Pirelli will bring the following three compounds to round 20 of the 2016 Formula One season in Brazil*, to be held (November 10-13) on the Interlagos circuit: 
    P Zero Orange hard 
    P Zero White medium 
    P Zero Yellow soft

These are the tyres that Pirelli has said must be used at some point in the race: 
    One set of P Zero Orange hard 
    One set of P Zero White medium 
Each driver must have both these sets available for the race, and must use at least one of them.

There are the tyres assigned for Q3 in qualifying: 
    One set of P Zero Yellow soft 
Following the regulations, each driver must save for Q3 one set of the softest of the three nominated compounds. This set will be given back to Pirelli after Q3 for those who qualify in the top 10, but the remaining drivers will keep it for the race – as is the case currently.
