LONDON (AP) — Formula One's governing body will allow in-season testing in a bid to address safety fears following several exploding tires at the British Grand Prix.

Jean Todt, the International Automobile Federation president, said in a statement on Monday that the young drivers test scheduled for July 17-19 at Silverstone would now be opened to all F1 drivers, although Mercedes would be excluded after it was reprimanded for holding unsanctioned tire tests in May.

Todt said the unprecedented move — in-season testing was banned over cost concerns — follows Sunday's race where tires exploded on four cars including Lewis Hamilton's and Felipe Massa's. Todt said the incidents "represent a genuine safety concern for the drivers."

Todt also called on tire supplier Pirelli to investigate the problem.
