It seems like tubesless tires would be a good deal for MUniers, although I never hear about them. Does anyone use one?
There are alot of benefits I can see, no pinch flats, low pressure,
but are there negatives?
The only bad I can see (if it is even a possibility) would be tire fold-over…that sounds possible.
What do ya think?

well ihavnt heardd of anyone riding on a tubeless, but one of my mountain bike magazines, has article in it about tubelss, ill got get and c what they have to say about it for mountabikes, it may help…

That reminds me of a Discovery Channel spot where some 4 wheelers (Jeeps
etc) were crossing part of the Arctic. They constantly had flats from the
bead breaking loose from the rim because of the very low pressure in the
tire for traction.
Their solution to air the tire back up and re-seat the bead was to spray
WD40 into the tire and ignite the aerosol mix with a thrown match. The
resulting explosion inflated the tire with a bang and the bead re-seated to
the rim.
So, stuff a can of WD40 and some matches into your camelbak and head off
into the dry forest…hey wait, maybe that’s not so good…
Anyway, my wheel barrow has the same problem of un-seating the tubeless tire
in my treks across the backyard if the pressure isn’t enough.

Actually, wd40 dosen’t work that great. I use starting fluid when I seat the bead on car tires this way. I learned this from when I was a mechanic in the Army National Guard.
For mountain bikes at least air leakage and tire fit are a real issue. I haven’t heard of any 24" tubeless rims but you could use that “stan’s tubeless kit” or something like that. If you ride a 26" there are some options but I don’t think there is a wide availability of widths.
Ust tubless kit
You can now buy a tubless conversion kit. UST, cant remember who makes it, might be hutchinson.
Basically, special rim tape, special valve, a couple of spoons of glue stuff into the tyre every 8 weeks, pump up and off you go! one kit does ten tyres, or one tyre ten times!
Im going to try it in a few weeks on my trials bike, as im always getting pinch flats, and would be interested to see how it goes.
They do an xc, dh, and road kit!

take this with a grain of salt but…
my entire [no pun intended] tubeless experience is confined to the wheelbarrow and car tire arena, and i’ve never experienced a bicycle or uni pinch flat, but:
wouldn’t a ride rough enough, or air pressures low enough to cause a pinch flat in a normal tube pretty much guarantee the bead unseating in a tubeless?
on an unrelated note [your cue to take another pinch of salt now], how did “yike” ever become the apparently standard alternative to “uni”? bicycle -> bike is an “initial sound, plus hard K (ke)” formula, which would either lead to yuke or yinicucle if carried through from “yike”
i will say, though, that my internet communication encompassing many late-night [and otherwise] conversations with british and australian individuals who refer to post-secondary-education by “uni” from university, rather than the more american “college” as a generic, caused some momentary mental confusion as i was getting into the online unicycling community.
damn. why do my sentences and my paragraphs always end up being congruent sets?
ramble on.

AirFree (tubless) bicycle (or unicycle for that matter) tires are
a solid ring of closed-cell foam - like an enormous O-ring. A
momentary unseating of of the tire would make no difference, so
long as it snapped back in place.

I dont think your thinking of the same thing as originally intended Gardner, As far as I can tell. A tubeless tire system is basically what jimmy explained. They still have air in them, but the tire is the tube.
I think the idea of having a tubeless tire might be good to try for XC and light DH type riding. Although not necacarily lighter than a normal Tubed Tire, there are advantages that I dont care to discuss. If somone tries it i would like to hear about it!
