Solid tyres should fix that problem!

Hm, now that you mentioned them, I had a google and, of cos, they are
available. I have always known of solid tyres on forklifts and those
solid forklift tyres weigh more than a few grams


Better than pushing your bike home!


Heheheh!! Given the frigging weight of some solid forklift tyres, I'll
push me bike home, thanks

Might have a read of what others say elsewhere about solids. Anybody in
this newsgroup who has used solids and cares to impart some life
experiences?


At one stage the water board had rubber rings about 1"dia to seal the
watermain pipes, off hand the 20" (or the like) did fit tightly when
stretched on the rim - it doesn't take much increase in circumference to
expand to 700 or 27" rims.


Hm, but those rings will probably be quite dense and hard right thru and
will probably produce that "harsh" ride mentioned by Sheldon Brown's
article in the link posted by John Henderson above.


No they are soft (about like the tread on my MTB tyres) as they have to
flex and seal pipe joints.

Then again you could always fill the tube with silicon but solid
silicon, after a lot of flexing turns to liquid again.



But if one was stuck out in the bush with a flat tyre with no spares and
miles from nowhere, I guess one WOULD wish for a solid tyre - harsh ride
or no harsh ride

Ah!

Solid silicon does? I'll be damned, I didn't know that.

at one stage a few decades ago someone promoted the idea of filling the
tyre with expanding foam. The idea being no punctures. Major problem was
low speed limitations, like 30kms/hr. i suspect the other problem was
recovery cycles were too low as I never saw it on the market.


Recovery cycles? Not sure what you mean there.


When the foam s at the bottom it gets squashed. on the way up it
expands, just like in an air filled tyre. If it doesn't, you end up with
flat tyres. Recovery cycles or number of revs in the life of the foam.


I see, them recovery cycles - sorta like how much "springiness was in
the foam" type of "recovery". I had visions of search and rescue
bicycles (that kind of recovery) which went out looking for other
bicycles which had solid tyres which had somehow failed the test -
whatever the test may be.

I'm glad I cleared that one up for me

Eat Mars Bar. Place wrapper on inside of tyre at point of dodginess.
insert tube and inflate, being careful not to move the wrapper. Ride
to use up Mars Bar calories...

...and always carry a patch kit - as well as tubes.


I've used a $5 note to do the same thing. I don't carry Mars bars
around, but I've always got my wallet.

Huh? WTF you carrying on about? What date? Never mind, don't
answer that! What next ride? Where?

You are quite right in that during a social ride, the people one rides
with make a difference and yes, it does sound "blubbersucky"
