At a glance
To read an F1 tyre strategy, separate the compound, stint length, pit window and race event. Pirelli’s forecast is a model under expected conditions, not a promise. Monaco 2024 shows how a lap-one red flag can change the plan: every driver except Logan Sargeant changed compound during the interruption, and only seven further pit stops followed for the rest of the race.

Read the tyre label in its event context
Each weekend, Pirelli assigns three slick compounds from its range as Hard, Medium and Soft. The C-number describes a compound family, but “Hard” is relative to that event selection: a C3 nominated as Hard is not automatically the hardest product in Pirelli’s entire range. Wet-weather tyres are separate: the green Intermediate and blue Full Wet serve different surface conditions. A compound name alone does not tell you how long it will last; temperature, circuit surface, car setup, load and driving all matter.
Across the 24 Grands Prix of 2024, Pirelli reported that the C3 accounted for 32.06% of tyre distance, C4 23.47%, C5 16.84%, C2 14.97% and C1 5.56%. These figures cover the season’s slick use mix, not the share of race wins or pit strategies. C3 was selected at every event, which helps explain its broad exposure. The chart is a season-level context; it cannot predict a particular Grand Prix’s preferred compound.

Forecast, then compare with what happened
Before the 2024 Monaco race, Pirelli expected a one-stop strategy, with teams aiming to pit late to reduce time lost and leave room to respond to a Safety Car. The selected slicks were C3 Hard, C4 Medium and C5 Soft. On race day, an opening-lap crash triggered a red flag. Drivers could change tyres during the interruption without a normal pit-lane stop, so all but Sargeant switched to a different compound. Pirelli said Hard and Medium tyres could cover the remaining distance if managed carefully.
The difference between predicted and actual strategy is instructive. The forecast assumed a conventional race in which a driver would make a pit stop to satisfy the dry-race compound requirement. The red flag supplied an interruption where tyre changes were permitted, changing the normal time-cost calculation. Pirelli later recorded seven additional pit stops for the whole race after the interruption. Several were optional tactical stops or fastest-lap attempts; they were not seven mandatory stops.
Stint length is evidence, not a universal life limit
| Observation | Value | How to use it |
|---|---|---|
| Pirelli forecast | One stop, ideally late | Pre-race expectation under ordinary conditions |
| Event slick compounds | C3 Hard / C4 Medium / C5 Soft | Event-specific naming; not a universal C-number mapping |
| Russell longest C4 set | 77 laps · 256.949 km | Observed stint in a low-speed, low-force Monaco race |
| Post-red-flag pit stops | 7 further stops | Pirelli season recap; not the compound switches during red flag |
Pirelli’s season recap lists Russell’s 77-lap, 256.949 km run on C4 at Monaco as the longest distance on that compound. That is a measured example, not a recommended stint length. At Monaco, track position is unusually valuable and overtaking is difficult; cars can manage tyres at a pace that would not be competitive at another circuit. The same tyre can behave differently with higher loads, hotter track temperatures, or traffic.
When comparing strategies, record at least the compound, lap of each stint, stop timing, Safety Car or red-flag interruptions and finishing context. A longer stint may reflect tyre durability, but it can also reflect track position or a deliberate slow pace.

Pirelli’s 2024 season review supplies the 24-GP slick distance shares, Russell’s 77-lap C4 Monaco stint, and seven additional Monaco stops after the red flag. Pirelli’s pre-event strategy was reported in Formula 1’s 2024 Monaco tyre guide. The post-race detail is in F1’s team and Pirelli race comments and the FIA pit-stop summary. The chart uses Pirelli’s stated season percentage values; it is not a stint-success or degradation comparison.
