Which means that their grip is not there either. If it vibrates the whole car, that means the whole car is then unsprung somewhat, or if it's merely the wheel itself that "vibrates", that means it doesn't have that much grip either. Neither are good for actual grip. And you can't "air down" the tweel should you find yourself in a bit of mud/sans/snow. Hell, those tweels are much worse than even - very - low profile tyres. They're basically no-profile tyres and have no adjustments depending on load/surface.

It could also mean that since the whole thing flexes they can’t just stick metal weights on the wheel to balance it.

They last 2-3 times as long as a normal tire, have better braking traction than a normal tire... for a car I think they will be great.

I was thinking about the people too.
I’ll preface with NAPALT
But.....
When I go to a car or truck show, everyone comments mostly positive stuff above everyone’s vehicles. A lot of appreciation for others and the car culture in general.
But......
I’ve talked with a few Tesla drivers, and you’d think I was the devil himself for driving a HD pickup.
Do technology and ego share a common WiFi connection?
Again NATeslaDriversALT....but enough to make a correlation similar to those people make about Harley or BMW riders.

I don’t want my vehicle to beep when I leave my keys in it. I leave them in so I know where they are. Maybe the keys could beep when they are out of the vehicle so you know where they are.

Same end result: Less grip.

Not if they're unbalanced. And I bet that "better traction" is in a very narrow set of circumstances.
And they last longer will also be on those slow-moving things. Not on the road.

What?

Oh, and I agree about Tesla drivers (apart from the bolded part, which I'm not sure what means).

You had better call Michelin ASAP and inform them of this so they quit wasting their time.

They apparently agree with me since it's not available for road going or even reasonably speedy off road vehicles.

GM and Michelin will bring airless tires to passenger cars by 2024

Airless tires for everyday cars might soon be far more practical. GM and Michelin have unveiled a prototype of Uptis (Unique Puncture-proof Tire System), a Michelin-made tire intended for passenger cars. It looks like Tweel and other air-free concepts of years past, but its mix of composite...

So, in five years they hope to have solved the problem of having unbalanced wheels which translates to less grip. Yes, they may have solved that in five years time. As it is, considering the wheels are unbalanced and they they therefore have less grip, they are only available on slow moving things.
Nothing in that goes against what I have said so far.

In fact, in that article you refer to, it says this:

[...]its mix of composite rubber and resin embedded fiberglass lets it operate at highway speeds -- earlier options tend to work only when you're slowly putting around.

So, there you have it. Some future product might enable it to travel faster than is currently possible. So far, it is a pipe dream. Can it be solved? Maybe. Will it be as good as pneumatic tyres and wheels? Not really, considering you can't air them down or up depending on load. They're thinking it might see use on self-driving cars (i.e. not really anything "spirited" or varied surfaces).

As possibly heard in a bar circa 1900 about pneumatic tires:

So, there you have it. Some future product might enable it to travel faster than is currently possible. So far, it is a pipe dream. Can it be solved? Maybe. Will it be as good as wooden wheels? Not really, considering you carry much of a load. They're thinking it might see use on horseless carriages (i.e. not really anything "spirited" or varied surfaces).

And it would be almost 50 years before they even heard of a radial tire, another 20 before they even started to go mainstream. It is a good thing the tire developers were not as optimistic as you are or we would still be bouncing around on "good enough" bias tires.

Just because a lot of inventions were laughed at, it doesn't follow that anything laughed at is therefore genius.

And it would be almost 50 years before they even heard of a radial tire, another 20 before they even started to go mainstream. It is a good thing the tire developers were not as optimistic as you are or we would still be bouncing around on "good enough" bias tires.

See above.

I already acknowledged that for slow moving things they can be fine. You even admitted they had vibration as a problem. I then mentioned that vibration is a problem at speed because it translates to less grip (hence why we balance wheels).

You then posted a story about Michelin maybe having a wheel out in five years that would make it possible to go at highway speeds five years in the future


And your response is that people also laughed at pneumatic tyres?

Edit:

Btw. Caterpillar tracks (as on a tank) is also useful on certain vehicles under certain circumstances. That doesn't mean they're great overall and great for going on the road at speed.

 

[85_Ranger4x4]

My response is that people a lot smarter than either of us keyboard commandos think it is viable if they are still working on it and got GM to go along with them.

Even your "evidence" of this is merely that they hope they can solve the problems in the future so it can be somewhat viable for the road.

Of course, it is worth studying, but as of now and the foreseeable future it isn't actually solved at all. It is still only doable for slow-moving vehicles - and most of that is due to the vibration = less grip = less control.

I mentioned the tracks not merely as an example of a different kind of "wheels". I mentioned them, because on a snowmobile (for instance) with a normal track, you have to slow down on ice because otherwise it will overheat the track "belt". Try it on asphalt, it won't last very long at all. These things will have the same added problem at speed.

Tracks are a whole different maintenance nightmare critter...

Track belts aside, keeping the bogies and drives together at speed would be terrible. Let alone steering or having any kind of control.

Due to our recent wet falls they have become the new fad for combines, people put a lot of money into keeping them together on something that only goes 15-20mph (on tires, I think tracks slow them down)

I agree. Tracks are not the solution. It was merely an example of something that also is a problem when trying to go fast.

Yet millions of vehicles have them....and they work flawlessly...

Except all the ones that had a TCM module think the vehicle was not in park when it should be and fire off the brake immobilizing the vehicle until the TCM issue or actual shifter switch is replaced requiring a tow back to the dealer. ?
