We’ve cared about sustainability since before standards were imposed on the industry.
As early as 1946, with the introduction of the radial tire (now the most common tire), we reduced the rolling resistance of tires by 30%.
In 1992 we reduced it by another 20% with the addition of the Silica technology.
What is rolling resistance?
Rolling resistance is the main challenge for tire makers since it's intrinsic to the product: an object that rolls creates friction and therefore the engine has to work harder.
The quality of the tire determines the fuel efficiency against that friction force. In 2012, the MICHELIN® ENERGY™ E-V was made available for electric cars to increase their autonomy.
We're currently working on our fifth generation of green tires. We aim to improve fuel economy by at least 2% and also reduced CO2 emissions with each successive generation.
