Lug Nut Torque
Torquing lug nuts and lug bolts correctly is a crucial part of the tire and wheel assembly that ensures smooth ride and safe performance of your vehicle.
What is Lug Nut Torque?
Lug nut torque, also known as wheel torque or lug bolt torque, refers to the amount of force required to tighten the lug nuts or bolts to secure wheels to the hub of a vehicle. Torque is measured in foot pounds (ft-lbs), Newton-meters (Nm) or kilogram-force meters (KGFM).
How Much Torque is Needed for Lug Nuts on My Vehicle?
The recommended lug nut torque can vary depending on the make and model of the vehicle, as well as the type of wheels and lug nuts being used. Generally, the recommended torque range for lug nuts on passenger cars and light trucks is between 80 to 100 foot pounds (ft-lbs) or 108 to 135 Newton-meters (Nm). Always consult the vehicle owner's manual or the wheel manufacturer's instructions for the specific torque recommendation. If overtorqued, lug nut of lug bolt can be fatigued, possibly leading to failure. If undertorqued, the lug nuts or lug bolts will not be securely installed and may become loose.
How to Properly Torque Wheels?
To ensure the proper torque is achieved, it is important to use a torque wrench when tightening lug nuts or lug bolts. A torque wrench allows for precise application of force and helps to prevent over-tightening or under-tightening. It is also important to tighten the lug nuts in a specific sequence, which can vary depending on the wheel bolt pattern.
Torque Pattern for Tightening and Loosening Lug Nuts
When tightening lug nuts and lug bolts on a wheel, follow a specific torque pattern to ensure even and secure tightening. Here are some commonly used torque patterns:
Wheel Torque Chart
Listed below are recommended wheel torque specs for most common lug bolt and lug nut sizes. Refer to your vehicle owner's manual for the correct torque settings.
| Lug Nut / Bolt Size | Torque Range (ft-lbs) | Number of Turns |
|---|---|---|
| M14x1.5 | 85 - 90 | 7.5 - 9.5 |
| M14x1.25 | 85 - 90 | 9 - 11 |
| M12x1.5 | 70 - 80 | 6.5 - 8 |
| M12x1.25 | 70 - 80 | 8 - 9.5 |
| 1/2"-20 | 75 - 85 | 8 - 10 |
| 7/16"-20 | 70 - 80 | 8.5 - 9 |
| 9/16"-18 | 135 - 145 | 8 - 10 |
