Pirelli tests new C6 tire ahead of its planned debut in Formula 1 in 2025.

Pirelli is considering expanding the use of soft compound tires in Formula 1 from 2025 due to the increasing number of street circuits in the series. The Italian manufacturer, which recently extended its partnership with F1 until 2027, currently offers six different slick compounds for each race. However, the growing presence of low-grip street circuits has led Pirelli to take action and develop a new tire construction. The recent Monaco Grand Prix received criticism for its lack of overtaking and strategic diversity throughout the race. To address these concerns, Pirelli has been testing an even softer version of its tires at Paul Ricard, with the aim of finalizing their plans for the 2025 allocation. Pirelli Motorsport boss Mario Isola expressed optimism about the progress made, stating that they have promising compounds to reduce overheating and are considering the introduction of a new C6 compound, which would be even softer, to accommodate the increasing number of street circuits on the calendar. Isola clarified that the possible introduction of a sixth compound in 2025 would not be limited to just one race, but rather would be used in several races to improve performance and reduce overheating. The goal is to encourage a mix of one and two-stop strategies, and Pirelli’s proposal includes the homologation of six different compounds next year.
