Our C2, C3, and C4 hard, medium and soft nominations this year are roughly equivalent to the 2018 medium, soft and ultrasoft compounds. This should allow drivers to push hard from the start to the finish of each stint. After a very productive test in Barcelona, we feel satisfied that the 2019 tyre range is on course to meet our objectives of combining performance with durability. Of course, there are still a number of aspects – such as degradation over the length of a stint – that will only be revealed after free practice in Australia. One other important consideration in Australia will be seeing how the new aero rules work, and if this leads to more overtaking – which is difficult to establish during testing.
