F1 tyre suppliers Pirelli have announced that they will bring the compounds below to the fifth, sixth, seventh and eighth rounds of the 2017 FIA Formula One World Championship...
Each driver must save one set of the softest of the three nominated compounds for the Q3 qualifying session. 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.
Each driver must have the two harder sets available for the race and must use at least one of them.
The teams are free to choose the remaining 10 sets (excluding the first five events this year, where Pirelli allocate the sets) thus making up the 13 sets allowed per driver in total for the weekend.
The 2017 tyre compounds nominated so far*:
__ The regulations mean that the tyre sets choice for the long-haul events has to be made by the teams 14 weeks in advance, whereas for the European races the deadline is eight weeks in advance.__*
