Maybe this will help.

A 15x7 wheel with 4" backspace       0 offset

A 15x7 wheel with 4.25" backspace    6.3mm offset

A 15x7 wheel with 4.50" backspace    12.7mm offset

A 15x7 wheel with 4.75" backspace    19mm offset

a 15x7 wheel with 5" backspace     25.4mm  offset


After a lot of searching, the generally accepted +/- offset deal is best
looked at as front wheel drive cars have positive offsets.  Older rear wheel
cars tend toward negative offsets.  A "deepdish" or "chrome reversed" wheel
has a NEGATIVE offset.

Is that any help???
