Pirelli Formula 1 chief Mario Isola believes lessons can still be learned from the development of the rejected 2020 tyres that will prove useful in forming the compounds for 2021.
Pirelli has cancelled its planned two-day Formula 1 tyre test with McLaren at Interlagos over safety fears after a number of incidents through the Brazilian Grand Prix weekend.
Pirelli will introduce a sixth compound to its Formula 1 range for the 2018 season that is a step below the current ultra-soft tyre, with fans set to select its name via an online vote.
