Pirelli: Ferrari tyre issues 'totally different'
16 July 2017 – Pirelli says the tyre issues suffered by Sebastian Vettel and Kimi Räikkönen in the closing stages of the British Grand Prix were "totally different".
Ferrari's drivers suffered failures within the space of a couple of minutes, as most of the field pushed the limit on one-stop strategies, amid Pirelli's two-stop advice.
Räikkönen dropped from second to third, behind Mercedes' Valtteri Bottas, while Vettel fell to seventh, only narrowly holding onto his title lead over winner Lewis Hamilton.
"Two totally different troubles, totally, totally different," explained a Pirelli spokesman, when asked about the failures following the race.
"Both of them very much to the finish of the tyres, which is normal on a track like this after such a race.
"I remind you how much quicker they [the cars] were compared to last year, it was five seconds quicker, which is a huge thing, absolutely the highest gap of all the 10 races gone so far.
"Silverstone is very much working up the tyres, especially the front-left.
"Sebastian got a fail, a puncture, he was very much in the end. From what? We don't know exactly.
"For sure, he flat-spotted when he was fighting with Bottas. Maybe he was fighting sometimes on the kerb, because he was defending a position and so on. But he was simply making his job.
"The difference with Kimi is that when he came to the pits, the tyre was totally inflated, he was not having a total failure to the tyre – it was worn out, of course."
Pirelli is now working closely with Ferrari to determine the exact causes.
"We are analysing deeply the two tyres, because the things are different," the spokesman continued.
"We are fully analysing them together with Ferrari, because we want to go to the very final point, to what originated the failures.
"With Kimi, the tyre is inflated, and you see all the tread worn out, starting to show the cable. With Vettel, you see the tyre worn out, which was broken on the inside, because of a puncture."
Red Bull pitted Max Verstappen for a second time late in the race, amid blistering, the Dutchman's engineer stating: "What happened to Sebastian is exactly why we pitted you".
"Red Bull saw that the performance was finished, exactly as when Vettel said on the radio, 'I have no front-left', because the performance was lost," added the spokesman.
"They stopped again for caution, because they knew that by stopping they were not losing positions, so for them it was much easier [than it was for Ferrari]."
