Abstract

The wheel offset measure has three straight edge rulers that are interconnected for use in measuring the offset and backspace of a vehicle wheel. A mounting rule is used to hold a rim width rule and a backspace rule and to bridge the diameter of a wheel rear flange. When in place on the rear flange the rim width rule is set to the dimension of the rim width. The backspace rule is then adjusted to touch the mounting pad of the wheel. The relative position of the centerline end of the rim width rule and the zero end of the backspace rule are used to read the offset in millimeters. The backspace dimension can be read from the backspace rule relative to the mounting rule.
