Bridgestone has announced the tire allocations up until this season's Turkish Grand Prix.
The tire manufacturer announced last month that it would bring the soft and hard compounds to this weekend's Australian Grand Prix, and it has now confirmed the choices for the five races after Melbourne.
The soft and hard options are the choice for Malaysia, China, Spain and Turkey, with the super soft and medium compounds for Monaco.
Bridgestone's head of motorsport tire development, Hirohide Hamashima, said: "Deciding which tires to bring to a grand prix is always a difficult decision, especially as we don't receive advanced notification of the exact weather we will see at the race circuit over the three days of running. Tire performance in Bahrain was good, however, we remain vigilant and safety is the overriding concern for us.
"Shanghai and Barcelona are both quite severe circuits and Istanbul, as we have seen in the past is particularly severe. This is why we are bringing the hardest allocation, while still leaving a gap in our range between the two compounds. For Monaco this year we will have a gap in the allocation, too, which is a change from the two softest compounds which we have brought here previously.
"We have a harder prime compound for Monaco because of the heavier fuel loads and longer stint lengths that the current rules encourage. We believe this allocation should provide a reasonable and interesting difference between prime and option tires for this event."
