Most Honda passenger cars use M12 x 1.5 lug nuts with a 19 mm wrench size. However, exact sizing can vary by model, year, and aftermarket wheels, so it’s best to verify for your specific vehicle.
The question of lug-nut size depends on the particular Honda you own. While there is a common baseline, the exact specification can differ, especially if your car has aftermarket wheels or a rare trim. This article outlines the typical sizes you’re likely to encounter and how to confirm yours.
Common lug-nut sizes you’ll encounter on Honda models
The following bullets describe the typical specs you’ll see on modern Honda passenger cars and light trucks. Use this as a baseline but confirm for your exact model and wheel configuration.
- Thread size: M12 x 1.5 (most Honda passenger cars)
- Nut size across flats (hex): 19 mm
- Variations: Some older Hondas or certain wheels may use a different hex size, or aftermarket wheels may require different nuts
- Locking lug nuts: Some vehicles include locking lug nuts with a unique key; ensure you have the key if your wheels came with one
In most cases, you’ll be dealing with M12 x 1.5 thread and a 19 mm hex. If you’re unsure, check the owner’s manual or contact a Honda dealer with your VIN to confirm the exact specification for your car.
How to verify your specific Honda model
Use these steps to confirm the exact lug-nut size for your car, especially if you have aftermarket wheels or a variant year.
- Look up your vehicle’s manual or the manufacturer’s online spec sheet for lug-nut size
- Inspect the lug nuts on your wheels for any size markings or stamps
- Remove a lug nut and measure across flats with a caliper or a socket gauge to determine the hex size (for example, 19 mm)
- Confirm the thread pitch on the studs (M12 x 1.5 is common for most Hondas)
- If in doubt, contact your local Honda dealer or parts department with your VIN to verify the exact specification
By confirming the exact spec for your vehicle and wheel, you avoid cross-threading or damage and ensure safe tire changes.
Notes for Honda owners
Model-year and wheel variations
Because lug-nut sizing can vary by year, trim, and aftermarket wheels, always check the exact specification for your car. Relying on a generic baseline without verification can lead to improper fitment when replacing lug nuts or wheels.
Summary
For the majority of Honda models, lug nuts are M12 x 1.5 with a 19 mm hex. Always verify the size for your exact year, model, and wheel setup by consulting the owner’s manual, checking wheel hardware, or contacting a Honda dealer with your VIN. This helps ensure safe installation and proper torque when changing tires.
