Airless tires have been around for a long time on industrial machinery like forklifts and other devices. However, those tires haven’t been available for passenger vehicles until now. Michelin is showing off a new airless tire that relies on rubber “c” shapes underneath the tread in the area where air would normally help the tire maintain pressure. Anyone who’s ever had a flat tire can immediately see the benefit of the Uptis tire; no air means no leaks and no flats.
