just to add to this......remember the stated width of a wheel (eg 7") is not always the actual width. I know with later cup's a 7" wheel is actually 8" between outside edges. The 7" refers to the tyre mounting surface.
This is only important if you are really trying to squeeze a fat rim into a small place
