Pirelli have revealed the tyre compound choices for Brazil and Abu Dhabi, the concluding pair of races on the 2016 F1 calendar.
For the Interlagos round, the Italian manufacturer has opted for the combination of soft, medium and hard compounds for the fifth time this season.
The teams will have to keep a set of mediums and a set of hards for the race, one of which must be used, while the soft is the chosen compound for Q3.
For the twilight season finale in Abu Dhabi, meanwhile, Pirelli have chosen the ultrasoft, supersoft and soft compounds - again, the fifth time such a combination has been used.
