offset refers to the distance of the mounting face of the wheel to the wheels centreline - ie +30 offset translates to the mounting face been +30mm away from the wheels centre line. So in theory, find the centreline of your wheel - measure how far away the mounting face sits from the wheel centreline and that should give you a good idea of what the offset might be.

(positive values are on the outter side (road side) of the centrline , while negative values are on the inner side (hub side) of the centrle line)
