Anybody have any experrience with the co2 tire inflators. I saw a couple of them on rocky mountain atv, but I have yet to see one in person. This past weekend I was at glamis and one of my rear rims is bent. It had a slow leak and I would have loved to have one of the handy. I was in the middle of nowhere and realized my tire had like 1psi in it. How many tires could you air up with lets say a 16g cartrige. Is it enough to seat a bead? For the price they seem really convenient (sp?).
