Lance Stroll explains tyre-management frustration behind Sepang radio outburst

Stroll said his frustrated radio outburst during the Bahrain Grand Prix in Malaysia was about a tyre-management approach that cost him track position: Aston Martin had expected a demanding stint and managed the tyres accordingly, but they lost temperature and fell out of their window. He thought the Pirellis were more robust than expected and that the race called for flat-out running, not tyre management.

Once Aston Martin started pushing again, overtaking followed: Stroll passed Haas driver Esteban Ocon shortly after the radio message. The earlier tyre management probably cost the team some points, he said.

Stroll finished 12th at Sepang, more than 18 seconds behind race winner Max Verstappen.
