For sustainable society


Michelin and GM have developed a puncture-proof tire

Michelin and General Motors (GM) have presented a prototype of the “Uptis (Unique Puncture-proof Tire System)”, an innovative puncture-proof tire system for passenger cars. These two companies are jointly researching with aiming to introduce Uptis onto passenger vehicles in 2024 and will initiate real-world testing of the Uptis on a Michigan test fleet of Chevrolet Bolt EVs later this year.

Since Uptis is airless, it will eliminate the danger of punctures and improve the safety on the street.  For operators of passenger vehicle, it will minimize breakdown of a car and be almost maintenance-free. And for society, reduced use of raw materials for tires will significantly reduce the impact on the environment. This has been realized due to the ground-breaking evolution of structure and composite materials of tires, which enable Uptis to bear the weight of the car body even at road-going speeds.

The Uptis Prototype is re-designed for today’s passenger vehicles and is also suitable for emerging forms of mobility. In order to maximize their operating capabilities in autonomous, all-electric, shared service or other applications, maintenance-free tires are demanded for future vehicles.

These advancements show common approach by Micheline and GM to provide a safer, more sustainable mobility solutions.
