Trulli 'shocked' by Pirellis' behaviour
By Michele Lostia and Matt Beer Monday, March 28th 2011, 09:44 GMT
Jarno Trulli, Lotus, Melbourne 2011Jarno Trulli has criticised the Pirelli tyres again after the Australian Grand Prix, suggesting that the characteristics of the new rubber changed after the final tests.
Predictions of severe tyre wear and drivers needing to pit as many as four times did not come to pass in Melbourne, with Sauber's Sergio Perez even making it through the race with just one tyre change on lap 23 of 58.
But Trulli's Lotus team had issues with tyre warm-up, leaving the Italian frustrated.
"The most important thing to be said is that every result this weekend, whether positive or negative, has a common cause: the Pirelli tyres," Trulli wrote in a column for Repubblica.
"They've left us all shocked. I don't mean they were better or worse than we had expected, I mean that they were completely different: it's as if they have been changed since the last tests in Barcelona.
"During the winter all of us, in every team, have worked with tyres that would deteriorate immediately. It was a characteristic of the tyres, and there's been some polemics too. So we had thought the problem was to make them last long enough.
"Instead here in Melbourne we've found ourselves with tyres that had no durability problems, but in exchange for that they would struggle immensely to get up to temperature."
Trulli reckons Lotus was far from the only team finding it difficult to make the Pirellis work in Australia.
"If the tyres don't get up to temperature it's impossible to get the performance," he said. "During the race only two drivers had no problem getting the tyres up to temperature: [Lewis] Hamilton and [Sebastian] Vettel, second and first.
"Everyone else, some more than others, struggled. Even [Mark] Webber. In my opinion it's the same reason why Ferrari did badly in qualifying."
He added: "Problem is, the cause of this is unknown. You just need a tiny difference in the set-up, in the balance, in the track or air temperature, and even within the same team you get opposite reactions.
"Just think of Vettel and Webber: Sebastian dominated, while Mark at one point would lose two seconds a lap from Alonso. So, this is the real challenge: to understand how to use the tyres. I think it will be one of the key points of the season."
Trulli finished 15th in Melbourne, where Lotus had occupied its 2010 position ahead of Virgin but behind the other midfield teams.

Vamos, que esta sorprendido tanto el como la mayoria de pilotos salvo Vettel y Hamilton de lo diferente que se han comportado los neumaticos en Melbourne respecto de todos los datos y pruebas de pretemporada...
En pretemporada los neumatoicos, incluso independientemente de la temperatura en pista, cogian temperatura rápidamente, o fácilmente y el grado de degradación era muy acusado siendo la vida útil de los neumaticos relativamente corta.. totalemnte opuesto a lo visto en Albert Park, donde pilotos como Alonso o Webber, han tenido problemas para calentar sus neumaticos y la vida util de los mismos ha sido muchisimo más larga... de modo que tan solo dos pilotos (Vettel y hamilton) han logrado poner temperatura en sus neumaticos para clasificacion y sacar asi mejor rendimiento a una vuelta y como todos los demás menor degradacion en carrera...
Se empieza a especular sobre diferentes gomas y compuestos a los utilizados en test de pretemporada por parte de Pirelli, cosa que deberia estar prohibida, puesto que los equipos (entre ellos Ferrari) han basado todos sus estudios y adapatado el coche para tratar de sacar el mejor rendimiento a las especificaciones de neumaticos usadas en pretemporada... de ser esto cierto, es la mayor cacicada y sinvergonceria vista y hecha en mucho tiempo, y eso que se supone Pirelli, favoreceria a Ferrari por ser ambos italianos, y los Ferrari "de calle" calzar neumaticos pirelli...

De la Rosa set for final Pirelli run
By Jonathan Noble Monday, March 28th 2011, 10:59 GMT
Pedro de la RosaPedro de la Rosa has been allowed by McLaren to take part in Pirelli's key private test in Turkey that is scheduled to take place next weekend, AUTOSPORT has learned.
Formula 1's new tyre supplier wants to ensure that its products are well-suited to the intense demands of the Istanbul track - as it eyes evaluation of a new hard compound for this year's race plus further developments for 2012.
And although de la Rosa has recently signed a reserve driver deal with McLaren, Pirelli has made no secret of the fact that it wanted the Spaniard to run one last time at a private test because he has the most knowledge of its preparations.
Speaking to AUTOSPORT about the de la Rosa situation, Pirelli's motorsport director Paul Hembery said: "I've written to the tyre working group advising them that Pedro will be doing that test. I haven't had any negative feedback from them.
"We need to use him actually. He drove the car last year and we have modified the Toyota very heavily - going outside of the current regulations to create much higher downforce. The objective of that is to try and replicate 2010 downforce levels.
"From what I understand the cars here are close to the end of 2010 levels, which is extraordinary, considering the number of changes we have had. So we need him to tell us the differences between the car then and the car now, and we will go through a screening of the current products and work with the new products."
Hembery said that his company had decided to test at Istanbul because the high-speed Turns 8 and 9 were particularly tough on tyres.
"The test is about working primarily for 2012, and we are working on new products too. It is also a check for us for Turkey because Turns 8 and 9 at Istanbul are a big challenge. I am not talking compound but structurally. We want to go there and have a double check to be sure."
