• Airless the future of tires? Michelin Uptis puncture proof tires

      They say you can not reinvent the wheel but you certainly can reinvent the tire. The Micheline Uptis is certainly a new take and as you can see in the photo it is not a traditional tire design which is inflated with air.

      What is the benefit?

      Michelin will be able to 3D print these tires in the future. That means reduced cost due to less materials and the ability to create tires quickly.

      The BoostAddict question is, how do they perform? For autonomous city cars or buses we can see the use but will these tires outperform a traditional high performance tire? Doubtful.

      Lower costs, no blowouts, and less maintenance sound great. You will not be able to change the pressure though so this is one size fits all and not for everyone.

      Expect to see applications in the real world as soon as 2024.

        Do they come in white wall?

        They showed this type of design around 10+ years ago and nothing came of it, sounds like a publicity stunt but let's hope something comes of it.

        The production version will for sure need some sort of sidewall to keep rocks, mud, sand, ice out of there which will damage the supports and cause huge imbalance and wobble at high speed.
        Also the downside is way more unsprung weight so this will only really be useful for low speed stuff like mentioned where durability and reliability are the biggest factor (slow around town electric busses, fork lifts etc etc).

        But like you mentioned, not being able to reduce tire pressure to get better contact patch would rule these out for even slow speed off road usage where you might be tempted because they are immune to puncture.

        These are honestly already used and available on fork lifts and skid steer loaders and tele handlers

        Imagine the drag these tires will cause. Your gas mileage would be totally hit.

        These wont work for normal cars for many reasons. Waiting to see the cornering video ...
