if the tyre stays on the rim
thenit is just folding over
means you need to change your style or put more air in

Theres a link to the photo. It just looks like that. (obviously the
tire is deflated in this picture). But yeah it just comes off at a spot
and then because the tube is inflated it pushes the whole tire off the
rim about 20 seconds later. Its really annoying. I am sorry if i didnt
explain it well enought.

the easiest fix that I can think of is glue it on. I think there are
glues made especially for this but I don't know what they are.

Thats a good idea minus the fact that if a get a punchered tube what
happens then? I was thinking of gluing it but i don't know. So this has
never happened to anyone?

I noticed that you don't have th KH47mm rim. With wider rims the tire
stays on better when doing sidehops and unispins. There is less
foldover which can remove the bead from the rim. Put more pressure
intothe tire - Inflate it more. Don't glue it on. Check to see if the
rim is bent anywhere and that it does not have any grease or oil
spilled on it.

Yeah im dead set sick of tire and rim problems so i might just buy the
KH47mm rim. And through out whatever opne is on there. I have been
doing 5 foot drops with low tire pressure (which is stupid) so this
muight have damaged the rim. Any other suggestions?

Yea this happened to me with my old CC. I've got a GP uni with really
little tyre clearance on the frame so first I noticed the tyre rubbing
on the side of the frame a little bit, then eventually it got so bad it
did exactly what yours has done. It's due (or was in my case at least)
to the bead of the tyre (the ridge that goes into the rim and keeps the
tyre's shape) being a bit bent. I'm not too sure how or why this
happened, but if you take the tyre off you can bend the bead slightly,
but I found this only helped for a short while. I just bought a new
tyre to solve the problem because my tyre was almost bald and I needed
a new tube anyway. So I'm not sure how fixable this is in the long
term.

Hope this is any help

EDIT: I just realised you have the GP frame too. I just saw the moment
hub and assumed it was a KH. Do you notice the tyre rubbing on the
frame at all?

Haha.
Funny you should mention that. About a week ago i filed the arch way
bit down a heap because it kept rubbing whenever the wheel alignment
got even a milimeter out. I am unsure should i buy a new KH Rim? Then I
will only need the frame to have a 07 KH uni. Haha OR buy a new CC?? Or
is there some quick and easy fix to this problem? I need it fixed in a
wekk cause of the brisbane ride!

It could be either the tyre bead or the rim.

Look at where it is coming off the rim, does the tyre bead have a nick
or bend in it at that point?

Does the rim have a nick in it, at the bit that holds the tyre bead
on?

Is it always coming off at the same place on the rim (stick a sticker /
mark the tyre and rim where it does it and then put it back on and ride
some more)?

It could also be the way you're putting the tyre on. You can check once
you've put on a tyre that it is on okay by looking round at the little
line that goes all round the tyre above the bead, and checking that it
is at the same level compared to the rim all the way round the tyre.
Particularly with trials and other wide tyres, it's easy to have a bit
of the bead not hook on.

It also could be the tyre pressure. If you're running very very low
pressure, that can make tyres fall off. If you've been doing drops and
hitting the rim, that's a sign your pressure is too low.

In an emergency gluing is an option, I know of people who've used
superglue for this, but it won't hold for long. Best just make sure the
bead is seated and then pump it up slightly harder than you usually
do.

It is possible to break the wire bead in the tire or at least stretch
it. You can break the bead if you use metal tire levers and are really
aggressive in how you take the tire on and off. Some trials tires can
be really tight on some rims so it is tempting to get really forceful
in leveraging the tire into or off the rim.

The bonding in the tire can also come undone and cause the tire to
stretch out to be larger than it should be. If that happens with a new
tire it is a tire defect. If that happens with an old tire just
consider yourself to have used the tire up for its useful life and
replace it.

The tire has most likely been removed while the bead was still seated
properly the rest of the way around the rim.

We had a car tire do this in my Auto class.

I also recall reading someone on the forum having this happen in cold
weather... most likely due to the rim shrinking slightly, and the tire
staying the same size.

It looks like the only real fix is a new tire. I agree with ^ that it
sounds like the wire hoop inside the tire, that should hook the rim,
has become enlarged somehow.

Glue will make a mess, and is unlikely to help.

flip/spin the tire on the rim, i had to do it a few times when i rode
the nimbus rim. also, i liked to glue my tire on. i don't have a
problem with the tire on my KH, but the rim ... can't say the same.
i use a motorcycle tube for my unicycle, i always pop a normal tube the
day i get it.

the only way i have popped a motorcycle tube is cathching the last step
on a 12 stair w/ low pressure. it actually flatspotted the rim a little
too. even then the tube had a slow leak that took about a day to go
completely flat.

the tube size you will need is a 15x2.5-2.75

glue.... i want to suggest a (VERY) small silicon bead ... air up tire,
wait till it dries... have at it.
