Why Lug Nut Size Matters
Knowing the correct lug nut size is crucial for several reasons:
- Wheel Removal and Installation: Using the proper size lug wrench or socket ensures the lug nuts can be loosened and tightened securely without stripping the nut or damaging the wheel.
- Tire Rotations and Replacements: When rotating tires or replacing wheels, having the right lug nut size on hand makes the process faster and easier.
- Safety: Properly tightened lug nuts help ensure the wheels remain firmly attached to the vehicle, preventing dangerous wheel separation incidents.
Consulting your owner's manual or contacting your local Honda dealer are the best ways to confirm the exact lug nut size for your 2018 Civic Si.
