"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.
