Along with wheel diameter and backspacing, you must also know the wheel width. The diameter and width are directly related to what size tires will fit your wheels and how they will bulge out over the rim. A wide tire on a narrow rim is harder to mount and can give a slight bulge to the tread depending on the tire, but it also protects the wheel with its bulge. We have found that many tires that recommend a 10-inch-wide rim can be mounted on an 8-inch, while those that recommend a 12-inch rim shouldn't be mounted on anything less than a 10.
