What size are the lug nuts on a 2018 Chevy Malibu?
For a 2018 Chevy Malibu in its factory configuration, the lug nuts use a 19 mm hex size with wheel studs that are M12 x 1.5 in diameter and pitch; the typical torque specification is around 100 ft-lbs (135 Nm).
The precise lug nut size and torque can vary if aftermarket wheels or different wheel assemblies are used, so always verify with the owner’s manual, the wheel manufacturer, or a dealership if you’re not certain.
Key lug nut specifications for the 2018 Malibu
The following specifications cover the standard OEM configuration typically cited by GM manuals and service guides. If you’re changing wheels or using aftermarket parts, confirm compatibility before proceeding.

Installation and maintenance tips
When installing or re-torquing lug nuts, use a proper torque wrench and follow a star-pattern sequence to ensure even seating. Do not rely on impact tools alone for final torque, and re-check torques after driving a short distance (e.g., 50–100 miles) if your vehicle’s maintenance schedule calls for it.
Additional considerations
If you install aftermarket wheels, confirm that the lug nuts’ seat type (conical, ball, or flat) matches the wheel’s lug seat design, and ensure your wrench size matches the nut hex. When in doubt, consult the wheel manufacturer or a qualified technician.
Summary
In short, the 2018 Chevy Malibu’s OEM lug nuts typically require a 19 mm wrench, fit M12 x 1.5 studs, and are torqued to about 100 ft-lbs. Verify these specs for any non-OEM wheels and always follow the vehicle’s torque recommendations and installation procedures.
