Red Bull and McLaren have opted for aggressive tyre selections for the Belgian Grand Prix compared to their rivals, with both opting to take nine sets of the Ultrasoft tyre for each of their drivers.
Red Bull's Daniel Ricciardo, Max Verstappen and McLaren's Stoffel Vandoorne have each elected for the minimum amount of the Soft tyre with just one set apiece and three of the Supersoft tyre.
Fernando Alonso has an extra set of the Soft tyre compared to team-mate Vandoorne.
Mercedes' Lewis Hamilton and Valtteri Bottas have six of the Ultrasoft, whilst Hamilton has four of the Soft, one more than Bottas.
Ferrari have taken a similar selection, but with an extra set of the softest available compound.
