Busy season start for our engineers – Pirelli concludes wet tyre testing
Concluding the first 2025 test session for its next generation of rain tyres at Circuit Paul Ricard in France, Pirelli comments that it has acquired reams of data essential to its further development work. The focus of this joint testing with the McLaren F1 Team was the wet and intermediate tyres for the 2026 season, when the regulations will stipulate the same 18-inch rim diameter as the current ones, but with a slightly smaller width and external diameter on both the front and rear axles.
