The latest contract, which also covers the supply of F2 and F3, includes an option from the FIA and F1 side for a fourth season in 2028.
The announcement comes just a few days after the FIA had to mandate a maximum of 18-lap stints in the Qatar GP due to tyre issues, as Pirelli identified a microscopic separation in the sidewall between the topping compound and the carcass cords
The tender process began in March, with the two contenders then supplying detailed technical dossiers to the FIA that outlined their plans.
Both companies gained approval from the governing body, and the next stage was to find a commercial agreement with F1.
Bridgestone is known to have made a substantial financial offer, but in the end F1 CEO Stefano Domenicali and Liberty Media decided to stick with the known quantity of Pirelli.
The choice was recently rubber-stamped by the World Motor Sport Council, as reported by Autosport last week.
This time around the process was made more complicated by F2 and F3 being wrapped into a single package, and by the requirement for the contenders to meet tough sustainability targets as F1 heads towards its Net Zero 2030 goal.
As a result from 2024 all Pirelli F1 tyres will be certified by the Forest Stewardship Council.
