Tyre failures unacceptable, says Vettel
FERRARI'S Sebastian Vettel blasted tyre supplier Pirelli after a high-speed Belgian Grand Prix blowout on Sunday that he said could have had grave consequences.
"Things like that are not allowed to happen. Full stop. If it happened 200m earlier, I am not standing here now," the four-time Formula One world champion told BBC television.
The German, who finished 12th, was in third place when the right rear tyre failed on the penultimate lap only moments after he powered through the daunting Eau Rouge sweep at about 300kmh.
Vettel, who was competing in his 150th F1 race, said the drivers need to discuss the situation before Ferrari's home Italian Grand Prix at Monza, the fastest track on the calendar, in two weeks' time.
"It's probably not as bad as it was in Silverstone some years ago but it's not acceptable," he said, referring to tyre failures at the 2013 British Grand Prix that led Pirelli to change the tyres' construction.
Vettel had made only one stop, whereas Pirelli had indicated at least two would be expected, and had done 27 laps on the medium tyres in an aggressive strategy.
"If you look at the images, the actual carcass was still intact. It was a wear issue," said Pirelli motor-sport head Paul Hembery. "If the race had been one lap less, he'd have been on the podium and you'd have said what a genius move.
"Friday was a cut and, in this case, it was wear. The tyre was finished."
Vettel's compatriot Nico Rosberg, driving for champions Mercedes, suffered an explosive failure on Friday that Pirelli concluded was caused by a cut from an external object and not due to structural failure.
Vettel, who later cancelled a scheduled briefing with reporters and left the circuit by helicopter, was clearly not convinced.
"I don't know what else needs to happen," he said. "I think it's a sort of theme that keeps going around, nobody is mentioning but it's unacceptable."
Several drivers, including Vettel, had raised concerns in Friday's briefing with FIA technical head Charlie Whiting, who defended Pirelli.
Asked whether his view had been taken seriously, Vettel replied: "I think it was but what's the answer? Same as every time. There was a cut, debris, maybe something wrong with the bodywork, the driver went off.
"If Nico tells us he didn't go off the track, he didn't go off the track. Why should he lie to us? Same with me. I didn't go off the track. It's just out of the blue, the tyre explodes."
