About "puncture proof" bicycle tires

[peacefuljeffrey 0]

I know that they make kevlar bicycle tires or somesuch, and I know they have ones with some goo inside that will seal punctures.

I am wondering if anyone makes a solid-foam tire, that approximates the feel and performance of an inflated-tube tire. Are they available, who makes them, and how much do they cost?

It would likely overheat if you go very fast.

I remember they used to sell solid foam tubes for bicycle tires at Wal-Mart years ago, but I didn't hear any good things about them.

They make an insert that slips between the tire and tube that is guaranteed against punctures - its called Green Slime or something. I rode for two months in Baja and never had a leak, and trust me, there are freaking millions of thorns there.

It's good shit. I got 'em from REI.

Back when, 20" bikes were all the rage among kids, I recall seeing them but, only in 20". They may still sell them at bike shops or they may be able to order them. They were a 'bitch' to install but, they did work fairly well. Just that, you had to periodically pull thorns, nails and the like out of them.

I suspect that Green Slime is some sort of liquid you pump into tires, sort of like self-sealing fuel tanks in airplanes.

I have used Kevlar "Snake Skins" in one of my bicycles for many years and few punctures.
My other bike does not have snake skins, so guess which bike picked up a thorn last week?

Is this it ?

urethane can be injected (then it 'hardens') into tires used for forklifts and such in severe tire puncture environments.

The urethane can get quite hot depending on how much deflection the tire expreiences and how fast it rotates. It will also not have quite the same feel as with air.

You can find the solid tubes they sell at walmart.

There could be weight issues with foam. I'm not saying air doesn't weight anything but hey. I don't know the name of the company off hand but there is a company that makes kevlar mix tires that are super light and resist punctures very very well. I believe lance used them. Yeah they ain't cheap.
The inserts that go inside the tube work great, as I had them in my bike for awhile. A friend of mine hates em though, says they add weight. Blah.
