We also used a Powertank inflator when airing up our tires. This unit has a quick connect nipple to hook to our regular hose and then has a clip-on air chuck. In between is a nice 2.5-inch liquid filled gauge and air control valve. The valve allows you to fill, bleed, or check pressure. The pigtail air hose also allows you additional safety to keep your hands away from the beadlock rings when filling.
