How to tighten them
- 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.
- Thread every nut or bolt on by hand until it seats against the wheel.
- Lower the vehicle so the tire takes its weight, and set a torque wrench to the value for your version in the table above.
- Tighten the nuts or bolts in a star pattern, going around two or three times, until the wrench clicks on every one.
- Check the torque again after a short drive if your manual says to.
What the Fiat manual adds
- Use only authorized dealer recommended lug nuts/bolts and clean or remove any dirt or oil before tightening.
- Tighten the lug nuts/bolts in a star pattern until each nut/bolt has been tightened twice.

Questions
What is the lug nut torque on a Fiat 500L?
89 lb-ft (120 N·m) for Aluminum wheels; 63 lb-ft (86 N·m) for Steel wheels, as printed in Fiat’s owner’s manuals (2014–2020).
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 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.
