# Pirelli to Revise F1 Wet Weather Tyres for 2027 Season Drivers demand improvements after struggling with tyre warm-up and grip in Brazil. - **Source:** [The Race](https://www.the-race.com) - **Published:** 2026-11-11 - **Topic:** [sports](https://brifing.si/c/sports) - **Original article:** - **On Brifing:** https://brifing.si/s/e9a46bb5-d150-478a-80cd-c3c11e35f43c ## Drivers Criticize Wet Tyres Formula 1 drivers expressed significant dissatisfaction with Pirelli's current wet-weather and intermediate tyres following the rainy weekend at Interlagos. Carlos Sainz and other competitors highlighted severe difficulties in generating operating temperatures and maintaining rear grip. The feedback suggests that the current rubber fails to provide the confidence required for competitive racing. ## Warm-up Challenges Persist The primary issue identified by drivers like Liam Lawson is the inability to keep tyres within the correct operating window during low-speed laps. Even with less standing water, cars felt nearly undriveable as temperatures dropped rapidly. Drivers fear that these thermal management problems could lead to dangerous situations at colder circuits. ## Design Constraints and Pressures Pirelli's current tyre design is influenced by 2026 rule changes, requiring more robust construction to handle active aero and straight-line forces. Consequently, minimum tyre pressures have increased significantly, rising to 28psi for front intermediates. This added stiffness reduces tyre movement, making it harder for drivers to lean on the rubber. ## Performance Compared to Predecessors Alpine driver Pierre Gasly noted that the current intermediate tyres feel inferior to previous versions, describing the experience as driving on ice. Many drivers feel the tyres lack forgiveness and fail to 'come alive' during a race. This perception of poor grip has prompted calls for immediate development and design revisions. ## Pirelli's Development Path Pirelli motorsport boss Dario Marrafuschi confirmed that a new specification for wet-weather tyres is being finalized for next season. The development team is specifically targeting the warm-up phase of the intermediate tyre to address driver complaints. Final homologation with the FIA is scheduled for December, with more technical details expected then. ## External Factors and Testing Development was hindered by the cancellation of a planned wet test in Bahrain due to geopolitical instability. While other tests occurred throughout the season, the unique demands of different track surfaces remain a concern. Drivers like George Russell emphasized that Interlagos's rough tarmac may have masked deeper issues present at other venues. ## Team Setup and Variability Pirelli suggests that part of the performance disparity lies in team setups, noting that some drivers, like Lewis Hamilton, managed the tyres effectively in Brazil. Marrafuschi believes that as teams gain more experience with the current specifications, they will better understand how to optimize their car configurations for these challenging conditions. ## Future Outlook for 2027 The upcoming 2027 revisions aim to balance the structural requirements of new F1 regulations with the need for better driver feedback. By optimizing the warm-up phase, Pirelli hopes to restore confidence and ensure safer racing in wet conditions. The success of these changes will be critical for maintaining competitive parity across the calendar. ## Sources covering this story - https://www.the-race.com/formula-1/f1-divisive-wet-weather-tyres-to-change-in-2027-what-we-know/ — --- _Summary written by Brifing from the original reporting.
