Formula 1's tyre supplier Bridgestone has announced the final final compound allocations of tyres for the last four rounds of the championship.
The Japanese company said it will return to the philosophy of leaving a rubber stiffness gap between the two tyre compounds for the Japanese and Brazilian Grands Prix.
The Super Soft and Soft compounds will be used at the Singapore Grand Prix, while the Soft and the Hard compounds will be taken to Japan.
Super Soft and Medium tyres will be used in Brazil, while the season-ending Abu Dhabi Grand Prix will see the teams using the Soft and Medium compounds.
"We are pleased to release our final allocations," said Bridgestone's Hirohide Hamashima. "Singapore is a street course and based on our experience there last year we feel the soft and super soft is the best choice. For Suzuka we will have a gap in compound hardness.
"This will be an interesting return to this great circuit as half of the circuit has a new surface, so tyre usage considerations could be challenging. In Brazil we also stay with the stiffness gap. It can get very hot in Sao Paulo and we usually see a good race there, although I think we will struggle to have a race as exciting as the one we had last season.
"Abu Dhabi is a new destination for us. Although it is technically a street course, we are bringing harder compounds than we use at the other street courses. We feel that the hard compound would be too stiff for this new circuit, so we are bringing the consecutive soft and medium compounds."
