The FIA have officially opened up the 'invitations to tender' process in a bid to review the Formula 1 tyre supply for 2025-2027. The governing body will once again be looking a single manufacturer to supply all F1 tyres from 2025 through to 2027, with an option of extending to 2028. Current supplier Pirelli have a contract in place until the end of the 2024 season, and have been the sport's sole supplier since the 2011 season. Any new contract will be for a supply to Formula 1, along with the feeder series Formula 2 and Formula 3, the specifications for which will follow "in the next two weeks". The FIA have stated that the tyre dimensions will be "similar" to the current 18" specification tyres and that an increased emphasis on environmental sustainability will need to be proven across the "complete life cycle" of the tyres by bidding manufacturers. The requirements also stated: "Other technological updates will include the requirement for tyres to be fitted with electronic identification to improve the efficiency of the scrutineering procedures." Despite the "similar" dimensions, the higher-torque power units implemented for 2026 are very likely to require design changes to cope with the revised demands. The estimated torque increase is around 10%. A decision for the new tyre supply contract is expected in mid-June.
