Adding Tube to tubeless rim

[samjdmosher]

Just the right amount of ether works fine just stand off to the side. I agree with the slime route, that stuff is just plain awesome. I buy it by the gallon now!

Exothermic reactions are a bunch of no fun. Get one started inside a tire and even a removed valve stem can't relieve the pressure before the tire explodes.

The older and more worn the rim, the more sense to give it a tube. (The disadvantage is that if you get a puncture that wouldn't penetrate the tube, it's usually an easy and cheap fix from the outside if it's tubeless.)
