The Formula One teams got their first taste of Pirelli\u2019s 2013 tyres during free practice in Brazil, with the Italian firm bringing two extra sets of prototype tyres in addition to the usual allocation of P Zero Silver hard tyres and P Zero White medium tyres that have been nominated for the weekend.<\/p>\n
The teams used the 2013 prototype tyres mainly in the morning session, which were distinguished by orange writing on the sidewalls. The prototype tyres seen in Brazil have a different structure compared to the 2012 tyres, using the current hard compound, but with a quicker warm-up time as well as deliberately faster degradation.<\/p>\n
Daniel Ricciardo (Toro Rosso), Vitaly Petrov (Caterham) and both HRTs were the only drivers to use the prototype tyres at the start of the afternoon session, which got underway in ambient temperatures of 32 degrees centigrade and 46 degrees of track temperature. These unusually warm conditions are not expected to last though: tomorrow should be much cooler for qualifying while there is a 100% chance of rain on Sunday: a hallmark of the already demanding Interlagos circuit, which places a lot of stress on the rear tyres in particular due to its traction loads.<\/p>\n
This gave all the teams \u2013 particularly the two championship protagonists \u2013 an interesting dilemma: whether or not to concentrate on qualifying performance, which will be in held in the dry tomorrow, or to work towards a wet set-up that will be useful for the race.<\/p>\n
All the remaining drivers used the hard tyre at the start of the second session, which was also the only tyre apart from the new prototype used in the first session. Toro Rosso\u2019s Jean-Eric Vergne was the first driver to switch to the medium tyres halfway through the session, followed progressively by the rest of the field, with Lotus driver Romain Grosjean being the first driver to go quickest on them. The fastest time of the day was set by McLaren\u2019s Lewis Hamilton with half an hour to go on the medium tyre: 1m14.026s.<\/p>\n
Hamilton \u2013 who has never led a lap in Brazil despite winning the 2008 title at the Interlagos circuit \u2013 was fastest in the first free practice session in the morning, with a time of 1m14.131s on the orange-marked prototype tyre.<\/p>\n","protected":false},"excerpt":{"rendered":"
