The on-track action at Suzuka is not over yet. Following last Sunday’s Grand Prix, Pirelli will stay in Japan for a two-day testing session alongside Red Bull and Racing Bulls, continuing its development work in preparation for 2027 with an evaluation of new tire constructions and compounds.
Testing schedule and background
Unfortunately, due to conflicts in the Middle East, the initially planned wet test in Bahrain could not take place. That session was meant to use a sophisticated irrigation system to wet the asphalt, providing ideal conditions for evaluating rain tires on a demanding surface, known for its highly abrasive track. The cancellation inevitably affected Pirelli’s planned program of work.
The program was further disrupted by the cancellation of the dry test initially scheduled in Jeddah, also due to conflicts in the region. The absence of both sessions has forced Pirelli to concentrate much of its work during the two-day Suzuka tests, scheduled for Tuesday and Wednesday this week. Red Bull will run on one of the days, while Racing Bulls will take the track on the other.
Using 2026 cars for reliable data
Unlike previous test sessions, this Suzuka program will finally allow the use of the 2026 Formula 1 cars rather than the traditional mule cars. This is a crucial step for Pirelli, as it will provide data that truly reflects the characteristics and performance philosophy of the current regulations. Collecting accurate references is essential for developing the 2027 tire constructions.
With an extremely packed F1 calendar, the opportunities to fully exploit the 40 testing days available per season are limited. Each car on track is considered equivalent to one day of testing. For this reason, many test sessions are organized immediately after race weekends. This approach reduces travel costs and optimizes logistics, as teams are already present at the circuit for the Grand Prix.
Main objectives of the Suzuka test
The primary goal of the Suzuka session is to continue refining the tire construction, which is currently in an advanced phase of development. The tires must ensure a proper response to the high aerodynamic loads that cars experience. These loads are expected to increase significantly as the cars evolve over the next two seasons, as often happens in the early stages of a new technical cycle.
Additionally, the test will provide the opportunity to work on new compounds for the C1, C2, and C3 tires, the three hardest in Pirelli’s range, which were used during last weekend’s Suzuka Grand Prix. Even though the previous race did not show significant issues with graining or degradation, partly thanks to the new asphalt that increased grip levels, Suzuka remains one of the most demanding circuits for tires.
High-speed challenges for tires
The combination of high speeds with the aero activated and the contribution of hybrid power units generates extremely high load values. These forces put the structure and durability of the tires to the test, making Suzuka an ideal location to evaluate both current and future tire performance.
For Pirelli, understanding how the tires respond to these stresses is essential. The data gathered will inform improvements for the 2027 season, ensuring that the tires can handle the increasing aerodynamic demands while maintaining safety, performance, and consistency across different race conditions.
