Today I split a 406 tube down the middle and used a wet rag to clean what appeared to be talcum powder from the now exposed inner surface of the tube.
It was "fun" to stretch it to go around my 622 Velocity Dyad rim and took me some effort to get it done.
I did my best to make sure the excess that overlapped the edges of the rim, were evenly spaced by manipulating them by hand and then I added the tire.
In this case it was a 2.3 Exiwolf folding tire (not tubeless specific).
I emptied a small bottle of Stans into the tire by lifting a small section of the tire via three levers.
I refilled the small bottle of Stans and used its applicator lid to pour a little fluid around the edges of the tire to help with the sealing process.
I didn't have a compressor but managed to get the tire to blow up using my hand pump.
I put 30 psi into it and proceeded to spin the wheel trying to get the inner surface of the Exiwolf tire and the split tube coated.
I hung the tire on a hook from my garage wall and went indoors to watch TV for an hour.
I just went out to check on it and the tire is still hard.
I gave it a few more spins and have left it hanging again.
Its nearly one am here in Western Australia and I'll check the tire again in the morning to see if its held its air.
Its my first attempt at ghetto tubeless and I'm optimistic at this stage that it'll still be firm and sealed in the morning.
If not, I'll try again.
