Scuderia Ferrari will take part in two days of testing this week at the Circuit Paul-Ricard. This Tuesday, Pirelli will provide the team with a slick prototype for 2025. On Wednesday, the track will be artificially wet if necessary so that the manufacturer tests a new rain tire (with a blue sidewall). Carlos Sainz and Charles Leclerc are expected during this run, with a day at the wheel each.

The wet test is crucial because wet test days are more difficult to organize. Pirelli must in fact reserve the Castellet or the Fiorano route for this, which have artificial watering systems.

The rain tires are the only ones in the Pirelli range that do not require a heated blanket before use. However, they are very unpopular with drivers due to their huge drop in performance compared to intermediates, and are also less used because conditions are rarely extreme on the track. Also, as they evacuate more water than intermediates, they further degrade visibility conditions.

“We have two days of testing. The first is a dry session. The second day we will wet the track”explained Simone Berra, chief engineer of Pirelli, interviewed by Motorsport.com on the objectives of these tests. “We are testing both rain and intermediate tires, but the priority is the rain tire. We would like to improve its performance.”

“We know that currently the rain tire suffers a little too much from overheating and that in terms of performance it degrades quite quickly due to the removal of the covers [chauffantes] that we implemented last year. So we work to reduce tread movement and reduce overheating. We also have a program for intermediates, which involves using new compounds. Our goal is to take the covers off the intermediates, as we did for the wet tires.”

Even if 2025 is the announced target, Pirelli does not rule out introducing the new wet track compounds earlier if the Castellet test is a success. The first day will be no less important as Pirelli wants to freeze the structure of the slick tire for next season and evaluate a range of soft compounds.

“For the slick tire testing on the first day, we mainly focus on freezing the structure for next season”Berra said. “But above all, we will try to also test the C3, C4 and C5 in terms of tire compounds. For the C5, I think it is the first time this season that we are testing it. So it will be interesting to see the results obtained with the new generation compound.”

Before the Emilia Romagna GP, Ferrari had already taken part in a wet track test on behalf of the FIA, as part of the mudguard tests.
