What size reserve tank is needed for my onboard air setup to be able to run an air tool to change my wheels? I would like to be able to do it anywhere and just keep an impact wrench in a toolbox. Thanks for any help.
It all depends on the size of the compressor, how much air the tool uses, and how long you want to run the tool. I use an ac compressor in my Jeep with a 3 gallon tank and have no issues with running low on air.

One of the favorites for on board air (OBA) is the York a/c compressor. It's a 2 cyl model with it's own oil sump, which is why its so popular. Should be relatively easy to find as well as it was used for several years on different vehicles.
