tubeless and airless 700c wheel

Make sure you post the result of this.

it looks really interestin.. but you can't change the air pressure, and
i don't know if you even could take it off the wheel without harming the
tire or the rim...

Sounds a lot like the foam-filled bike tyres (usually orange) that were
around in the 1980s. These seemed like a good idea, but felt absolutely
horrible to ride on. There were also foam hoops that were supposed to
be inserted into a normal tyre instead of an inner tube, but these
suffered from similar nasty feel. It would be good if these people have
come up with a better solution though.

I've ridden an airless tyre on a bike and it was like riding on the
rims. My dad used them for a few months but then decided to take them
off as they were causing more problems than they solved, loose bolts
from being bumped so much, aching arms from vibration and they had
really high rolling resistance so they made it slower to get to work. A
bunch of people have come up with these and they've always been rubbish
so far.

I don't really see the point of it anyway, it's pretty much guaranteed
to be heavier and slower rolling and punctures aren't a problem on a
well set up road unicycle, so you don't really gain much.

maybe this is an improvement over the older style of "flatless" tires,
but i doubt it. in order to deliver a comfortable ride the tire needs to
flex and absorb the minor road shock. this is obviously accomplished
with air. Even on a super high pressure track bike, that little bit of
cushion would suck to lose.

my assumption is that with no give in the tyre the rim would really
start to suffer. though on the news show they had MTB and RoadCouriors
try it out and they were all intrigued. the Wreches they showed it to
all dissmissed it as somthing that would suck to ride on though witout
even riding on it.

the sample i am recieving im sure will be just a smaple peice of the
tire not a whole tire. if i had a 29er i would probably pay the 20$ just
to test it and well have a john deer yellow tire!

These tires do have air in them, but it's in the closed-cell foam. Like
a tire made out of hard seat foam.

The main two questions are how hard, and how heavy? My guess at the
answers is medium-hard, and heavier than a regular tire.

In general when I've come across airless tires in the past, they have
been aimed at the idea that flats suck. Of course they do, as I can
attest after the several-mile walk I took out of my last ride in
Auburn.

For people who are more concerned with flats than anything else, these
tires should be perfect. For those of us concerned about weight and
performance, they will probably not replace what we've got.

I have one of those solid foam innertube replacements hanging in my
garage. My original intent was to possibly make a half-wheel out of it
someday. But there it hangs. More interesting for shows would be a
one-and-a-half wheeler, like Jack Halpern's "150" of 1982. Scroll down
this page to see:

Now *that* was a cool unicycle. He later turned it into a simple
half-wheel, but that thing was no fun to ride, and could be very hard on
floors.
