What size are the wheel nuts on a Toyota C-HR?
The wheel lug nuts on most Toyota C-HR models are M12 x 1.5 with a 60-degree conical seat, and the common socket size is 21 mm. However, aftermarket wheels can require different sizes, so it’s important to verify for your specific wheels.
In this article, we break down the lug nut specifications for the Toyota C-HR and explain how to confirm the correct size for your vehicle, including thread pitch, seat type, and the appropriate socket.
Lug nut specifications
Understanding the core specifications helps you choose the right tools and avoid damaging the lug nuts or wheels.
- Thread size: M12 x 1.5 (metric, common on modern Toyotas)
- Lug nut seat: 60-degree conical (seat type that mates with the wheel)
- Lug nut count on most C-HR models: 5-lug pattern
These specifications cover most factory wheels on C-HR models. If you have aftermarket rims, verify their requirements with the wheel manufacturer or your mechanic.
Socket size and verification
For the tools you’ll use to install or remove lug nuts, consider these common sizes and how to confirm them:
- Common hex size for Toyota lug nuts: 21 mm
- Note: Some aftermarket or steel wheels may use a 19 mm or other sized nut/socket
- Always confirm by checking the lug nut itself or the wheel specification label
Using the correct socket prevents rounding and ensures proper torque delivery for safe driving.
Summary
In most cases, the wheel nuts on the Toyota C-HR are M12 x 1.5 with a 60-degree conical seat, and a 21 mm socket is typically used. If you have aftermarket wheels, verify the exact size with the wheel manufacturer or a qualified mechanic to avoid damage.
