Silverstone's owners hit back on Monday at suggestions that the circuit's kerbs could be to blame for explosive Pirelli tyre failures on Sunday.
Derek Warwick, President of the British Racing Drivers Club, said he had been out to look at the kerbs and dismissed as "absolute rubbish" reports that sharp edges might have cut the tyre sidewalls.
"These kerbs have been in since 2009. We've had thousands and thousands of cars go over these kerbs and they have been absolutely fine," Warwick, an ex-F1 driver whose brother Paul was killed in a racing accident in 1991, told Sky Sports television.
"We've had them checked by the FIA (International Automobile Federation) and they comply completely," he added as a safety debate raged, with talk of a possible driver boycott of the next race in Germany.
The Briton said the Silversto-ne race — in which strips of tread containing metal belts flew off the tyres and narrowly missed the heads of drivers following behind — had at one stage looked like a disaster in the making.
"We need to make sure it's a good race here at Silverstone in order to bring the crowds back for next year so to say I was panicking would be an under-statement," said Warwick.
