Michelin e.Primacy is a “green” passenger summer tire. According to the French tire maker, its key features include strong dry and wet grip, as well as long tread life and extremely low rolling resistance, which raised the bar still higher for other aftermarket tire manufacturers.
When developing the Michelin e.Primacy, the Michelin engineers focused as much as possible on the tire’s environmental performance, and, most likely, it will replace a few tires from the Energy Saver line, even though its visual appearance is very much like that of the Michelin Primacy 4.
It is noted that the Michelin e.Primacy’s rolling resistance is 27% lower than that of other similar summer tires from the world’s top brands, not used anywhere as OEM equipment. Every 100 km of the way, a set of e.Primacy tires reduces fuel consumption by 0.21 l, which after 35,000 km will result in 80-Euro savings.
Due to the CoolRunning innovative design, the sidewalls absorb less energy during deformation, thus reducing energy consumption. A thinner breaker-strip ply requires less raw materials, but this did not compromise the strength of the “green” model. In comparison to standard-construction tires, such an approach made it possible to significantly reduce the e.Primacy’s rolling resistance.
The Energy AirShield technology has improved the air-tightness of the breaker strip, resulting in less energy loss.
The Energy Passive tread compound, based on an extra-supple elastomer, also reduces energy losses and rolling resistance of the Michelin e.Primacy, which, in turn, cuts down the amount of fuel or electricity necessary for keeping the car in motion.
The use of U-shaped grooves as part of the proprietary EverGrip technology, which has already demonstrated its capabilities in the Michelin Primacy 4 model, ensured excellent wet braking performance of the e.Primacy both in a new and in a worn-out condition. Effectively, this means that regardless of the tread depth, the unique profile of the grooves guarantees that water will be dispelled from the contact patch with maximum efficiency.
The MaxTouch technology expands the Michelin e Primacy contact area and evenly distributes the pressure during the braking, acceleration, and maneuvering, which helps to extend tread life.
