How to tighten them

  1. Clean any dirt or rust off the studs, nuts or bolts and the wheel’s mounting face. Don’t oil them unless the manual says to.
  2. Thread every nut or bolt 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 the value for your version in the table above.
  4. Tighten the nuts or bolts in a star pattern, going around two or three times, until the wrench clicks on every one.
  5. Check the torque again after a short drive if your manual says to.

What the Fiat manual adds

  • Use only your authorized dealer recommended lug nuts/bolts and clean or remove any dirt or oil before tightening.

Questions

What is the lug nut torque on a Fiat 500 Abarth?

74 lb-ft (100 N·m) for Aluminum wheels (2017–2018); 66 lb-ft (90 N·m) for Steel wheels; 75 lb-ft (100 N·m) for Aluminum wheels (2014–2015), as printed in Fiat’s owner’s manuals (2014–2015, 2017–2018).

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 threads?

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