airless tires

[tri again]

Just caught the end.

Science channel, "how it's Made".
Looked like expanding foam, poured and spun into molds.
Thought it might be lil' red wagon tires but they mounted them on metal wheels and then flashed on the entire line of airless tires.

Looks like all the way from bicycle tires to actual car tires.
"last 3x longer", whatever that means.

I've seen them for wheelbarrows for a few years now but they look
interesting.
Wonder if they can duplicate low pressure types.?

they make them for bobcat and other skidsteers. I used to wish I had them at the roofing company I worked at because I would have spent a lot less time plugging tires. However, after operating one with a set, they only work on pavement or gravel. they make the machine an absolute gutless wonder in any kind of wet dirt. and they just sink in heavy mud. I was quite surprised because they still had a very aggressive tread pattern. I had heard this from other mechanics and they were definitely right.

I had those for my bicycle in 1989. For bikes they were called "no more flats" and they were heavy, unforgiving(bent my rims) and it was difficult to get the tire to bead correctly.

The new wave and style of airless tires has been being utilized by the military for some time now, check out the new polaris quad with similar tires, can't remember the model but its the big one.

EDIT: its the 850 H.O. model

I can see them for areas with lots of nails but also think that running the 4wd jeep in the sanddunes, we lower the air pressure significantly.
If we spin or get stuck, lower the pressure and off we go.

Maybe softer is better?
Better living through chemistry.

Yeah I had a mountian bike with a pair of those in it back in 2000... HARD 2 PEDAL... lol I could not go real fast and it was hard to get rolling..

Are they like these? I saw something about this years ago, but I don't know if you can get them for a car yet. They look pretty cool.

Those are the newer style, supposedly much better than the foam inserts/solid foam tires because of weight and flexibility.... same basic idea as on the polaris 850 H.O.
