Prasad on FB posted this table which I thought was useful. The zero doesn't seem to precisely track the center?

A lot of broken parts does not make you a racer; it makes you a slow learner.

There seems to be some variation as to the points from which backspacing and offset are measured...ins ide lip outside lip.  I found some charts that agree with the above and others that are a 1/4 inch different.  Must not be a precise science

Way to much thinking going on in that chart. I guess I need to do a video on how to use a tape measure.

It's overly simplistic.  That chart assumes a certain thickness of the wheel at the mounting flange.
