Jun.14 (GMM) Gerhard Berger has blasted the tyre situation in Formula One, just as Pirelli announced its hands are tied from trying to change it.

Following criticism of its heavily-degrading 2013 tyres, F1's Italian supplier announced on Thursday that, contrary to its desire, the construction of the 2013 tyres will not now be changing.

A statement said one reason is that rain prevented extensive testing of the tweaked design in Canada, but also "that the teams failed to agree unanimously about introducing the changes".

Former Grand Prix winner Berger, who sold his stake in Red Bull's second team Toro Rosso some years ago, was asked if he thinks F1's tyre situation is acceptable.

"No," he answered clearly to Osterreich newspaper.

"I'll say it again -- it cannot be that teams invest millions in wind tunnel tests and engines and then ultimately what decides who is at the front is the tyre manufacturer.

"This is wrong," said Berger.

"I'm for real racing and that the best people are at the front; that the sport, not the tyres, play the main role."
