Parts for your 2022 Toyota C-hr-Wheel studs nuts

2022 Toyota C‑HR wheel studs and nuts: what they do and how to look after them

Technical confirmation: the 2022 Toyota C‑HR uses wheel studs and nuts (not wheel bolts). This is shown in the Toyota C‑HR Owner’s Manual (wheel changing section), which specifies tightening the wheel nuts to 103 N·m (76 ft·lbf), and in the Toyota Repair Manual for C‑HR (AX10/AX50 series) under Tyre and Wheel – Removal/Installation, which illustrates five pressed‑in hub studs with separate nuts. The model runs a 5‑stud hub (5×114.3 PCD) in AU/NZ.

On the C‑HR, the studs are the fixed threaded posts pressed into the hub, and the nuts clamp the wheel to the hub face. Together they create the clamping force that keeps the wheel seated, shares braking and cornering loads, and maintains a true, vibration‑free ride. Because Toyota uses a hub‑centric setup, the studs and nuts primarily provide clamping, the hub spigot locates the wheel.

As part of regular servicing or any tyre rotation, it’s smart to check the wheel nuts with a torque wrench, tightened to 103 N·m on clean, dry threads. Avoid lubricants or anti‑seize on the threads or nut seats, because torque specs are for dry assembly and lubrication can lead to over‑clamping. After any wheel off/on work, re‑torque after 50–100 kilometres. If a nut was rattled on with a rattle gun, always finish by hand‑torquing.

Studs or nuts should be replaced if threads are damaged, if a stud has stretched, if there’s visible corrosion pitting, or if a nut’s hex is deformed. Replacement of a stud on the C‑HR involves removing the wheel, brake caliper and rotor to press the old stud out and draw the new stud in squarely—best left to a workshop if you’re not set up. Mixing seat styles or using poor‑quality accessory nuts can cause loosening, so always match nuts to the wheel design and Toyota’s specs.

• Tighten in a star pattern to pull the wheel down evenly.
• Check torque after any tyre fitment, puncture repair or rotation.
• Never chase damaged threads with the nut—replace the affected parts.
• If one stud snaps, inspect the rest, repeated over‑torque can stress others.
• Use quality nuts with the correct thread (M12 × 1.5) and seat to suit the wheel.

Looked after this way, the C‑HR’s studs and nuts will deliver reliable clamping and quiet, confident driving on Aussie and Kiwi roads.

Popular questions about 2022 Toyota C‑HR wheel studs and nuts

What’s the correct wheel nut torque for a 2022 C‑HR, and should it be re‑checked?
Toyota specifies 103 N·m (76 ft·lbf) on clean, dry threads. After any wheel removal, it’s good practice to re‑check torque after 50–100 kilometres to account for paint crush or seating. Always tighten in a star pattern with a torque wrench.

How do you know a C‑HR wheel stud or nut needs replacing?
Look for chewed or flattened threads, rust pitting, a stud that’s necked or stretched, or a nut that no longer takes a socket cleanly. Any cross‑threading, binding, or a nut that won’t hold torque is a red flag—replace the affected stud/nut and inspect the rest.

Can lock nuts or aftermarket wheels be used safely on a C‑HR?
Yes, provided the nuts match Toyota’s thread (M12 × 1.5) and the seat profile suits the wheel. Ensure the wheel is hub‑centric to the C‑HR and always torque to 103 N·m. Poorly matched nuts or seats can loosen and damage the wheel.
