Formula 1’s softest tyre, the C6, will not return in 2026 as Pirelli’s finalised its range of compounds for next season
Pirelli has finalized its range of tyre compounds for the 2026 Formula 1 season, with the softest C6 tyre not making a return.
The decision was made after analyzing data from testing sessions throughout the year, including the last one in Mexico City, to determine the compounds for the new regulations.
In 2026, there will be five dry tyre compounds available, ranging from the hardest C1 to the softest C5.
The C6, introduced earlier in the season to add strategic variation, was not included in the final lineup due to performance differences and the inability to meet the required delta between compounds.
Teams will participate in a one-day test after Abu Dhabi, using sets of C2-C5 compounds and ‘mule’ cars to simulate the expected downforce levels in 2026.
