Photo of Formula 2 car with new 18-inch wheels

The world of Formula 1 is gearing up for the rule and regulation overhaul which is set to hit the sport in 2021. One of those changes will be the increase in wheel size. Formula 2 will be racing with those wheels next year and therefore 18-inch wheels are being tested now in Barcelona. Pirelli shares a photo of the Formula 2 car with its new tires. What do you think?
