take a straight edge and lay it across the back edge of the rim making sure its not resting on the tire measure from the edge of the straight edge to the back of the rims mounting area. take that number and subtract half of the wheels width, the offset is measured from the center of the wheel so if you have a 6.5" wide wheel you would subtract 3.25" from the distance you measured from the straight edge to the rim this is your offset then you can convert it to millimeters...
