Max Verstappen has asked why would Pirelli be changing their rear tyres if, after the Baku blow-outs, they insisted they were safe.
Verstappen lost out on a sure win at the Azerbaijan Grand Prix, the Dutchman leading the race ahead of his team-mate Sergio Perez when his rear left tyre failed.
Pitched into the barrier at high-speed, he was lucky to escape unhurt. So too was Lance Stroll.
Earlier in the race the Aston Martin driver suffered a similar crash, hitting the concrete barrier with force as his rear left also went.
Pirelli investigated the incidents and declared that they were likely caused by how the teams were running the tyres, adamant there was nothing wrong with the rubber.
