Hub diameter is, therefore, an extremely important consideration when fitting new wheels, whether OEM or aftermarket. If the hub diameter is smaller than the axle, the wheel will simply not fit. Most aftermarket wheels are, therefore, made with larger hub diameters to ensure that they will fit on a wide range of cars.
