kobalt CO2

[Dirty VooDoo]

I just saw a cool new tool at Lowes, it's a 20oz CO2 tank. It comes with a regulator, hose and a box to store it in. I was wondering if 12.6 square cubic feet would be enough to air up my 285/75/17 tires from around 22psi to 35psi. by my caculations it should be able to air up about 7 tires. The whole kit is about $85 and about $8 for refills. Do you guys think this would work? If there is something I may be overlooking please let me know.

It may work, but you need to remember that as soon as pressure equalize, you won't be able to air up the tire anymore. So your calculation of 7 might be a bit generous. Refill is kind of expensive for 20oz. I fill a 10lb tank for $17.
