Top teams cautious in US GP tyre selections
Formula 1's top teams have decided against an aggressive tyre selection for the United States Grand Prix, as title rivals Mercedes and Ferrari opted for marginally different choices.
Pirelli has made the soft, supersoft and ultrasoft tyres available for the Austin race, which is one step softer than last year.
While Mercedes and Ferrari have chosen seven sets of the ultrasoft tyre for each of their drivers, Ferrari has favoured more of the supersofts.
Kimi Raikkonen and Sebastian Vettel have five and four sets of the red-walled rubber respectively, while Lewis Hamilton has three and Valtteri Bottas four.
That leaves Raikkonen with just one set of softs, while Vettel and Bottas have two sets and championship leader Hamilton three.
Red Bull duo Daniel Ricciardo and Max Verstappen's selections match that of Vettel and Bottas with two sets of softs, four supersofts and seven ultrasofts.
McLaren and Williams have opted for the most sets of ultrasofts with Fernando Alonso, Stoffel Vandoorne, Felipe Massa and Lance Stroll having nine apiece.
