Milan – Pirelli has reported on the performance of the different tire compounds used during the 2021 French Grand Prix, which saw Max Verstappen emerge as winner:
Red Bull’s Max Verstappen won the French Grand Prix thanks to an unusual two-stop strategy, going from P Zero Yellow medium to P Zero White hard to medium again.
Verstappen was the only frontrunner to stop twice today, taking the lead again just a lap before the chequered flag.
Mercedes driver Lewis Hamilton claimed the lead after the first corner but when Verstappen made his second stop, he elected to stay out on a one-stop medium-hard strategy: the tactics used by the majority of the field.
The only other two-stopper was Ferrari’s Charles Leclerc, classified 16th.
Most drivers, including the entire top 10 on the grid, started on the medium tire. Both Aston Martin drivers as well as both Alfa Romeo drivers, plus Alpine’s Esteban Ocon and Haas driver Nikita Mazepin were the only drivers to start on the hard tire, with nobody using the soft during the race.
With the top eight finishers all having started on the medium tire, Aston Martin’s Sebastian Vettel was the highest placed driver to run an alternative starting strategy.
He ran a 37-lap stint opening stint on the hard tire, before switching to the medium and eventually finishing ninth ahead of his team-mate, on the same run plan.
Temperatures were considerably cooler than they had been over the previous couple of days, with rain on Sunday morning that dried out in time for the race but washed the surface clean of residual rubber.
While ambient temperatures remained around 27 degrees centigrade, track temperature was down to about 37 degrees: nearly 15 degrees cooler than free practice and qualifying.
How each tire performed
HARD C2: This was used for a long second stint by the majority of competitors, as well as a very long first stint for Vettel. This compound allowed some drivers to run 37 laps on it, with Hamilton fighting for the win right to the end.
MEDIUM C3: A key element to Verstappen's victory, after Red Bull decided to switch him onto this compound for a two-stopper and final sprint to the flag. McLaren's Lando Norris also used this tire to great effect, pulling a very long first stint before switching to the hard at the end and eventually finishing fifth.
SOFT C4: Not used during the race at all, with the conditions (including today's 'greener' track) favouring the harder compounds rather than the P Zero Red soft, which has a lower resistance to graining.
