Tyre Compounds and Strategy

Pirelli provides three dry-weather tyre compounds per race, each offering different trade-offs between grip and durability.

The Details

The Compounds

Pirelli brings three compounds to each race, labeled:

  • Soft (Red) - Maximum grip, shortest life
  • Medium (Yellow) - Balanced performance
  • Hard (White) - Lowest grip, longest life
The actual rubber compounds vary by circuit. What's called "soft" at Monaco might be different from "soft" at Silverstone.

Compound Selection

Pirelli chooses three compounds from their range (C1-C5) based on:

  • Track surface roughness
  • Corner types (high/low speed)
  • Ambient temperatures
  • Historical data
C1 = Hardest, C5 = Softest

Strategic Implications

Teams must use at least two different compounds during a dry race. This creates strategic variety:

  • One-stop strategies often use harder compounds
  • Two-stop strategies can use softer tyres for more pace
  • Track position vs fresh tyres - a constant trade-off

Tyre Allocation

Teams receive 13 sets for a race weekend:

  • 2 sets of hard
  • 3 sets of medium
  • 8 sets of soft
They must return sets throughout the weekend, with only specific sets available for qualifying and the race.

Key Concepts

Compound
The rubber mixture that determines a tyre's grip and durability characteristics.
Degradation
How quickly a tyre loses performance over its stint.
Mandatory Pit Stop
The requirement to use at least two different compounds during a dry race.

Real-World Example

At the 2023 Spanish GP, some teams went aggressive on softs while others preserved their mediums, creating a dramatic final stint where fresher tyres prevailed.
