Pirelli undertook intermediate and wet tyre test of F1 2026 compounds at Fiorano with Ferrari, where they even ran the slick compound.
Day 1 –
Another Pirelli test session dedicated to 2026 tyre development got underway today at the Fiorano circuit. Working with Scuderia Ferrari HP, the Pirelli engineers carried out a comparison of various intermediate and extreme wet prototype tyres, making the most of the artificial irrigation system available at Ferrari’s private track.
Guanyu Zhou was at the wheel of an SF-25, modified to accommodate the dimensions of the 2026 tyres. The Chinese driver completed 159 laps. His best time of all was a 59”820, set on dry weather tyres while preparing for the day’s work. His best time around the 2.976 kilometre track on intermediate tyres was a 1’07”400. Testing continues at this track tomorrow, when Charles Leclerc will be at the wheel.
Day 2 –
The final development test for the 2026 intermediate and wet weather tyres ended today at the Fiorano circuit. The Pirelli engineers were working in collaboration with Scuderia Ferrari HP, continuing their task of comparing various prototypes, in terms of both compound and construction. The tyres were fitted to an SF-25 modified to accommodate the dimensions of the 2026 tyres and the test was run on the artificially watered track, making use of the irrigation system at the Maranello marque’s private test track.
Charles Leclerc was driving today and he completed 110 laps, the best in 59”210, set on slicks, while his quickest lap on intermediates was a 1’06”180. “First of all, I want to thank Ferrari for their hospitality and technical support as well as for the commitment from their drivers,” commented Mario Isola, Pirelli Director of Motorsport. “These two days of testing have been very useful, allowing us to round off the on-track development work for next year’s intermediate and full wet tyres.
“Now we will carefully analyse all the data and finalise the definitive solutions. It’s never easy working on the development of rain tyres, because it’s hard to consistently replicate track conditions and temperature also plays an important part. That’s even more the case this year because the mule cars obviously cannot fully replicate the loads and behaviour expected from the cars built to the new 2026 regulations.
“We had to make the best of the situation and I think we have obtained some interesting results, which, next year, will allow us to provide teams with an improved product, both in terms of performance and the operating window, when compared to the current tyres.” The next test session for 2026 will take place at Silverstone in the week following the British Grand Prix.
