Pirelli has admitted it was left with "little data" after rain disrupted its two-day tyre test at Mugello several times. Both the Ferrari and Haas teams attended to test the 2026 tyre compounds, with the programme focusing on the hardest compounds. Unfortunately, persistent rainfall forced the majority of running onto intermediates and even extreme wets.
“Unfortunately, the weather didn’t help,” commented Mario Isola, Pirelli director of motorsport, in a release following the test days. “That’s a shame, as Mugello is not just a wonderful circuit, but also very demanding on tyres and it would have been useful to get in some consistent running to define the hardest compounds.
