Homemade Tubeless Tires
Air will escape, one of the biggest problems with Ghetto tubeless (unfortunate, but long established name for this technique) and not using specific tubeless ready or UST (tubeless standard) tires is that you need to inflate your tires a lot. At worst for every ride.
The tires often do roll off the rim. Not every combination of Ghetto tubeless will work (the internet used to be full of lists) so it's about trial and error. It's always been recommended to do the rear first and ride for a few rides before doing the front. If the rear tire comes off you may be able to stay up right!


Higher pressures (+40 psi) are worse for tires rolling off.
