There is much talk about Pirelli's rain tires, as was also seen in Miami. The 'full wets' were unsatisfactory, with several drivers crashing or missing a turn before the race began. With the data gathered, Pirelli's rain tyres should work better under rainy conditions in 2026.
Racing Bulls to undergo next tests
Following the two days of Mercedes, Pirelli reports that the Racing Bulls will undertake the next test. On 3-4 June, Red Bull's sister team will be in action at the Barcelona circuit in preparation for the following Formula 1 season. Ferrari will perform the next wet tyre test at its own Fiorano circuit on 20 June, using a special rain system to create the right conditions.
