concavity

Hi, I happen to find out that wheel width has only little relation to wheel offset, in that the wider the wheel it can have more concavity ? If its true, that means if a wheel width is 8 inches and an offset of +16, it will be more concave than a 9 inch wide wheel with offset of +26, can...
