GM and Michelin unveils airless tire prototype

Uptis (Unique Puncture-proof Tire System), an airless Michelin-made tire developed for passenger cars has been unveiled by GM and Michelin. Its a concept tire made to work without the need for inflating it with air. Its made with a mix of composite rubber and resin embedded fiberglass which can sustain highway speeds. Driving at highway speed had been a challenge with earlier versions of the prototype as it only sustained very slow speeds.
Michelin claims it’s just as comfortable as normal air inflated tires though it doesn’t look as good. GM says it will start testing the Uptis in Michigan later in 2019 on a fleet of Chevy Bolts and expects delivery on the finished version in 2024.
Seeing the way the Uptis is designed, it should have very appealing financial and safety benefits right away as it won’t be susceptible to blowouts, flat tires, and irregular wear. GM and Michelin are pitching this as a way to reduces the need for environmentally harmful tire production, and eliminates the need for a spare tire that adds weight and shrinks fuel economy hence playing their part making for a more environmentally sustainable world as electric cars seem to do.
They’d also help autonomous vehicles drive around the clock without fear that a stray nail will ruin a trip.
