The OEM lug nuts for a 2008 Chevy Malibu are M12 x 1.5 with a 60-degree conical seat, typically a 19 mm hex, used on a 5x115 bolt pattern, with a torque spec around 100 ft-lb. Always verify with your wheel and owner manual, as variations can occur with different trims or aftermarket wheels.
Stock lug nut specifications
The following specifications reflect the factory configuration for most 2008 Malibu models equipped with the standard wheels. They cover the essential measurements you’ll need when selecting replacements or checking fitment.
- M12 x 1.5 thread size for the lug studs (12 mm diameter, 1.5 mm pitch).
- 60-degree conical (acorn) seat to match OEM wheels.
- 19 mm (3/4 inch) hex size for the factory lug nuts.
- Bolt pattern: 5 bolts on a 115 mm circle (5x115).
- Typical tightening torque: about 100 ft-lb (135 Nm) for stock lug nuts; always verify with GM service data or the wheel manufacturer.
Note: If your Malibu uses aftermarket wheels or different trims, lug nut specifications can vary. Always confirm with the wheel manufacturer or a GM service document before installation.
Verifying lug nut specs for your wheels
To ensure you’re using the correct hardware, consult the owner's manual, the service manual, or the sticker on the wheel well or inner door jamb for your vehicle. If you are replacing lost lug nuts, use OEM replacements or wheel-specific nuts recommended by GM or the wheel manufacturer.
Additional considerations
Some aftermarket wheels may require different seat types or hex sizes. If you have wheels from a replacement program, a different trim level, or a non-OEM wheel, double-check the lug nut size, thread pitch, and seat type before purchase. If in doubt, take a sample nut to a parts retailer or contact the wheel manufacturer for exact specifications.
Summary
For a 2008 Chevy Malibu, expect lug nuts that are M12 x 1.5 with a 60-degree conical seat, a 19 mm hex size, and a 5x115 bolt pattern, tightened to roughly 100 ft-lb. Variations can occur with aftermarket wheels or non-standard trims, so verify every time you replace wheels or lug nuts.
