Bridgestone announces tyre specifications

Bridgestone Motorsport confirms the tyre specifications for the first five Grands Prix of the 2007 FIA Formula One World Championship which gets underway with the ING Australian Grand Prix at Albert Park on March 18th.

These are drawn from the four dry grooved tyre compounds produced for the season to cover all 17 races. In keeping with Bridgestone's sole tyre supplier status, these compounds are expected to remain constant through the year to enable a level playing field for the teams.

After a change to the Sporting Regulations last week, the two specifications of dry tyre at each grand prix will be visibly distinguishable from one another.

Q&A Kees van de Grint, Bridgestone Motorsport Head of Track Engineering Operations:

Q: How are the compounds for each race decided?

Kees van de Grint: During our winter preparations we had some idea which tyres to use. We then used winter testing, from December until the end of February, to confirm our thoughts. With the Australia spec for example, we changed from what we expected and moved one step softer.

Q: How much of a logistical issue is the late decision to visually differentiate the tyres?

KvdG: It did surprise us a little bit that the decision was made so late but we have always said that we would try to support the FIA's decisions. It does mean more work but it should not be too difficult. It will provide extra information so the media can see and inform the spectators and the public and I think it's of benefit to the sport.
