Michelin, GM partner on airless wheel for 2024

Michelin has partnered with General Motors to test the tire company's “airless” wheel technology, which will it says will improve safety and reduce waste by eliminating the possibility of punctures. The two companies expect to begin marketing the Uptis (Unique Punctureproof Tire System) Prototype in 2024.

The novel structure, which has been long in development and is covered by about 50 patents, is made with aluminum, rubber components and resin-impregnated fiberglass, Eric Vinesse, Michelin's executive VP of research and development, explained. Michelin's technology will be tested on a fleet of Bolt EVs beginning this year.
