What size are the wheel nuts on a 2018 Chevy Cruze?
On the 2018 Chevy Cruze, the wheel nuts use standard GM lug hardware: thread size M12 × 1.5 with a 60-degree conical seat, and a 19 mm wrench fits the nuts. This applies to stock wheels; if you’re using aftermarket rims, verify the specifications before installation.
Understanding lug nut specifications
The following details explain what those numbers mean and how they apply to the Cruze's wheels.
- Thread size: M12 × 1.5
- Seat type: 60-degree conical (acorn) seat
- Nut head size: 19 mm (the wrench size needed)
- Lug pattern and count: 5 lugs per wheel with a 5 × 105 mm bolt pattern
These specifications cover the stock setup for the 2018 Cruze. If your wheels are aftermarket or modified, confirm the lug nut size with the wheel manufacturer or a dealer before installation.
Why this matters for maintenance and replacements
Using the correct lug nut size is essential for safety, proper seating, and avoiding damage to the wheel studs. If you're replacing wheels or performing a tire swap, ensure you obtain lug nuts that match the M12 × 1.5 thread, 60-degree conical seat, and the correct bolt pattern for your vehicle.
Verification and additional notes
When in doubt, check the owner's manual or consult a Chevrolet dealer. You can also physically inspect the lug nuts—GM/OnStar-style hub caps or dust covers may cover part of the nut, but the hex size and seat type should be consistent with the above specs.
Aftermarket wheels and safety considerations
If you plan to install aftermarket wheels, confirm compatibility with the factory studs, lug nut size (M12 × 1.5), seat type (60-degree conical), and bolt pattern (5 × 105 mm). Mismatched components can compromise safety and wheel retention.
Summary
The 2018 Chevy Cruze uses M12 × 1.5 lug nuts with a 60-degree conical seat, a 19 mm wrench size, and a 5 × 105 mm bolt pattern on stock wheels. Always verify if you switch to aftermarket rims, and consult the dealer or wheel manufacturer for exact compatibility.
