Wheel Lugs

Wheel lugs are the large bolts that go through the wheel rim and secure it to the wheel hub. They are pressed into the hub from the inboard side so they cannot pull out when tightened. The Lug nuts thread onto the wheel lugs, clamping the wheel rim between the hub and lug nuts. It is extremely important that the wheel lug nuts are securely tightened! If they are not -- your wheel will come off! Over- tightening is also a bad idea; it can prevent you from being able to change a flat tire.
