Default Spacers and their effect on offset?

Have a quick question.

If I add a spacer to a wheel, it will effectively add positive offset, correct? Say I have a wheel w/ an offset of 45mm, add a 5mm spacer the relative offset would now be 50mm.

Considering offset is measured as the distance relationship b/t the wheel centerline and the hub bore, adding a spacer would decrease negative offset (if the wheel started out having negative offset) and increase positive offset...relatively.

I realize adding a spacer pushes the whole wheel (wheel centerline and hub bore) but for the sake discussion, please help...TIA!

I think you're getting into an area that may be more concerned with semantics than with technical concepts.

Spacers are not usually considered part of a wheel's offset. If anything, they might be considered as moving the mounting surface of the hub, rather than the mounting surface of the wheel. But I think they are more often considered as a separate part, not part of the hub or the wheel.

In other words, in your example, adding a 5 mm spacer doesn't change the offset of the wheel, even though it moves the wheel outward by 5 mm.

Yeah, I realize that. That's why I mentioned "relative."

But I think what you're saying is the same as what I am. Thanks sucka!

It would actually be the opposite. A spacer would push the wheel out farther to the fender, just as a lower offset would. A 5 mm spacer would push the face of the wheel 5mm closer to the outside. So 45mm wheel would appear to be a 40mm offset at that point.

Now like it was said above, you're not really changing the offset, but I think I know what you meant.
