Pirelli expecting answers 'in a few days'
17 July 2017 – Formula 1 tyre supplier Pirelli says it hopes to understand the causes of Kimi Räikkönen and Sebastian Vettel's failures at the British Grand Prix "in a few days".
Räikkönen and Vettel held second and third after the initial pit-stops, where most of the frontrunners moved on to Soft tyres, having started on Super Softs.
However, Mercedes' Valtteri Bottas rose up the order on an alternative Soft/Super Soft strategy, and began to put pressure on them with a sequence of rapid lap times.
Shortly after Bottas cleared Vettel, both Ferrari drivers suffered tyre issues within the space of a couple of minutes, forcing them into the pits for fresh rubber.
Räikkönen dropped to third, while Vettel slipped back to seventh, only narrowly keeping his championship lead over Lewis Hamilton, who recorded a fifth win on home soil.
Pirelli, having stated immediately after the race that the issues were "totally different", hopes to follow up with a more detailed report later this week.
"We started to work immediately after the race, as soon as we had the tyres in the fitting area," said Pirelli's Head of Car Racing, Mario Isola.
"I believe we need to send some of the tyres to Milan to make a better analysis, but obviously we are pushing to have something in a few days."
Expanding on the separate issues, he said: "What we can exclude is that we had any carcass failure on Kimi's tyre, because the tyre was still inflated.
"There is a part of the tyre that is damaged and we will investigate deeply on all the tyres, not only this tyre.
"Sebastian had a different issue, with a loss of air, so we have to understand.
"We will provide a report, and we are working together with the team, because obviously the data from the team is a very important part of the investigation.
"It's in the interests of everybody to understand what happened."
Isola ruled out a risky set-up, stating: "I can say that everybody was within our limits, but I cannot disclose camber or parameters of Ferrari, compared to other teams."
Pirelli had stated pre-race that a two-stop strategy was optimal.
