What is the function of torquing wheel lug nuts or bolts to OEM specifications?

Torquing wheel lug nuts or bolts to Original Equipment Manufacturer (OEM) specifications is crucial for several reasons, primarily related to the integrity of the wheel assembly and vehicle safety. By applying the correct torque, it ensures that the lug nuts secure the wheel properly to the hub. This uniform clamping force prevents the brake rotors from warping, which can occur if the lug nuts are either too loose or unevenly tightened.

When lug nuts are not torqued correctly, it can create stress points on the rotor during braking, especially with the heat generated during this process. Over time, excessive heat combined with improper clamping force leads to warping and can adversely affect braking performance, causing vibrations and uneven wear on brake components. Hence, maintaining the correct torque is essential not only for the wheel assembly's safety but also for overall vehicle performance and handling.
