Check Your Manual
- Your car owner's manual may have the manufacturer's specification for torquing the lug nuts. Always go with this specification, if you have it. If not, ask a dealer that sells your car's brand or contact an auto shop for the information.
- You should torque your car's lug nuts in as much of a star pattern as you can, that is, bottom right, top left, etc. This helps to secure the wheel onto the car, preventing wheel tilting.
- Lug nut torquing is expressed in foot-pounds. Use torque sticks with an air gun or a torque wrench to get the correct torque. If your studs or lug nuts are sized between 12 X 1.25mm to 1.5mm or are 7/16-inch, torque the nuts to 70 to 80 foot-lbs; 14 X 1.25mm to 1.5mm, to 85 or 90; 1/2=inch 75 to 85; and 9/16-inch 135 to 145.
