Pirelli says Daniil Kvyat’s British Grand Prix crash was caused by a mechanical problem, not a tyre failure.
After sending the remnants of Kvyat’s tyre back to its base in Milan for study, Pirelli discovered it had failed due to a problem with the tyre bead, which connects the rubber to the wheel. This was caused by another mechanical problem.
“Together with Scuderia AlphaTauri, Pirelli has concluded an investigation into the precise cause of the incident that resulted in Daniil Kvyat hitting the wall during the British Grand Prix on lap 12,” said Pirelli in a statement.
“A separate mechanical issue led to the inside of the right-rear wheel rim overheating, which in turn burned the bead of the tyre. As a result, the bead was no longer able to seal the tyre onto the rim.
“This is what caused the subsequent deflation, with the tyre itself playing no part in the cause of the accident.”
Kvyat said the crash was one of the biggest he has experienced in Formula 1. “That was also good to remind me a Formula 1 car in general when I drive it alone it feels slow,” he said in response to a question from RaceFans. “But when the wall comes at you at that speed you remember that we are actually travelling at a very, very high speed.”
A new tyre barrier has been added at the site of Kvyat’s crash ahead of this weekend’s second race at Silverstone.
