A far-reaching alteration to the Formula 1 technical regulations for 2022, covering every aspect of the car, prompted another significant change to the tyres. With an imminent move to 18-inch rims after more than 50 years of the 13-inch size, Pirelli's 2022 tyres maintain the same tread width as before, but diameter has increased from 660 millimetres to 720 millimetres. The sidewall height is also reduced to give the tyres a more modern low-profile look.
