertently returned to the Formula 1 spotlight on Friday, when Sebastian Vettel suffered a puncture during Friday practice at the high-speed Spa-Francorchamps circuit. The incident had many paddock dwellers recalling the tyre-exploding chaos of Silverstone earlier this year, but Red Bull’s Vettel did not immediately point a finger. “Pirelli is working on finding out why it happened,” he said. Simon Cass, the correspondent for the Daily Mail newspaper, said the early suspicion is that debris – rather than a fundamental tyre problem – caused the problem. Red Bull team boss Christian Horner is quoted by Auto Motor und Sport: “Since Sebastian brought the tyre back to the pits in basically one piece, the chances are good that Pirelli can find the cause relatively quickly.” (GMM) Subbed by AJN.
