The wheel does not have a mounting disc with tapered lug nut hole (it is a flat disc and in doing so that the rim and hub will center true at all times when the tire and rim are mounted.
Wheel studs are ment for wheels that have dished lug nut holes for tapered lug nuts (for an automobile for example)requiring high torque values and it is easier to torque the wheel bolts and set them with blue Loctite which allows them to come off when you want them to come off rather than when they want to leave the axle hub.
