With just over three weeks to go before the 2009 Grand Prix season kicks off in Melbourne, the new slick tyres are getting a lot of attention.
And in the latest twist, FIA confirmed they have asked Bridgestone to change the tyres for 2010 after admitting they made a ‘mistake’ with the tyres dimensions.
Bridgestone’s tyres for the 2010 season will feature a bigger difference between the widths of the fronts and rears. Some teams at Jerez this week have been testing proposed changes to the Japanese supplier’s products for next year.
It is said that, due to the reintroduction of slicks this year at the same time as radical changes to the aerodynamic regulations – as well as the introduction of KERS – the dimensions of the 2009-specification tyres are producing more than expected levels of rear wear.
The FIA has reportedly asked Bridgestone to change the ratio of tyre width for its 2010 tyres, either by widening the rears, or supplying a narrower front tyre.
“We have to admit that we made a mistake,” FIA President Max Mosley told Auto Motor und Sport. “We should have anticipated that the rear tyres would be a weak point.”
The result, in 2009, is that by producing a better car balance by moving the weight distribution overly forwards, the benefit of the Kinetic Energy Recovery Systems is effectively negated.
“We will ask Bridgestone to change the tyre dimensions for 2010,” Mosley confirmed.
