FYI. PSI is PSI. Pounds per Square Inch. The CFM or Cubic Foot per Minute is the part that separates the men from the boys. The CFM is the Volume the compressor is able to put out, the PSI is the amount of pressure the compressor is able to achieve. For simple and occasional tire pumping and so on a small air compressor is fine. Pretty much any of them will be able to achieve 50 lbs psi. However the less CFM, the slower it will be. Think of it like this: If you used a 1/4 inch garden hose to water your garden, if you put a valve on the end and closed it, you would get a PSI reading the same as your water main. As soon as you turn it on, because of the small hose size, you will get just a dribble and it will take a long time to water your garden. (hows that for a longwinded answer to a simple question!
