Michelin has released its new e.Primacy All-Season tyre, targeting drivers who want better efficiency across all powertrain types. The new tyre aims to reduce energy consumption while maintaining longevity, with test data showing significant advantages over competing products in both areas.

The Comparison

In treadwear testing conducted on a 2024 Tesla Model 3 using 235/40R19 tyres, the e.Primacy All-Season demonstrated substantial tread life advantages. The tests measured the most-worn groove of a rotated set, with the e.Primacy All-Season lasting 45,764 miles. This significantly outperformed both the Bridgestone Turanza EV at 30,244 miles and the Continental ProContact RX at 32,438 miles. Using the Federal Highway Administration's average annual mileage figure of 13,476 miles per driver, this 13,000-mile advantage could translate to an additional year of service before replacement.

The efficiency gains come from detailed development of the rolling resistance characteristics. ISO 28580 Rolling Resistance Tests showed the e.Primacy All-Season achieving 6.46kg/ton, marking a clear improvement over the Continental ProContact RX T0 at 7.24kg/ton and the Bridgestone Turanza EV at 8.75kg/ton. These laboratory figures translate to tangible real-world benefits across different vehicle types. When fitted to a 2024 BMW M3, the tyres reduced fuel consumption by up to 3.1%. The efficiency gains proved even more significant for electric vehicles - tests on the 2024 Tesla Model 3 RWD showed an increase in battery range of up to 20 miles compared to the tested competitors.

The tyre's performance comes from several technical innovations. At its core, the e.Primacy All-Season uses Michelin's GreenPower Compound, developed to minimize energy loss during normal driving conditions. The construction includes Cushion Guard technology, which places a soft rubber layer between the tread and steel belts. This layer helps absorb impacts and road surface irregularities, contributing to ride comfort. The tread pattern incorporates Piano Acoustic Technology, designed to reduce road noise throughout the tyre's life.

Michelin developed the e.Primacy All-Season as both an original equipment and replacement tyre, making it suitable for electric vehicles, hybrids, and conventional internal combustion engines. The tyre's focus on efficiency makes it particularly relevant for EV manufacturers looking to maximize range figures, while still offering benefits for traditional vehicles through reduced fuel consumption.

The development process included extensive testing across different vehicles and conditions to validate the performance claims. However, Michelin notes that real-world results may vary depending on several factors including driving style, ambient temperature, vehicle settings, and road conditions. This variability particularly affects range and efficiency figures, which can fluctuate based on usage patterns.
