Airfree Tyres

Not exactly air free however you might consider
searching this group for [puncture fairy] for many
tales of less than usual air.

Are they solid or foam-filled tyres, promoted as being unpuncturable?

I don't know anything about current ones, but I tried some about 20
yrs ago and found they were very heavy and gave a very rough ride.

I'm sure that I read that they sometimes come off the rim.

I could be wrong though.

There are a number of types; the type I am familiar with have a sort of
cellular structure rather than being absolutely solid. Nevertheless they
were exceedingly hard to get on and off the rims, and their ride and
performance was extremely poor.

Unless you have a particular and exceptional problem with punctures I'd
recommend against.

They generally give very poor comfort and grip.

And even then only if you've tried something like Marathon Plus or Dutch
Perfects and /still/ manage to get holes.

Not since I was 5, and I don't feel inclined to try them again.

Just tried to help someone fix a tubeless tyre, and I'm not too
impressed with them either. They are great until you have your first
puncture, but then finding and fixing it seems impossible. We found a
hole and patched it, but couldn't pump the tyre up, either with a good
track pump or CO2 cartridge. No idea if this was because there was
another puncture we couldn't find, or because we just weren't getting
a good enough seal. So the tyre now has a tube after only a few
hundred miles, might as well have bought a tubed tyre to start with as
far as I can see.

Garage air lines have their uses. :-)

What about the technique of setting light to a bit of petrol?

I've seen it done with a can of lighter gas - I think it would be harder
to get a good air/fuel mixture with petrol, and butane might not be so
bad for the rubber.
