Throughout history, there have been 10 tyre suppliers in Formula 1 and Pirelli is one of the longest-running. The “prehistory” of Formula 1 dates back to the first motor racing competitions at the beginning of the 20th century. At that time, almost all cars were open-wheelers, but the first ones really resembling today’s single-seaters did not arrive until the 1920s. Although the early Formula 1 cars raced until World War II, the first Grand Prix valid for the world championship was the one held in 1950 on the legendary Silverstone track in Great Britain. Pirelli was there and was sure to make its presence noted. It equipped the Alfa Romeo of the winner Giuseppe Nino Farina, at the end of the first modern Formula 1 season well before the single-tyre supplier days. Pirelli is the only tyre manufacturer that has competed in Formula 1 with all sizes during the history of the championship, spanning from the tall and narrow tyres with sculpted treads of the 1950s, the 13-inch rims, the slicks, the wide footprint model of 2017 that offered a considerable increase in cornering speeds and set new lap records to the technological revolution in 2022 with the debut of the 18-inch rims. Being the single partner of the championship has allowed Pirelli to gain experience, professionalism and some of the most advanced technologies in the world, which are exploited to develop road tyres made for everyday motoring. Formula 1 has been Pirelli’s most important open-air laboratory for many years now.
