Bridgestone has revealed the compound of tyres that will be used for the final four races on the Formula One calendar.
The first event held under lights on the streets of Singapore will see the Japanese manufacturer utilise its soft and super soft compound rubber while medium and soft compound tyres will be taken to Japan for the second season in succession.
The Chinese Grand Prix will also use the same compound tyres as in 2007, with hard and medium rubber being used although the compounds used in Brazil will change with Bridgestone switching to medium and soft compound as opposed to soft and super soft used last year.
"After eleven races this season we can now confirm our tyre allocations for the final four races of the year," Hirohide Hamashima, director of Bridgestone Motorsport tyre development, said. "This will be the first time for Formula One in Singapore and we will bring the soft and super soft compounds for this interesting new street course. High grip will be required at this track which is the primary reason for our choice.
"In Japan and China we will use the same compounds as we used in 2007. For Brazil we have moved a step harder in our allocation range. This race can be very hot, as we saw last year, and our data from the thrilling final race of last season showed us that this change would be beneficial for the teams."
