The important numberfor the rim is the inner width, the spacing between the inner edges of both bead hooks. To measure it the tire must be off. Typically a tire shouldn't be less than maybe 8 mm wider than this number or more than maybe 20 mm wider - I don't know the precise numbers. But it's definitely based on the inner width. Few bicycle rims, if any, have inner widths as large as 28 mm.
