WORLD FIRST - Airless Car Tire! Michelin Reinvents The Wheel

World's first airless car tyre! Introducing the Michelin UPTIS - a puncture proof tyre designed to reduce wasting perfectly usable tyres that could otherwise be scrapped due to damage.

Tire sidewalls are definitely needed. The reporter was so enamored with the concept he didn't ask any hard questions:
- What happens to balance if mud or debris gets in those open parts of the wheel
- Does the wheel develop flat spots if it sits for a while - especially in hot weather on asphalt.
- What happens when one of those "spokes" fails? How does that affect the performance? How many have to fail to need a new tire?
- What is the primary reason (so far) for failure? Speed, road conditions, etc.. Need to know that so you can determine if it's right for you depending on where you live and normal road conditions there.
- What is the maximum weight limit? Are there different sizes for different uses? Cars, SUV's, light trucks, etc. And do they all perform similarly?
- How long do these normally last? What is the cost/mile compared to conventional tires?
- What are temperature limits for use (cold limits and heat limits) before the tire warps, becomes too stiff or deforms enough to become unsafe?

Definitely sidewalls. Without them, debris/snow would get in between the spokes and make the tires imbalanced. Also, the tires would be less aerodynamic.

[GordMcknob]

100% definitely sidewalls required ! Once you go through mud or gravel its going to clog inside the spokes, then the balancing will be out the window 🤷‍♂️

[PerplexedPhoton]

I think we'll need sidewalls for anything other than dry road use. Stuff like snow and gravel will probably get stuck in the tires.

This technology has been around for so damn long now. Every couple years it gets announced again as 'amazing new tire technology', never gets released, and then a few years later the whole process starts again.

The first airless tires were solid rubber on a wagon wheel. : )

I swear I've been seeing someone invent "world's first airless tires" every year for like 2 decades now

[StrikeTheRoot]

this technology is literally decades old.

[RAWDJ]

I would be interested in seeing results performed by aggressive steering, breaking, and what happens to the tire and rim combo in a crash.

[paulhowell]

I remember seeing these in a car magazine about 10 years ago!!! Taking that long to develop. 👍

[wrayjordan]

Odd? They developed this about 20 years ago called them Tweels. Used on off road construction machines like Bobcat or fork lifts. Glad to see they are still working on them. Really cool.

[ronniepirtlejr]

Whould the snow and ice get stuck inside of it and affect the driving?
How about highway speed?

[Braydenplaysallday]

Never could understand how over a century has passed & we still haven’t figured out a way to improve a tire to avoid flats. Thank you Michelin!

[LexingtonDaniel]

I've been seeing this sort of design for about a decade and I'm glad to see them hit the market. I'd say put the sidewall on to keep debris, rocks, etc. out of the vanes. It could be a porous material, but they need to keep larger objects out to prevent damage.

[will-i-amb.]

This is a great idea! Specially for the commercial industry or cars that drive under 80mph!

[dafashoso]

The title is completely misleading, there have been airless tires of all types of shapes and sizes for over a century! The original purpose for the design of this specific tire was because NASA approached Michelin to design an airless tire to be used in the Mars Rover over 10 or 15 years ago. The tire was meant to not hold any air and withstand the harsh temperatures of the planet. Years later, this design was released to be used in industrial vehicles like skid steers and such. Ive seen videos of civilian pick up trucks testing these out on streets. The video title should be, Michelin releases their airless tires to the public!

I bought two tiny Michelin versions of these tires for my zero-turn mower this year. They were $1600 a PAIR (2 tires). That's $800 a piece for tiny versions of what you see here. They tell me they will last three times longer than a conventional tire. I very seriously doubt this will be the case for a passenger car tire. EDIT: I have noticed that, over time, the fiberglass "spokes" slowly lose their height and are now considerably "lower" on the sidewall that they were when I bought them. They still drive "OK(ish)". I'm not convinced yet.

[atarparker]

The design for the airless tire has been in existence for WELL over 100yrs. The fundamental design featured in this video, has been a thing for ~20yrs to my knowledge; maybe more.

[robru]

How does it cope with different weights (i.e. when a car is fully loaded) if you can’t adjust the pressure like you would on a regular tyre?

[tinashetf]

This tyre looks great without the sidewall. Allows everyone to appreciate the ingenuity it takes to make one of these. Can't wait to have those on my car
