What is the recommended torque specification for wheel lug nuts?

The recommended torque specification for wheel lug nuts is typically in the range of 90 to 150 ft-lbs. This level of torque is necessary to ensure that the lug nuts are sufficiently tight to hold the wheel securely in place while still allowing for the removal of the nuts without excessive force that could damage the threads or the wheel itself.

When lug nuts are not tightened to the proper specification, there is a risk of wheel loosening during operation, which can lead to wheel detachment and pose serious safety hazards. Conversely, over-tightening can cause damage to the wheel or lug nut threads, lead to distortion of the wheel flange, or even result in the potential for cracking.

The range provided by the correct answer accommodates variations in wheel and vehicle design, as different manufacturers may specify particular torque values suited for their equipment. Therefore, it’s always best to refer to the vehicle manufacturer's specifications, which often fall within this range, ensuring safety and reliability.
