Why does F1 only use Pirelli tyres? Agreement between two companies explored

Pirelli has been the exclusive supplier of tires for F1 since 2011. It entered the sport after Japanese tire manufacturer Bridgestone's departure, with the company being the sole supplier since 2007.

Before 2007, the sport had multiple companies supplying tires. In fact, back in the 1950s, the sport had up to a whopping five manufacturers. That was until the FIA decided that high levels of competition and prices led to swiftly rising costs and large gaps in performance between teams. As a result, it was decided that a single company would be in agreement to supply tires in F1.

Pirelli is on contract to remain as a supplier for the sport until the end of the 2024 season after being granted an extra year following a delay in the FIA's introduction of the new technical regulations. The 18-inch rubber tires were introduced in 2022 rather than as initially planned in 2021 after the COVID-19 pandemic hit.
