Michelin develops new fuel-efficient tire for Renault

Filed under: General, Silica, Tires — Notch @ 6:52 pm

Michelin has developed new, highly energy efficient tires to help increase the overall range of Renault’s new model, ZOE. All Renault ZOE models equipped with 15 and 16-inch tires will be fitted with the new Michelin Energy E-V tires.

In its press release, Michelin said its goal in the project was to design tires that help to reduce energy consumption while maintaining safety — especially wet grip — and tread life.

One goal of its design work was reducing heat buildup caused by the deformation that occurs with each rotation of the tire; as the tire’s structure is deformed, the components heat up and some of the energy transmitted by the engine is lost. MICHELIN ENERGY™ E-V tires heat up less while driving, which reduces energy consumption, but the rubber in the contact patch heats up quickly when the brakes are applied, which shortens braking distances.
