Spoke Tires

Okay when can I expect to get airless bike tires?

They already make airless bike tires.
Not sure what your pic has to do with the title of your post, since NO tire is shown.

There is a tire...look closer. It's just on a car.

Bill,

Do you just pop in this forum any time you feel you need to take a dump on a thread? Seriously I have never seen you post a single positive thing.

That's a pretty rad concept. Might be tough to implement for a bicycle due to the necessary spoke length vs. rim width; unless you were doing something like using a 650b or 26" rim to mount a 700c version spokey-tire onto.
Which seems pretty awesome.

I wonder a few things:
1) What can we expect for bob factor compared to or in conjunction with modern quad-linkage suspensions?
2) Can it compensate for a shorter travel suspension by adding "tire travel" upwards of 2.5 inches if you used a 26" rim for say, a 29er sized tire? Essentially making an XC/Trail bike more like an Enduro, with the exception of the laid back HT angle.

I see the picture, but I don't recall those being an option when I bought new tires for my pickup earlier this week, either. The moral being: There's lots of things that sound good, but that doesn't mean they work well.

Keep in mind that we DID have "airless bike tires" prior to the wonderful invention of the pneumatic tire around a hundred years ago. As far as I know, none of the old high-wheel bicycles ever had pneumatic tires, and the first generation of "safety bicycles" were likewise on airless tires as well.

Yea I figure the rim size will be a few inches less than the ending "size". The real question will be resistance, and if it takes more force to move them. The car tires are scheduled to come out mid August I believe. Somone will do a fuel consumption test on them, and we should know how effecient they are at that point. Solid tires kill performance and I expect these to be a touch less efficent than current tube/tires, but if they can get it close it may be worth it.

Those wheels were on less expensive bikes when I was a kid, I know cause my dad is a cheap azz and bought me the cheap stuff.

I'd think they are a real rough ride. Not to mention a few years bak there was a product called a "snake charmer". If I recall correctly, it was solid piece of rubber inserted into the tire in place of the tube. S'posed to eliminate flats but the problem was weight and a poopy ride.

Maybe he did miss the tire in the picture but I'd have to say I've seen BillP dish out lots of advice throughout the forums.

I think it is possible to make that design as comfortable a ride as a tube and tire, but I doubt it will be. I would think they would have to have weight ranges for the tires and the supporting strips would need to have enough give. I would get them if it was efficient enough and close in comfort. If they can't get close in either category they won't even be considered.

I hardly doubt they could ever get close in comfort etc. Tires can feel different ( I am told) by the threads per inch (TPI) of which they are measured. I could not see them even coming close tyring to match a flat strip of tire with a large solid cylindrical structure.

Looks to me like there's all *kinds* of air in those tires.

I can see the appeal for military and off-road applications where there's more of an issue with normal tires getting punctured. But for regular highway use I doubt they'd match either the ride comfort or efficiency of pneumatic tires. These Michelin 'Tweel' tires were one of Time's 'inventions of the year' back in 2005 and I don't expect to see them take over the tire market anytime soon.

Search in commuting forum, there have been a ton of threads on airless tires (not to be confused with tubeless tires) over the years Bottom line is that they don't flat but they are difficult to put on, have poor ride and even poorer traction to the point of being dangerous. People try them and then say no way.

so far a cool idea that has not had a truly workable implementation.

The traction issue might be solvable with this implementation, though. The big problem with airless tire traction is the compound the tires are made from. With this structure, you could feasibly use a standard tread compound on the outer "tire" section while using a harder durometer compound for the body of the tire and the compressible spokes.

I agree with Beans that the ride would likely still suck in comparison to a pneumatic tire, but it could be workable.
