Michelin introduces e.Primacy, the French giant’s eco-responsible tire, which boasts the lowest rolling resistance in its category. Available from spring 2021 in 56 sizes, from 15 to 20 inches, the Michelin e.Primacy is the first eco-responsible tire whose full life cycle was taken into account right from the design phase to reduce its environmental impact. "In 1992, Michelin produced the first 'green' tire with low rolling resistance. Since then, what started as a growing awareness has, over the years, become one of Michelin's core convictions," explains Scott Clark, executive vice president, automotive, motorsport, experiences, and Americas Region - a member of the Michelin Group Executive Committee. "The all-sustainable vision that guides the Group's strategy is based on corporate growth balanced between financial and operational performance and guarantees our independence, our long-term impact, our positive contribution to the planet and the attention we pay to people, without whom no result or transformation would be possible”. Michelin e.Primacy earned an "A" rating in energy efficiency and "B" for wet grip. The low rolling resistance translates into a saving of approximately 0.21 litre per 100 kilometres, Michelin says. During the design phase of the Michelin e.Primacy, engineers employed different technologies. Thanks to an innovative compound, the tire sidewalls absorb less energy when flexing, thus reducing fuel consumption and increasing the range of electric vehicles. The U-shaped grooves ensures excellent performance in wet conditions displacing water effectively. Although thinner, the plies offers the same strength as regular ones while requiring less raw material. As a result, they generate less rolling resistance than traditional designs, which helps improve fuel efficiency and reduce vehicle CO2 emissions. The Passive Energy compound, the main reason for Michelin e.Primacy's low rolling resistance, is based on a highly resilient elastomer. Within the compound, the improved elastomer-reinforcement mix reduces energy loss, reducing the amount of fuel or electricity needed to move the vehicle. The Maxtouch structure maximizes the tire's footprint and distributes forces evenly when braking, accelerating or cornering. The Energy AirShield, a highly hermetic belt that reduces energy loss, assisting in reductions in rolling resistance. In terms of eco responsibility, Michelin e.Primacy is the first tire, the company points out, for which the Environmental Product Declaration (Epd) has been published. "Environmental issues are at the heart of our strategic priorities," Clark points out. "In order to reduce our ecological footprint even further, Michelin is committed to reducing CO2 emissions from all its production facilities by 50% by 2030 compared to 2010, with the ultimate goal of achieving carbon footprint neutrality by 2050. A contribution to the achievement of this goal also comes from the Group's commitment to developing solutions to use recycled or renewable materials in manufacturing tires and, at the same time, to the continuous improvement of their performance. By 2030, Michelin tires will be 20% more energy efficient than in 2010."
