Used to understand this a lot better than I do now it seems. When dealing in offsets, my car currently has a 10in wide wheel with a + 22mm offset. If I bought a wheel that was 10" wide and had a +25mm offset, I am moving the wheel outside lip 3mm closer to the outside of the car correct?

Also if I bought a wheel with a 10.5" wide but the same 22mm offset I would moving the wheel 1/2 of the .5" (6mm) closer to the outside of the car correct?
