The ultrasoft tyre is the most popular compound choice for the upcoming Austrian Grand Prix, with the majority of teams shunning the soft tyre.
Ferrari have opted for nine sets of the ultrasoft, three of the supersoft and just one of the soft, which is a mandatory race tyre, therefore drivers must have at least one set of the softs in their selection.
Only one other team, Renault, have opted for the same number of the ultrasoft compound as Ferrari.
Mercedes will take eight sets each for their drivers, however Lewis Hamilton and Nico Rosberg differ on their choice of the supersoft and soft, with the latter choosing one less set of the soft in favour of an additional supersoft.
Red Bull's Daniel Ricciardo and Max Verstappen have seven of the ultrasofts, four of the supersoft and two of the soft.
Haas have elected for the least of the ultrasoft at just six.
