Sustainable mobility calls for sustainable performance
Truly sustainable mobility that benefits everyone and the planet implies, first and foremost, a judicious use of raw materials - especially if they are derived from fossil sources!
Some manufacturers are currently campaigning for the standards to be amended to oblige motorists to replace their tires before they reach the legal wear limit. They argue that, beyond a certain thread depth, tires are no longer as safe to use.
The paradox here is that such a measure would result in an enormous waste of natural resources. However, as far as safety is concerned, no-one could suspect Michelin of overlooking this aspect. It is an interesting issue because it reveals what sets us apart from our competitors.
The correct answer – and there is only one responsible answer here – is that a tire's performance must remain constant until the end of its service life. This is why our research focuses on designing tires in which every last gram of material helps the tire fulfill its role for as long as possible. We want products that are lighter, more robust and longer-lasting.
Everything favor of this approach: not only to save raw materials but also because a tire's energy efficiency actually improves with wear (a tire is 20% more energy efficient at the end of its life). It follows that the longer a tire is used, the less impact it will have on the environment per kilometer traveled!
We (our researchers, engineers and developers) are capable of putting on the market tires that are reliable right up until the limit of the wear indicator. This may not be true of all brands. But the decision is in the customer's hands!
