The tires for Singapore and Suzuka are chosen
Pirelli has chosen the range of tires that the teams will use for the next two Grand Prix races that will take place in Singapore and Suzuka, Japan.

The Italian Grand Prix is over, and Formula 1 will begin its Asian tour on the weekend of September 30th. Two races are scheduled: one in Singapore and the second one in Japan. Both Grand Prix will take place over two consecutive weekends, just like the European tour after the three-week break.
For the occasion, two different erasers were chosen for the two Grand Prix:
In Singapore, it will be the C3, C4, and C5 compounds of tires that will be made available to manufacturers and drivers. These are the softest tires from Pirelli.
The last time these tires were used was in Austria. It was Charles Leclerc and Ferrari who emerged victorious, marking their latest win. Is there a small hope for a repeat performance in Singapore?
For Japan, the C1, C2, and C3 tires are chosen for the occasion. They are harder tires than those used in Singapore.
Their last uses were in the Netherlands in front of Verstappen’s public. It was the latter who had won it. These tires had also smiled at Mercedes, who finished 2nd and 4th in the race.
A set of soft tires is still planned for the Q3. This choice is made to keep the medium and hard tires for the race the following day.
