Time to Fill a Tire by CFM Calculator

To estimate the time to fill a tire by the diameter of its rim we first calculate the volume of the estimated form of a tire. We then calculate the volume of atmospheric air (ft3) needed to fill that tire and divide that by the given CFM to find the time in minutes. We calculated labour costs assuming a $45k per year salary. Note we changed the form estimation on the super single and CAT 797 tires to account for their larger form.
