Michelin responds to the disappearance of heating cabins

The new Michelin Pilot Sport Hypercar range WEC 2023 (also used in IMSA), designed exclusively on a simulator, made its debut at the 1000 Miles of Sebring. It offers three rubber specifications (the structure has not changed), all of which respond to a regulatory novelty far from being neutral on performance: the disappearance of tire heating cabins for reasons of energy saving.

The 2023 tires thus have the particularity of rising in temperature much more quickly: Tender cold conditions (temperatures below 15°C or at night), Tender hot conditions (temperatures above 15°C), and Medium hot conditions: track where the tires are stressed, temperatures above 30°C. These tires are available in 29/71-18 (width/outer diameter/inner diameter in inches) front and 34/71-18 rear and are fitted to Cadillac, Ferrari, Glickenhaus, Porsche, Toyota, Vanwall. Peugeot , the only one to use square tires measuring 31/71-18, also benefits from these new rubber compounds.

Conversely, the Rain tire is 100% new (carcass and rubber) and unique. It replaces Wet and Full Wet by being able to meet needs ranging from wet to soggy, through the drying phase. In GTE Am, the range remains the same as in 2022 before the arrival of the GT3 in 2024. In LM P2, Goodyear remains the universal supplier and offers a single specification of slick and rain tires.
