Overview of the standard lug-nut specs
The following specifications describe the common setup for OEM or OEM-equivalent wheels on the 2010 RX350. Always verify with your wheel or tire vendor if you’re using aftermarket components.

How to verify lug-nut size on your RX350
To confirm the correct lug-nut size for your specific vehicle, you can:
- Check the owner’s manual or the vehicle’s door jamb sticker for wheel and lug-nut specifications
- Inspect the lug nuts themselves for stamped size information
- Consult the wheel manufacturer or retailer if you purchased aftermarket wheels
- Ask a Toyota/Lexus service professional to confirm the exact specs for your wheel setup
Note: Always use the correct torque when reinstalling wheels. For stock RX350 wheels, ensure you follow the manufacturer’s torque specification to avoid over- or under-tightening.
