Parts for your 2008 Nissan Primera-Wheel studs nuts

2008 Nissan Primera wheel studs and nuts — what they do and how to look after them

Based on Nissan’s factory Service Manual for the P12 Primera (Wheels & Tyres/WT section) and the Nissan Electronic Parts Catalogue, the 2008-registered Nissan Primera (P12 series) is built with wheel studs pressed into the hubs and secured with wheel nuts, not wheel bolts. Haynes’ service manual for the 2002–2007 Primera also details removal/refit using wheel nuts, confirming the stud-and-nut setup is the correct hardware for this model.

On the Primera, the job of the wheel studs and nuts is straightforward: the studs are fixed in the hub, the wheel slides over them, and the tapered-seat nuts clamp the wheel firmly against the hub face. It’s a simple, reliable design that speeds up wheel changes and keeps alignment true when a tyre’s swapped on the side of the road.

As part of regular servicing, it’s worth giving the wheel studs and nuts a quick once-over. Look for stretched threads, rusty or pitted studs, and rounded or cracked nuts. Any damage or heavy corrosion is a cue to replace the affected pieces straight away. Keep the mating faces clean and flat — no paint build-up, rust flakes, or trapped dirt between the wheel and hub.

When refitting wheels, the nuts should be tightened on clean, dry threads (no oil or grease unless the manufacturer specifically says otherwise) and torqued with a quality torque wrench to the specification in the owner’s handbook. For many P12 variants this typically sits in the ~98–108 N·m range, but always go by the exact figure listed for the vehicle. Use a star pattern to pull the wheel up evenly, and if a rattle gun was used initially, finish with a hand torque wrench for accuracy. After any wheel-off job, it’s good practice across Australia and New Zealand to recheck torque after 50–100 km of driving.

Replacing a damaged stud is a routine workshop task. The old stud is pressed or driven out of the hub flange and a new, correct-spec stud is pressed in squarely. Always match thread pitch and seat type (the Primera commonly uses a 60-degree tapered seat). Replace nuts in sets if the tapers are worn, and never mix nut styles across the same wheel.

• Inspect threads and tapers at each tyre rotation or brake service
• Clean hub and wheel mating faces before refit
• Tighten dry, in a star pattern, to the specified torque
• Re-torque after short running, especially after tyre or brake work

Popular questions

What size are the wheel studs and nuts on a 2008 Nissan Primera?
Most P12 Primeras use five M12 x 1.25 studs with 60-degree tapered-seat nuts. Variations can exist by market and wheel option, so it’s smart to confirm by VIN or checking the stamping on an existing nut before buying replacements.

What’s the correct torque for the wheel nuts?
Refer to the owner’s manual or the Service Manual torque chart for the exact figure. Many P12s sit around 98–108 N·m. Tighten on clean, dry threads and use a star pattern. If in doubt, a trusted workshop can set them with a calibrated torque wrench.

Should wheel studs or nuts be lubricated?
No. For this vehicle, torque values are intended for clean, dry threads. Lubrication can lead to over-tightening and stretched studs. A light wire-brush clean is fine, skip oils, anti-seize, and greases unless a specific Nissan bulletin instructs otherwise.
