Pirelli “disappointed” teams disobeyed tyre advice

2013 Indian Grand Prix

Paul di Resta, Force India, Buddh International Circuit, 2013Pirelli have said they are “disappointed” Lotus, Force India and others did not obey their advice on the maximum stint lengths for each tyre during the Indian Grand Prix.

F1’s official tyre supplier wanted teams to use the soft and medium tyres for no more than 15 and 35 laps respectively.

However some teams exceeded those guidelines by considerable margins during the race. Force India kept Adrian Sutil on his soft tyres for 19 laps, four longer than advised.

Kimi Raikkonen stayed on his medium tyres for 16 laps longer than Pirelli’s recommendation. By the end of his stint his tyres had dropped off badly and he was passed by several cars, forcing him to make an extra pit stop.

Team mate Romain Grosjean ran long stints on both tyre compounds, and achieved the highest finishing position of a driver on a one-stop strategy, rising to third having started on the ninth row of the grid.

“We are disappointed to see that some teams went against our recommendations and used the compounds for longer than we advised them to do,” said Pirelli motorsport director Paul Hembery.

    So Pirelli have been advised to make overall worse tyres so the drivers will be forced to make more pit stops and now some teams have learned to bypass that short coming to make the tyres last longer. Yet Pirelli can’t make even worse tyres because they are already at the brink of melting and it would be a safety concern. I see some new regulations enforced on teams: ‘ it doesn’t matter what you think the tyres would last you will obey our recommendations!’

    I cant believe the majority are calling pirelli “killjoys” ,can you imagine if there had been tyre failures at high speed ,after running them past the recomended stint length. There would be serious legal ramifications,especially if someone was hurt (or worse) .

      Let the teams decide their own tactics…

        @f1mre That’s not really how it works. If the tyres had exploded because teams overused them (like it happened to Perez in Korea) most people would blindly blame Pirelli, as it happened in Korea. Pirelli has to try to make the teams use the tyres as intended to avoid looking bad.

        The same applies to engines, too. You can be sure Renault/Cosworth have a couple of strict guidelines about what their motors can do; blowing motors don’t make good publicity.

    I think the “safety concerns” are a bit of a red herring really.
    Kimi proved that the tyres drop off to beyond useless before they actually fail and fall apart.

    In the end, that’s all it is: advice. The teams can choose to heed that advice or not, but in the end, they’re going to do what’s going to give them the best chance at a good result. If that many teams were able to push the harder tyre beyond Pirelli’s advised limit, then maybe their estimate was wrong.

    So it’s not enough for Pirelli to ruin the race in Silverstone, now they advice how to ruin races.

      You forget the teams were misusing the tyres at Silverstone (and elsewhere), until the regs to prevent this were introduced in Germany.

        I also forget now.
        Were they operating outside of camber or tyre pressure windows?
        I do remember Spa 2011 where RB were arguing with Pirelli over 1/8th degree of camber.

    Build better tyres Pirelli. Your P-Zero’s on vettle RB9 and on my GTi are a load of rubbish. Going back to Michelin when the sidewalls on the current P-zero’s fail and they will

    Pirelli should use two layers of rubber: the good one and a bad one. The good one lats for 15 laps, or however long, and the other layer lasts pretty much forever, but is terrible for racing.

  8. They are saying they are disappointed cos its only a few weeks ago when fans where up in arms when Perez pushed over the limit and blew a tyre. Pirelli can’t win whatever they do or say.

  9. Pirelli have made the 2013 season tedious to watch. 2011 was much more entertaining than this

    Pirelli has insisted that they are ready to leave F1 after this year as they have copped a lot of criticism about their tyres and not enough testing. So I say bring on Michelin.

    Adhering to an advised camber makes sense. This does not. If the tyres are not safe beyond a certain number of laps despite being usable, then they are poorly made.
