Puncture-Proof Tires Revealed By GM and Michelin

At an event in Montreal earlier this week, Michelin and General Motors unveiled a new airless wheel prototype called the Uptis Prototype, which stands for "Unique Puncture-proof Tire System." The prototype looks like an old-fashioned tire, but has treads in the middle and no sidewalls. Interesting Engineering reports: "Uptis" as it is more simply called, was first unveiled at the Movin'On Summit for sustainable mobility in 2017. The aim is for a complete reshuffle of conventional wheels and tires, so that they are fully replaced as an assembly unit for passenger cars. GM's plan is to start tests at the end of this year on their Michigan-based Bolt Electic Vehicles (EVs). The airless tire has all-round benefits: less raw material and energy are used in their production, the amount of scrapped tires due to punctures or damage will dramatically minimize, wear and tear issues due to over or under inflation will be eliminated, and roads will become safer with fewer blowouts or flat tires. Michelin has been on the case since 2005 when it unveiled its Tweel system. The Uptis is a production-ready version of the Tweel system. For those not navigating such large vehicles, the Uptis will be just the ticket. Michelin further states that these airless tires won't feel any different to our current, very air-filled ones.
