Using CO2 is only a "quick" solution to airing up, in 1 week you will loose a minimum 5 psi as the gas leaks through the tire rubber, eventually it will all leak out. You'll have to let it all out & do it right with atmospheric air eventually.
I use a Viare continuous duty pump, be sure to get the continuous duty pump. Takes about 20 minutes to go from 20 psi to 38 for all 4 tires.
