MICHELIN ACORUS technology: “it bends but it won’t break”

Our engineers are always working to improve the safety, resistance and performance of our tires. But how can we guarantee their soundness in the most difficult circumstances? For example, how can we ensure they won’t lose pressure when they hit a pot-hole? Our R&D teams focused outside the tire itself to invent the solution: MICHELIN ACORUS technology. The Incubator program saw an opportunity with this invention and through tests and demonstrations with clients and thanks to an innovative partnership, it became an innovation.

On a damaged road surface, the tire-wheel assembly is severely tested, particularly with low-profile tires which are increasingly requested by drivers and car manufacturers.

The MICHELIN ACORUS technology is innovative: two rubber expanders are fitted to a slightly narrower wheel. When the vehicle suffers an impact, the expander extends and safeguards both the tire and the aluminum section of the wheel. Once patented, the principle was then developed in partnership with global tire specialist Maxion Wheels, to create a flexible Maxion wheel equipped with MICHELIN ACORUS technology. The benefits are remarkable. Firstly, and this is the main objective, the wheel and the tire resist impact better and the risks of puncture caused by pinching the tire’s side are reduced, regardless of the vehicle’s speed. Also, because the technology helps avoid punctures, drivers will change their tires less, which will help save raw materials. And finally, it means drivers in countries with damaged roads can use tires with a larger diameter, which improves the look of their vehicle.

With MICHELIN ACORUS technology, we are not reinventing the wheel but we’re definitely improving it!
