What size are the lug nuts on a gx470?
The GX470 uses M12 x 1.5 lug nuts with a 60-degree conical (acorn) seat, and OEM nuts are typically removed with a 19mm socket.
The Lexus GX 470, produced from 2003 to 2009, shares its wheel hardware with other Toyota-based SUVs of the era. Understanding the lug nut size, seat type, and related specs helps with tire changes, wheel upgrades, and maintaining proper torque to keep wheels secure.
Technical specifications
Below is a concise overview of the key lug-nut specs you’ll encounter on the GX470. The list covers the essential dimensions, seat type, and tool size to help you service wheels correctly.
- Thread size and pitch: M12 x 1.5
- Lug nut seat type: 60-degree conical (acorn) seat
- Nut hex size: typically 19mm for OEM lug nuts (some aftermarket options may require 21mm)
- Bolt pattern: 5 x 139.7 mm
- Recommended torque: around 80 ft-lb (approximately 108 Nm); always confirm with the vehicle’s manual or wheel manufacturer
These specifications align with Toyota-based SUVs of the era, including the GX470, and are intended to ensure proper seating on OEM and compatible aftermarket wheels. If you have aftermarket wheels with a different seat geometry, verify compatibility before installation.
What to know when replacing or shopping for lug nuts
When replacing lug nuts or upgrading wheels on the GX470, pay attention to seat design, thread pitch, and overall fit to protect wheels and studs. The following points help ensure you buy the right parts.
- Ensure the lug nuts match the wheel’s seat type (60-degree conical) to avoid improper seating or damage.
- Use the correct thread pitch (M12 x 1.5) and thread diameter to match the studs.
- Verify the hex size required by your wrench or socket (OEM is typically 19mm; some aftermarket nuts may use 21mm).
- Check the vehicle’s bolt pattern (5 x 139.7 mm) to confirm wheel compatibility.
- Follow torque specifications precisely (about 80 ft-lb / 108 Nm) and re-torque after a short drive if recommended by the wheel or vehicle manufacturer.
Choosing the right lug nuts protects wheel integrity and ensures safe driving. If you’re using aftermarket wheels, consult the wheel manufacturer’s recommendations and, if in doubt, use OEM-spec nuts or high-quality equivalents that match the seat and thread requirements.
Maintenance and practical tips
Practical guidance helps you maintain wheel security and avoid common issues during tire changes or rotations.
- Keep all lug nuts clean and free of corrosion; apply anti-seize only if recommended by the manufacturer, as some anodized or alloy wheels require none or specific compounds.
- Check lug-nut torque after the first 50–100 miles of driving or after any wheel change, then re-torque per the manufacturer’s schedule.
- Use a calibrated torque wrench and the correct socket size (typically 19mm for OEM GX470 lug nuts) to avoid under- or over-tightening.
- If you notice stripped threads, damaged seats, or uneven wheel seating, replace the stud or nut assembly and inspect the wheel for damage.
Summary
For the Lexus GX470, the standard lug-nut specification is M12 x 1.5 with a 60-degree conical seat, and OEM nuts typically require a 19mm wrench or socket. The wheel system is 5-lug with a 139.7 mm bolt circle. Always verify torque (about 80 ft-lb / 108 Nm) and seat compatibility, especially when using aftermarket wheels, to ensure safe and secure wheel installation.
