Spa officials pinpoint cause of tyre failures
24 August 2013 – Race officials at the Belgian Grand Prix believe they have uncovered the root cause of the tyre failures that occurred during Friday practice at the Spa-Francorchamps circuit, having found a piece of heavy metal on the exit kerbs at Turn 13.
Both Sebastian Vettel and Fernando Alonso suffered punctures on Friday close to where the debris was discovered. With Pirelli insisting that the tyre issues were the result of 'outside factors', concerned drivers have now said they will accept the explanation given by the sport’s sole tyre supplier in light of the evidence.
Pedro De La Rosa, Chairman of the Grand Prix Drivers' Association, told BBC Sport he was "very happy" that the cause of the problems had been revealed, adding: "We only asked to know what it was. If it had been the first time we'd seen it, we would have been relaxed but after all the problems this year we were definitely concerned."
The piece of debris is believed to have come from Kimi Räikkönen's Lotus.
