Ferrari team radio transcripts of tyre strategy discussions in 2022 Monaco GP

Ferrari team radio transcripts of tyre strategy discussions with Charles Leclerc and Carlos Sainz in the 2022 Formula 1 Monaco Grand Prix.

Charles Leclerc’s radio messages

Before Sergio Perez pitted, Charles Leclerc and his race engineer were already considering a switch directly to slicks:

Marcos Padros	Let me know track condition.
Leclerc	It’s drying up quickly
Marcos Padros	Okay. Copy that. And other drivers thinking about going straight to slicks. Let me know your opinion on that.
Leclerc	Yeah could be a thing but not now.
Marcos Padros	Understood. Sainz lap time 33.0.
Marcos Padros	And if possible, try to use wet patches for tyre temps.
Marcos Padros	Gap to Sainz behind, Sainz lap time 32.6.

However when Charles Leclerc was told Sergio Perez had pitted, he said putting intermediates on could be advantageous. There was no further discussion of slicks from either side before he pitted:

Marcos Padros	So Perez just pitted now, we believe for inters. Confirm inters on Perez.
Leclerc	Inter would be much quicker, for sure.
Marcos Padros	Copy, understood.
Marcos Padros	Gap to Sainz behind 6.3. I will let you know the lap times from Perez.
Marcos Padros	And box this lap, box, pit confirm.
Leclerc	Box this lap.
Marcos Padros	Multi-function tyre position seven, tyre position seven when you can.
Marcos Padros	And box now, box. Verstappen also pitted.
Marcos Padros	Will be tight with Perez.
Marcos Padros	Gap to Perez in front, 4.4.

Carlos Sainz Jnr’s radio messages

Sainz responded to the news of Perez’s pit stop differently, casting doubt on whether the team should fit intermediates:

Adami	For info Safety Car window is open for inters, just in case.
Sainz	Copy.
Adami	Charles lap time 32.0. For info Gasly with inters 31.2 at the back. We are monitoring. Get your plan.
Adami	Hamilton has pitted for inters, for reference, and Perez is three seconds behind.
Adami	And push, in-lap. Perez is in for inters. Push, in-lap.
Sainz	I’m not sure it’s the right call. It’s nearly ready for dry, yeah?
Adami	Okay, copy, we’ll come back to you.
Adami	We would like to cover Checo on our side.
Sainz	I don’t think it’s the right thing to do.
Sainz	In five, six laps, might be dry.

Despite Carlos repeatedly casting doubt on whether they should fit intermediates, the Maranello team initially called him in for a pit stop, then changed their minds. Charles Leclerc came in instead:

Adami	And box, confirm, box. We need to respond to Checo.
Adami	And stay out, stay out.
Sainz	Copy, stay out.

Carlos Sainz made it clear he wanted to stay out until the track was ready for slicks, which he did:

Adami	Charles lap time 31.4.
Adami	Verstappen four seconds behind.
Adami	Charles is coming in for inters. Verstappen 2.8 behind, 2.8.
Sainz	Happy to stay out.
Adami	Okay. Understood.
Sainz	Stay out until dry.
Adami	Copy.
Adami	Checo is in front of Charles. Head down.
Sainz	Who?
Sainz	Checo is in front of Charles with inters. 25.2 lap time.
Sainz	Perez is nine seconds behind, nine seconds.
Adami	Let me know what you think for slicks.
Sainz	It’s going to be a few laps but not a lot.
Sainz	Okay understood. And Mick is on slicks already, for reference, we are monitoring.
