F1 Monaco GP Strategy Guide: Tyre Options and Pit Stop Windows

Mercedes has made it six poles from six in 2026, but this is the one that truly matters. Kimi Antonelli starts from P1 at a circuit where track position is more vital than anywhere else in the world. However, the teenage sensation's race starts haven't exactly been confidence-inducing so far this season, and lining up alongside him is a highly motivated Max Verstappen, who is desperate to muscle his Red Bull to the front.

Unless the Monaco Grand Prix gets distinctly chaotic---which is always a very real possibility---the cars on the fourth row aren't fighting for a win. But make no mistake, the strategists sitting on the pit wall will heavily dictate the final finishing order.

What Happened in the Past? (2021--2025)

Monaco has a reputation for by-the-numbers, processional races... but that narrative isn't entirely accurate. The last few editions haven't been what you'd call "normal." To gain some insight into what a standard, dry Monaco Grand Prix looks like, we actually have to rewind all the way to 2021.

Last year, Lando Norris won for McLaren in a highly unusual race where a two-pit-stop minimum was mandated by the FIA. It was an interesting strategic experiment, but it has thankfully been abandoned for 2026.

2024 was another oddball event: a massive first-lap red flag triggered a complete restart. Charles Leclerc, who took the original start from pole on the Medium tyre, used the red flag stoppage to bolt on a set of Hards and completed the entire remainder of the race on that single set. Most of the grid followed suit, resulting in a Monaco Grand Prix that featured a grand total of just seven live pit stops. Meanwhile, 2022 and 2023 were completely dictated by wet weather.

And so, we look to 2021. Even this wasn't entirely conventional, with Max Verstappen winning from what was technically P2 (but effectively P1 after polesitter Leclerc suffered a driveshaft failure before the start). Verstappen started on a C5 Soft tyre, out-waited his rivals, pitted on Lap 34 for a C3 Hard, and led every single lap. The top seven cars all executed this exact same strategy, pitting in a tight window between Laps 29 and 35.

What is the Fastest Strategy Today?

In the Principality, track position is king. With tyre degradation traditionally very low, this is a straight up-and-down one-stop race, meaning all three tyre compounds are tactically viable.

Because the best chance to make an overtake is the 300-meter drag race to Turn 1 (Sainte Devote), the Soft tyre---offering the maximum off-the-line grip---is the overwhelming favourite for the race start.

Pirelli's simulations suggest a Soft -> Medium strategy is the fastest route to the checkered flag, with the optimum pit window opening between Laps 31 and 37. However, realistically, that window is highly elastic. Pit stops for the front-runners will likely be opportunistic---triggered by a Safety Car, a Virtual Safety Car (VSC), or a sudden undercut attempt by a rival.

There will be a massive temptation for the leaders to run extremely long, hoping to catch a "cheap" pit stop under a Safety Car. Conversely, there is the ever-present dread that a rival might pull the pin early and gain that exact advantage. Ultimately, the leaders will dictate their stops based on field spread: they will wait until they have built a comfortable 20-second gap to the midfield, ensuring they can pit and re-emerge into clean air.

Are There Alternative Options?

Entering Sunday, all 22 cars have virtually the same tyre allocation remaining: one new set of Hards, one new set of Mediums, and plenty of Softs.

The industry-standard alternative strategy at most circuits is to start on the Hard tyre and go extremely long. In Monaco, the optimum pit window for a Hard -> Soft run sits between Laps 41 and 47. However, the odds of seeing this today are incredibly low. The Hard tyre is sluggish off the line, and giving up positions at the start in Monaco is strategic suicide.

A Medium -> Hard approach has been a winning combination in Australia, China, Japan, and Miami this year. Here, it boasts an optimum window between Laps 33 and 39... but again, it requires sacrificing launch performance at the start.

Far more likely is a Soft -> Hard strategy, which brings the pit window forward to Laps 29--35.

"In the case of a clean race, we clearly expect a one-stop with a Soft and Medium," says Dario Marrafuschi, Pirelli's Head of Motorsport. "The second option, slower by a few seconds, would be Soft -> Hard, and the third option Medium -> Hard... though Medium -> Hard in a standard race is not really the best choice."

...And What If It Isn't a Clean Race?

Everything points to a beautiful, sunny afternoon on the French Riviera, with the chance of rain sitting at a mere 5%. But what else could disrupt the tactical playbook?

The absolute biggest fear occupying the minds of the strategists is the threat of a Red Flag. So far this weekend, we have seen red flags deployed in FP1, FP2, FP3, and Qualifying.

While the primary reason to start on the Soft tyre is launch grip, it also provides crucial flexibility in the event of a Lap 1 stoppage. Because both the Medium and Hard compounds are capable of going the entire distance if bolted on during a red flag, Pirelli suggests the Medium would be the preferred tyre for a restart due to its superior warm-up and grip.

The biggest conundrum would face anyone who takes the original start on a Medium tyre: if a red flag drops on Lap 1, would they dare attempt the remaining 77 laps on a Soft tyre?

"I would not fit the Soft for the longest stint from Lap 2 to the end of the race," warns Marrafuschi. "But also, I would not fit the Medium first!"
