Mercedes and Ferrari wrapped up the latest two-day Formula 1 tyre test in association with Pirelli at French Grand Prix venue Paul Ricard on Friday.
Valtteri Bottas completed 112 laps on his second successive day in Mercedes’ W09 while Sebastian Vettel stepped into Ferrari’s SF71H and racked up 121 laps.
It added to the 231 laps completed by Bottas and Charles Leclerc on Thursday, which acted as the 2019 Ferrari driver’s first full day of action in the team’s SF71H.
Pirelli, which has been the championship’s sole tyre supplier since 2011, is permitted 25 days of tyre testing per season, with all 10 teams participating at various points.
Following an initial period for teams to set up their respective packages, Pirelli conducts the run plan and gathers the relevant data, which is then shared between all teams, ensuring no-one gains an advantage.
Teams are not permitted to run upgrades during these test days.
Further tests are planned with Renault in Japan and with Sauber in Mexico after the respective Grands Prix.
The 2019 tyres will be run for the first time by all teams during the traditional post-race test following the season finale in Abu Dhabi.
It was confirmed earlier on Friday that Pirelli will face competition from Hankook regarding the 2020-23 tyre supply, with the Korean company meeting the FIA’s safety and technical standards.
Liberty Media will now decide which party should act as Formula 1’s sole supplier.
