Airless wheel technology from Michelin, General Motors

Michelin and General Motors have presented a new generation of airless wheel technology for passenger vehicles — the Michelin Uptis Prototype (or “Unique Puncture proof Tire System”) — at the Movin’On Summit for sustainable mobility.

Michelin and GM also announced a joint research agreement under which the companies intend to validate the Uptis Prototype with the goal of introducing Uptis on passenger models as early as 2024. Michelin and GM are testing the Uptis Prototype, beginning with vehicles like the Chevrolet Bolt EV. Later this year, the companies will initiate real-world testing of Uptis on a test fleet of Bolt EV vehicles in Michigan.

Because Uptis is airless, the breakthrough wheel assembly eliminates the dangerous risk of flat tyres and blowouts:

· Drivers of passenger vehicles feel safer on the road.

· Operators of passenger vehicle fleets minimize downtime and improve efficiency resulting from flat tyres and near-zero levels of maintenance.

· Society at large benefits from extraordinary environmental savings through reduced use of raw materials for replacement tire or spare tire production.

The Uptis Prototype represents a major advancement toward achieving Michelin’s VISION concept, which was presented at the Movin’On Summit in 2017 as an illustration of Michelin’s strategy for research and development in sustainable mobility. The VISION concept introduced four main pillars of innovation: airless, connected, 3D-printed and 100% sustainable (entirely renewable or biosourced materials).
