Trims and aftermarket considerations
OEM vs aftermarket wheels
Most 2014 Civics share the same M12 x 1.5 studs and conical-seat lug nuts, but aftermarket wheels can use different seat types or locking nuts. Always verify the exact lug-nut size and seat geometry for your specific wheels before purchasing replacements.
Locking lug nuts and compatibility
If your vehicle is equipped with locking lug nuts, keep the key in a secure place and ensure you have a compatible socket/adapter. Aftermarket wheels may also require different nut configurations, so consult the wheel supplier for the correct hardware and torque specifications.
Summary
For a 2014 Honda Civic, the standard lug nuts are M12 x 1.5 with a conical 60-degree seating, and the typical socket size is 19 mm. This applies to most OEM wheels on the sedan and coupe models. When switching to aftermarket wheels, verify lug-nut size, seat type, and torque with the wheel manufacturer or a trusted mechanic to ensure proper fit and safety.
