Horner still uncertain about Pirelli's durability

Red Bull Formula 1 team principal Christian Horner remains skeptical about Pirelli's tyre compounds despite an increase of 2 psi to their pressures.

With both Lance Stroll and Max Verstappen suffering tyre failures at the last round in Baku, there has been an inquest into why the incidents took place with Pirelli saying an increase in 2 psi should prevent similar incidents from taking place. Horner though remains wary.

'We worked fully with Pirelli and the FIA to for them to try and understand what’s gone on because we have worked within the guidelines and prescriptions that Pirelli and so on come up with," Horner told Sky Sports.

"So then you’ve got to ask yourself, why did it happen? So the result is that obviously pressures have been increased. Is 2psi enough to prevent [that] something might happen again? I don’t know.

"We obviously need to rely on Pirelli and their technical expertise. But hopefully, we won’t see incidents like we’ve seen obviously in Azerbaijan."
