Gel, Interesting ! This subject was briefly touched upon in early 2019, do you remember this post which included Bridgestone Airless Tyres. The point was raised by Daewar - Dave

So instead of using free air there'll now be a whole load of extra gubbins in there that'll cost us more?

As Gel mentioned this new developement Michelin Uptis Tire after winning the “Golden Lenkrad” Prize for the “Innovation of the Year” is planned to appear in 2024. Made of Flexible & High Resistance Plastic without Air Pressure, is extremely light and Maintenance Free - Dave

Looks a good idea, but most damage to wheels is usually caused by kerbing them, not sure any of the above would take that sort of punishment.
Past cars Mercedes B Class, S Class, E Class Estate, E Class Coupe, G Wagen, 260E interspersed with Peugeot 406 and Audi Coupe.

Qashowner, Good Point but the priority appears to be as quoted below, I have not really picked up any comments with regard to Kerb damage - Dave
“The prototype name for this in-development product is Uptis, shorthand for Unique Puncture-Proof Tire System.
Compared to a conventional pneumatic tire, the Uptis offers numerous benefits. The most obvious of which is never having to deal with a flat again, so feel free to run over as much broken glass, miscellaneous debris or even drywalls screws as you want. These tires require no maintenance, no periodic air-pressure checks. Any vehicle fitted with Uptis tires can do away with a jack, spare and any tire pressure-monitoring hardware, which saves weight and cost, two things automakers absolutely hate.”

Well isn't that dog ugly. Imagine what thats gonna be like to keep clean, it'll make cleaning complex alloys look like wiping down a kitchen work surface lol.

As far as I am aware they would be encased in rubber so would look like a normal tyre.fbgqashqai wrote: ↑Thu Sep 16, 2021 9:44 am Well isn't that dog ugly. Imagine what thats gonna be like to keep clean, it'll make cleaning complex alloys look like wiping down a kitchen work surface lol.

Just a comment on the Wheel - Dave
Designed for passenger cars and small SUVs, Uptis (Michelin calls it an "airless mobility solution") takes an aluminum wheel assembly and wraps it in a composite material mixing rubber and a high-strength resin embedded fiberglass. Instead of an air-filled rubber tube, a series of "spokes" hold the weight of the car and provide similar handling and performance to a standard, air-filled pneumatic tyre, says Michelin. Aside from the obvious benefits of not needing to worry about having the correct amount of pressure in your tyre, improving fuel economy and promoting even wear, there are sustainability benefits as well. The tyres will last significantly longer, not least because Michelin aims to develop a 3D printing system to allow a new tread to be applied to an existing Uptis tyre.
