A friend and I had been four-wheeling in Johnson Valley and were finished for the day. I stopped to talk with some other people we saw on the Means Dry Lake Bed, while my friend went out to the highway to air up, using his Thomas 12-volt compressor. Remember, the Thomas is one of the finest and quickest 12-volt compressors around. Anyway, I finished jawing and headed for the highway, getting there as my friend was working on airing up his second 35x12.50R15LT Goodyear Wrangler MT-R. I hooked up my PT10 Power Tank and inflated all four of my 36X12.50-15 Super Swamper SX's from 7 psi to 30 psi, unhooked the hose and stowed everything away. I looked over at my friend and noticed that he was just finishing tire number three and STILL had to do the fourth! The 35" (really 34") Goodyear MT-R's are also quite a bit smaller than the 36" Super Swampers. This proved to me how really quick the Power Tank is and I was sold.

The Power Tank holds liquid CO2. As the liquid evaporates inside the aluminum cylinder, it builds pressure that's expelled as vapor. The outlet pressure is adjustable from 0-150 psi

by the high-quality regulator that's designed specifically for this application. All you have to do is hook up the supplied Power Hose and open the valves. Many people, especially racers, use Nitrogen. CO2 gives you three times the energy as Nitrogen in a given tank size, as the CO2 is stored as a liquid while Nitrogen is stored as a gas. This makes CO2 more economical. Plus, you're carrying a lot more volume with the CO2 in a given tank size. More volume means you'll more likely have the power when you need it in the backcountry.
