An extra set of tyres for the teams in the Grand Prize of Australia

The absence of the last test of the season in the Sakhir circuit left Pirelli without the opportunity to test their tires in extremes of temperatures. A problem both for the Italian manufacturer and for the teams that could reach some Grands Prix without too much information on how they will behave gums.
For this reason, the FIA adopted earlier this month a new rule that it allowed Pirelli to deliver a set of tyres extra to each team in some great prizes. This will happen in the first Grand Prix of the year in Australia. Eleven games in each Grand Prize are given to the teams added one extra, that Albert park is the compound "Prime", the hard. In this way Pirelli, will have the opportunity to test the development of new compounds.
That Yes, the extra set of tyres can only be used during the two sessions on Friday. When completion of the free, practice the game must be handed over to the FIA. It will not be the only one that the teams must also submit a game from the main compound and the option.
