How to tighten them

  1. Clean any dirt or rust off the studs, the nuts and the wheel’s mounting face. Don’t oil them unless the manual says to.
  2. Thread every nut on by hand until it seats against the wheel.
  3. Lower the vehicle so the tire takes its weight, and set a torque wrench to 110 lb-ft (150 N·m).
  4. Tighten the nuts in a star pattern, going around two or three times, until the wrench clicks on every nut.
  5. Check the torque again after a short drive if your manual says to.

Questions

What is the lug nut torque on a Cadillac CT6?

110 lb-ft (150 N·m), as printed in Cadillac’s owner’s manuals (2016–2020).

Can I use an impact wrench?

Not to finish. An impact wrench can’t set a torque and easily overshoots it, which stretches studs. Run the nuts down by hand or lightly, then finish with a torque wrench in a star pattern.

Should I oil the studs?

Not unless the manual says so. Torque values assume clean, dry threads; oil lets the same torque stretch the stud further. Some manuals, Kia’s and Mazda’s among them, say to keep oil and grease off wheel nuts and bolts altogether.
