What size are the lug nuts on a Toyota Yaris?
The typical lug nut size for most Toyota Yaris models is a 12 mm wheel stud with a 1.5 mm thread pitch, using lug nuts that generally require a 19 mm socket. Some models or aftermarket wheels can differ, so always verify against your specific year, trim, and wheel type.
Common specifications for the Yaris
Here is the baseline information you’re most likely to encounter when servicing a Yaris wheel.
- Stud diameter: 12 mm
- Thread pitch: 1.5 (M12 x 1.5)
- Hex size for lug nuts (socket size): typically 19 mm
- Seat type: commonly conical (tapered) seat on stock wheels
- Torque for lug nuts: commonly around 103–112 Nm (76–83 ft-lbs); verify with the owner’s manual or service sheet for your exact model
Note: Some markets or aftermarket wheels may use different sizes or seat types (for example, 21 mm lug nuts or other seat designs). Always confirm the exact specification for your vehicle and wheels.
Model-year and regional variations
Generational notes
Across Yaris generations, the basic lug-nut size tends to remain around 12 mm studs with a 1.5 mm pitch in most markets. However, there can be exceptions for certain trims, editions, or regional specifications, especially between North American and European models.
Wheels and seat types to watch
Stock Toyota wheels typically use conical-seat lug nuts, but some aftermarket wheels require different seat types (such as ball or mushroom seats) and corresponding nuts. Always match the lug nut seat type to the wheel design to avoid improper seating or damage.
How to confirm your exact size
Use these steps to verify the correct lug nut size for your specific Yaris:
- Check the owner's manual or the door jamb/sticker for wheel lug nut specs and torque values.
- Consult a Toyota dealer or official parts catalog with your VIN or model/year to obtain exact specifications.
- Inspect the current lug nuts or measure the hex size with a socket that fits snugly; confirm the stud diameter and thread pitch if needed.
Confirming the exact spec ensures proper fitment and safe wheel installation, since incorrect lug nuts can cause wheel or stud damage.
Practical tips for maintenance and replacement
When replacing lug nuts or installing new wheels, consider these best practices:
- Always use the correct seat type and the correct thread size; using the wrong lug nut can damage wheels or studs.
- Torque the lug nuts to the manufacturer’s specification, using a star pattern to ensure even seating.
- Replace any damaged studs or lug nuts rather than reusing questionable hardware.
Adhering to these guidelines helps ensure safe wheel mounting and aligns with Toyota’s maintenance recommendations.
Summary
In the majority of Toyota Yaris models, you’ll encounter 12 mm wheel studs with a 1.5 mm thread pitch and lug nuts that typically require a 19 mm wrench. The approximate tightening torque is around 103–112 Nm (76–83 ft-lbs), but always verify for your exact year, market, and wheel configuration. When in doubt, consult the owner’s manual, a Toyota dealer, or the wheel manufacturer to confirm the precise lug nut size and torque.
