Hot off the back of their new long-term deal with Formula One, Pirelli have announced their choice of tyre compounds for the final four races of the season in the USA, Mexico, Brazil and Abu Dhabi.
This will be the first time since 1992 that the Mexican Grand Prix has been on the Formula One calendar and in that time it has been through a major overhaul.
It has resulted in Pirelli relying solely on data from the simulators on how the tyres will react to the conditions.

The simulators have shown that the most effective tyres around the 4.3km circuit are the soft and medium compounds, but without any physical running on the new surface, Mexico will be a case of learning on the job for the teams and drivers.
Pirelli cannot really afford any more tyre issues for the remainder of the season with various high-profile drivers making their thoughts clear at tracks earlier this season after some dangerous blow-outs.
So many unknowns
With all of this in mind, I fully expect to see plenty of running through the practise sessions in Mexico so the teams can get an understanding of exactly how the tyres are going to react under certain circumstances.
This is the first time I can recall since Pirelli have been back in the sport where there are so many unknowns before we arrive at a Grand Prix. I am intrigued to see how everyone handles it, no doubt whoever finds the best way of using the tyres the quickest will have the upper hand around there.
United States: Soft and medium
Mexico: Soft and medium
Brazil: Soft and medium
Abu Dhabi: Supersoft and soft
