On a race weekend, drivers have to hand two sets of slick tires back to Pirelli following each practice session. This leaves each team with seven sets of tires per driver for the race itself.

Michelin brings symmetrical front tires and asymmetrical rear tires with a reinforced right side to handle COTA's specific demands.

While other rookies and teams struggled in rainy Melbourne, Mercedes and their youngster emerged tied atop the standings.
