Unlike the other Word Endurance Championship rounds, where teams are limited to two types of slicks, the regulations for Le Mans 24 Hours allow the use of all the three types of slick compounds.
The Hypercar teams can chose between three types of slicks (Soft, Medium, Hard).
- Soft: temperatures below 15°C, or night-time racing.
- Medium: temperatures above 15°C.
- Hard: temperatures above 30°C.
- A versatile WET option is also available for conditions ranging from damp to very wet.
Hypercars are the headlining class for the sport's most powerful prototypes (around 1,000hp). The category includes the LMH (Le Mans Hypercar) cars run by Toyota, Peugeot, Ferrari, Glickenhaus and Vanwall), plus the LMDh (Le Mans Daytona hybrid) prototypes fielded by Porsche and Cadillac.
The LMGTE AM cars can choose between three different types of slick and two wet-weather tyres.
- Soft: temperatures below 20°C, or night-time racing, for example.
- Medium: temperatures between 15°C and 35°C.
- Hard: temperatures above 30°C.
- Rain tyres: Michelin's Drying Wets (for drying conditions) and Full Wets (heavier rain) have identical tread patterns.
For the centenary Le Mans 24 Hours, Michelin's tyres will have a coloured marking on their sidewalls to facilitate the identification of which car is running which type of tyre at any given moment.
Michelin has been nominated by the FIA (Fédération Internationale de l'Automobile) and ACO as the sole tyre supplier to the Hypercar prototypes. The LMGTE Am regulations permit open competition between tyre brands, but all the competitors have chosen to race on Michelin tyres since 2018.
