This page is a static snapshot for round 19 (2024 / 2025 Calendar), race date 2024-10-20. The automated sync only refreshes the latest race result, so nominations, strategies and forecast here are edited by hand in app/f1-tyres/data/f1Data.js.

Pirelli slick selection

C2 as Hard, C3 as Medium and C4 as Soft, drawn from the six-compound slick range.

Hard allocationC2 Hard

White Hard

Nominated as the White Hard. Chosen for high resilience against the intense lateral loads through the Turn 3-6 esses and braking into Turn 1 & Turn 12.

Role
Crucial race compound; required for 1-stop or second stint of 2-stop.
Expected stint
24 - 34 laps
Degradation
0.045s / lap
Working range
105°C - 135°C (221°F - 275°F)
Thermal range

Medium allocationC3 Medium

Yellow Medium

Nominated as the Yellow Medium. The baseline compound for the weekend. Expected starting tyre for the top 10 on the grid.

Role
Prime starting tyre offering optimum compromise between launch grip and stint length.
Expected stint
16 - 23 laps
Degradation
0.075s / lap
Working range
100°C - 130°C (212°F - 266°F)

Soft allocationC4 Soft

Red Soft

Nominated as the Red Soft. The mandatory qualifying Q3 tyre. Roughly 0.9s - 1.2s faster than Medium on a single flying lap, but exhibits rapid thermal degradation over long runs.

Role
Qualifying weapon; potential late-race sprint tyre after a Safety Car.
Expected stint
10 - 15 laps
Degradation
0.140s / lap
Working range
90°C - 120°C (194°F - 248°F)

Projected pit stop windows

Three race-distance plans across the 56 laps. Segment widths are proportional to stint length.

Strategy A — Optimal 2-Stop (Recommended by Pirelli)

Pirelli recommended2 pit stopsRisk: Low

Medium ➔ Hard ➔ Hard. Mitigates high tyre degradation in Sector 1 while maintaining strong pace.

  • C3 Medium / Laps 1-18
  • C2 Hard / Laps 19-37
  • C2 Hard / Laps 38-56

Strategy B — Aggressive 2-Stop (Track Position & Undercut)

2 pit stopsRisk: Medium

Medium ➔ Hard ➔ Medium. Gives a fast final charge on fresh Mediums if fuel burns off.

  • C3 Medium / Laps 1-16
  • C2 Hard / Laps 17-38
  • C3 Medium / Laps 39-56

Strategy C — High-Risk 1-Stop (Safety Car Dependent)

1 pit stopRisk: High

Medium ➔ Hard. Requires extreme tyre preservation and vulnerable to severe tyre drop-off.

  • C3 Medium / Laps 1-22
  • C2 Hard / Laps 23-56
