Ferrari & Mercedes take conservative approach to US GP tyre choice

Mercedes and Ferrari have taken a conservative approach regarding their tyre compound choices for the United States Grand Prix on October 19-21.

Sole supplier Pirelli has nominated the Ultrasoft (Purple), Supersoft (red), Soft (yellow) tyre compounds in order to cope with the demands of the Circuit Of The Americas race track.

Each driver is permitted 13 sets of tyres for each weekend, from which they are permitted free choice of the three nominated compounds for 10 of the sets.

The Mercedes pair of Lewis Hamilton and Valtteri Bottas have each chosen to load up on seven sets of the Ultrasofts and three sets of the Supersoft and Soft compounds.

Ferrari's Kimi Raikkonen has also done the same, however, his team-mate Sebastian Vettel has opted to take one more set of Ultrasofts and one less set of the yellow-marked Soft.

Many of the midfield teams, including Force India, Sauber, Renault and Williams, have opted to take an aggressive approach more than the other teams on the grid by taking more of the purple-marked Ultrasofts.

McLaren has gone the most conservative with Fernando Alonso taking six sets of the yellow-marked soft and Stoffel Vandoorne five sets respectively.
