Those work fine for airing up a tire, but to seat a bead these CO2 setups work much better. The only other thing you need is a ratchet strap. Sure there are tricks where you can use gasoline, starter fluid, etc and a lighter, but I'd rather not burn my beard off. :scared2:
The Power Tank regulator I have is adjustable up to 160psi but I think the adjustability is kind of pointless unless you are going to use it for running an impact wrench. The models with a single pressure would work fine for tires and they are cheaper.
