MILAN, Italy (Dec. 15, 2016) — Formula 1 racing's move this year to having three tire options per race instead of two meant Pirelli Competizioni had to increase its supply of F1 race tires by 19 percent over 2015.
Pirelli supplied nearly 42,800 tires to F1 teams throughout 2016, but just more than half of them — 22,500 — were actually used, meaning more than 20,000 race tires went unused, according to statistics released this week by Pirelli.
This oddity relates to the nature of F1 racing — because of the sport's knock-out qualifying procedures, the need to supply wet weather tires regardless of weather and cars that didn't finish races meant 47 percent of tires supplied were not used.
Of the 14,604 wet-weather tires supplied, just 1,808 — or 12.4 percent — were used, Pirelli's figures show. All the tires, both those used and unused, were recycled, Pirelli said.
