- Using a lug wrench or a torque wrench, loosen the lug nuts on the wheel you are working on, but do not remove them completely.
- Consult your vehicle’s owner’s manual or the table above to determine the appropriate torque specification for your lug nuts.
- Attach the appropriate socket to your torque wrench, matching the size of your lug nuts.
- Starting from the center and working in a star pattern, tighten each lug nut gradually, applying torque in small increments.
- Continue tightening until you reach the specified torque value.
- Once all lug nuts are torqued, double-check the tightness by attempting to loosen each nut slightly. If any lug nut moves, re-torque it to the specified value.
- Repeat the process for each wheel.
