Pirelli has revealed the tyre compounds that it will take to the the next three races in Belgium, Italy and Singapore.
For the Spa and Monza races, the Italian manufacturer will take the medium and the soft compounds, while the Singapore night event will see the return of the soft and super soft combination.
The soft and the super soft were the tyres used in Monaco, Canada and Hungary, while the soft/medium combination has been the most common in recent races like Britain.
"We're learning more and more with every race in our first year of Formula 1, and fine-tuning our compound choices to benefit from the valuable information that we are accumulating," said Pirelli's Paul Hembery.
"We've got three of the most thrilling races on the entire calendar coming up, and we believe that we've arrived at some tyre nominations that are very well-suited to the characteristics of these very different but equally exciting circuits.
"Of course there will always be some unknown factors - such as the weather - but the choices we have made are designed to help teams maximise both their performance and their race strategy."
