I wouldn’t say we dismissed the CO2 tank idea (although I have an engine mounted York). I calculated that number (40 tires) when inflating a bigger than average 31”x10.5 tire from only 10 PSI to 30 PSI. In a real expedition you will only re-inflate to that pressure when you hit the tarmac again. For your other 10 times you will only re-inflate to say 20 PSI after getting unstuck. And will you really need to re-inflate 10 times? I’ve been on some long trips and I never had to inflate more than 4 times. And that includes the great sand sea.
It’s a great option for those who don’t want, or don’t know how, to modify their engine bays to accommodate an engine driven compressor and want something faster and more reliable than an electric one.
Take a look at the charts on this page: http://www.powertank.com/chart.htm
A Sanden compressor will work too and has a much smaller profile, however it will need to be oiled often as it doesn’t hold oil as good as Yorks.
