What do you think about the new 'performance wheels'?

In the few years there have been several companies working on a new non-pneumatic tire. They consist of geometric shapes that give them the support needed to support a vehicle, but still have some flexibility so that they are not stiff as a rock.

I was just wondering what the capabilities of these new tires would be for wheeling. Whether that be rock climbing, mudding, or just trails.

Here are some links for more information. Tell me what you think.

It's a good idea. Those companies obviously think it's worthwhile enough to invest research capital. We aren't going to be able to bring much to the table because I doubt anyone here has any firsthand knowledge with these. The question that comes to my mind is one of adaptability. Will a single set be capable of highway performance and acceptable trail performance? IDK.

I would think for mud and snow you'd want those sides covered up. But I bet that is some light weight stuff.

I can't see this going anywhere though. Is there really a serious enough problem with normal tires to warrant the cost of development??

Im presuming yes, the reason for that presumption is because they say that they can attach almost any tread to this wheel. And so they could just attach a tread suitable for both on and off road.

I think that once they get further into the process of developing these wheels, they will also develop a curtain of some type to protect the spokes. Especially since they're also developing these for the military.

Some of the positive things i see about these are the ability to warp around objects like rocks. For rock climbing it seems like you would get a lot better traction.

Also in one of the sources i noticed they said it was possible to easily retread and to change the tread for the desired purpose. Now i dont know if that was easy for the company to do, or easy for people at home to do with the right tools. But that seems like a fairly good idea.

Edit: forgot to add, the reason they are making these in the first place is for the military vehicles having wheels tough enough to survive IED's. That means that the only time you would really need to replace these tires would be for tread wear. Never any flats. And you only need to replace the tread for that, not the whole wheel.

As a former military mechanic, I can see them being great for military use. No more heavy *** run-flats and bead locks. No more tire leaks, punctures, safe from small arms fire, no more sidewall checking (you wouldn't believe how many full tread tires I've replaced for weather cracks). Survive an IED? I'm not a believer...

For our off-road use I see the big defficiency being you can't air down. Same deal for the military CTIS (Central Tire Inflation System) but that's NOT a bad thing

For those of you that have never been cursed with (maintaning) CTIS it's a JOKE. The real reason the DoD bought it is they figured it would save money on tire wear. 'Not for cross-country mobility, otherwise you wouldn't procure a truck with open differentials on all axles.

yea those have been out of quite a few years. excellent idea, makes lots of sense to me, especially military, farm/ranch and off-road construction or mining use.

it doesnt need to be aired down theres no air in the darn tire. that makes it perfect for off road use because its already flexible enough!

It will be neat to see this application for practical purposes hit the market in the future.

I think I read that an average tire takes 4 gallons of oil to make? They may be able to use recycled plastics (cheap, available material) for the wheel.. It seems to me that once development is completed, tires could be produced cheaply. Lastly, I'd assume these wheels are lighter which should improve fuel consumption. If this is true, it makes financial and envornmental sense to me.

I wonder how well the balance is after you get a little mud clogged in there.

Although I yet to see much indepth technical information on these (didn't Popular Science have a buzz on these YEARS ago). I would believe the flexibility of the tire is designed in and cannot be change like we do be adding or subtracting air pressure. That being the case a tire designed to be roadworthy will not be flexible enough for extreme off road use (and vise versa)
