Description
The Michelin e·Primacy (sometimes including the ACOU designation for Acoustic) is an eco-designed summer or all-season tire engineered specifically for electric vehicles (EVs), hybrids, and low-consumption internal combustion engine vehicles, prioritizing energy efficiency, extended range/fuel savings, and a quiet, comfortable ride.
Key Features and Technology
Exceptional Energy Efficiency: The primary selling point is its ultra-low rolling resistance, which is up to 27% lower than some competitors.
For EVs, this can translate to an extended battery range of up to 7% (approximately 30 extra kilometres on a 400 km range vehicle).
For conventional vehicles, it reduces fuel consumption and CO2 emissions.
Acoustic Comfort: The ACOU (Acoustic) designation often relates to specific noise-reducing technologies, such as Piano Acoustic Technology and Silent Rib Gen 3, which use an optimized tread pattern and a soft rubber layer to absorb road noise and vibrations, making it exceptionally quiet, especially for EVs where road noise is more noticeable.
Safety and Longevity: The tire maintains safety throughout its life. It uses a high-silica compound and U-shaped tread grooves (EverGrip technology) to ensure reliable wet grip performance, even as the tread wears down.
MaxTouch Construction: This design ensures even pressure distribution across the contact patch, which promotes uniform wear and extends the overall lifespan of the tire.
Eco-Designed Components: The tire incorporates energy-saving innovations like the Energy Passive Compound, CoolRunning Sidewalls, and a slim belt, all of which minimize energy loss from heat buildup and flexing.
Performance Profile
Strengths: Best-in-class for efficiency, comfort, and low noise levels. Provides well-balanced handling on dry surfaces.
Compromises: Some reviews indicate slightly longer wet and dry braking distances and reduced corner grip during aggressive wet handling compared to more performance-focused tires, as the design prioritizes efficiency and comfort.
