What is the recommended torque specification for wheel lug nuts?

The recommended torque specification for wheel lug nuts is crucial for ensuring that the wheels are securely fastened to the vehicle, which is vital for safety and performance. The correct range, typically between 90 to 150 ft-lbs, is based on several factors including the size of the lug nuts, the type of vehicle, and the wheel construction. This range allows for sufficient clamping force to prevent wheel separation while also accommodating for expansion and contraction due to temperature changes during operation.

Applying torque within this specified range helps to prevent issues such as warped brake rotors, uneven wear on tires, and potential accidents due to loose wheels. It is important to always consult the specific manufacturer's guidelines for the vehicle in question, as torque specifications can vary based on design and materials used.

Understanding the correct torque specifications is essential for mechanics to maintain vehicles properly, ensuring their integrity and the safety of drivers and passengers.
