Somehow all of the "guides" for finding back spacing and offset don't seem to make sense between their examples and their formula.
This site for example. In their chart they list a 5.5 wheel with 3.75 back spacing as having a 12 mm offset. They say to find the offset that you subtract centerline (5.5 / 2 = 2.75) from back spacing (3.75). Which gives us (3.75 - 2.75) 1 inch. Which converts to 25.4 mm, NOT 12 mm. What I'm I missing? |
