Factory vs. aftermarket wheels
Factory RX 350 wheels typically use the standard lug nut configuration described above, while aftermarket wheels can require different sizes, seat types, or locking nuts. Confirm compatibility with the specific wheel package you’re using.
How to verify the exact size for your vehicle
To confirm your RX 350’s exact lug nut size, you can use several reliable methods:
- Check the owner's manual or the tire/wheel specification page in your vehicle documents
- Inspect the door jamb placard, which often lists wheel and lug-related specs
- Look at the OEM wheel documentation or the wheel itself for nut size indicators
- Contact a Lexus dealer or service center with your VIN for an authoritative answer
In practice, the baseline configuration (M12 x 1.5, 60-degree conical seat, 21 mm hex) covers most RX 350 OEM wheels, but always confirm if you have aftermarket rims or locking nuts.

Can I use 7/8 socket for 22mm?
Yes, you can use a 7/8" socket for a 22mm bolt or nut because they are the same size, with a very small difference that is negligible in practice. 22mm is equal to approximately 0.8660.8660.866 inches, and 7/87 / 87/8 inch is equal to 0.8750.8750.875 inches.
- Size conversion: The two sizes are effectively interchangeable, as they are the closest imperial and metric equivalents.
- Fit: A 7/87 / 87/8" socket will fit on a 22mm bolt. It may feel a little loose, but it will still work.
- Impact tools: This combination is commonly used for impact tools, like those for lug nuts, where sockets are often stamped with both sizes.
- Warning: It's important to use a socket with the correct number of points (e.g., 6-point or 12-point) to avoid damaging the bolt or nut, especially on older or rounded-off fasteners.
