For a seat-of the pants estimate, it takes my chitty CH impact and CH walmart compressor more time and motor restarts/shotoffs to fill up a 33x12.5 than it does to rattle off the 6 lugs holding it on.
Enough air to fill 35-40 35" tires??!! That'll probably run a rattle wrench until you're waaay too drunk to actually drive the fixed rig home. I guess it would depend on the fix, but if you use the impact sparingly, just to rip off lug nuts and break the really tight stuff, I wouldn't worry about running out of CO2 on a weekend.
If anyone's placing an order to that beverage place, let me get in on it and split shipping.
