How the tyres behaved during the qualifying:

Medium: Not used during qualifying but might be used in the race as tactics will vary.
Soft: Used by the Mercedes drivers only to get through Q1: could be key to the race.
Supersoft: Around 1.5s faster than the soft on Friday; around 1 sec. gap seen in quali.

Possible race strategies and maximum laps*:
Pirelli recommends that the following numbers of laps are not exceeded on each compound:
Soft = 29 laps
Supersoft = 22 laps

On this basis, the optimal pit-stop strategies predicted by Pirelli are as follows:

QUICKEST
Three-stopper: three stints on supersoft + one stint on soft

SECOND-QUICKEST
Two-stopper: two stints on supersoft + one stint on soft (maximizing the stints on supersoft)

THIRD QUICKEST
Two-stopper: two stints on supersoft + one stint on soft (maximizing the single stint on soft)

SLOWEST
Two-stopper: one stint on supersoft + two stints on soft

Different permutations of compound usage within each strategy are possible.
