Airing up tires is a trail-end pastime, and when you're moving between multiple vehicles it's hard to beat a Powertank. We've run them on lots of project vehicles and every year there seems to be another great upgrade. The new 15-pound tank is filled with compressed carbon dioxide, and now has liquid-filled gauges and a heavy-duty tire inflator with a 60-psi gauge, and it comes in a handy carrying case so that it doesn't bounce around and damage the tank. We know firsthand that severely dented tanks won't be refilled, so always use a proper mounting bracket to secure your Powertank in your vehicle. The Powertank quickly filled our tires and had us ready to hit the road to find the next mud hole or rock pile.
