Why must wheel lug nuts be properly torqued using a torque wrench?
When installing the wheels on a vehicle after servicing, it is important to torque the lug nuts properly. Lug nuts that are not tightened correctly can ruin wheels, affect rotor runout and can be deadly if the wheel comes off or studs snap. Over-torqueing the lug nuts does not affect runout immediately.
Can you over tighten wheel nuts?
Excessively tightened lug nuts can strip the threads, distort brake rotors, damage the wheel, and possibly shear off the lug stud. Insufficiently tightened lug nuts can come loose, with catastrophic consequences.
