Pirelli has confirmed that the process of developing the 18-inch tires was concluded.

Why it matters: Formula 1 is set to switch to 18-inch tires from the 2022 season.


  • The wet track session with Alpine’s Daniil Kvyat at Paul Ricard was the final testing event for the new tires.
  • Mario Isola hails virtual modelling as it has helped Pirelli develop the tires during the COVID-19 pandemic.

What he had to say:

  • “Last year, the COVID-19 pandemic meant that we had to revise our test programme entirely, cancelling on-track testing to concentrate on simulation as well as virtual development and modelling.”
  • “This system of virtual screening helped us optimise the number of physical prototypes produced and return to on-track testing for 28 days throughout 2021. We started off the development process with the profile, before moving onto the base construction, and finally homing in on the five compounds that we will homologate for next year.”
  • “The results obtained up to now have been arrived at with the input of the drivers currently competing in the championship, a vital aspect for us, albeit using mule cars.”
